  Using this function you can:
  * Create an envelope and send it.
  * Create an envelope from an existing template and send it.
  
  In either case, you can choose to save the envelope as a draft envelope instead of sending it by setting the request's `status` property to `created` instead of `sent`.
  
  ## Sending Envelopes
  
  Documents can be included with the Envelopes::create call itself or a template can include documents. Documents can be added by using a multi-part/form request or by using the `documentBase64` field of the [`document` object](#/definitions/document)
  
  ### Recipient Types
  An [`envelopeDefinition` object](#/definitions/envelopeDefinition) is used as the method's body. Envelope recipients can be defined in the envelope or in templates. The `envelopeDefinition` object's `recipients` field is an [`EnvelopeRecipients` resource object](#/definitions/EnvelopeRecipients). It includes arrays of the seven types of recipients defined by DocuSign:
  
  Recipient type | Object definition
  -------------- | -----------------
  agent (can add name and email information for later recipients/signers) | [`agent`](#/definitions/agent)
  carbon copy (receives a copy of the documents) | [`carbonCopy`](#/definitions/carbonCopy)
  certified delivery  (receives a copy of the documents and must acknowledge receipt) | [`certifiedDelivery`](#/definitions/certifiedDelivery)
  editor (can change recipients and document fields for later recipients/signers) | [`editor`](#/definitions/editor)
  in-person signer ("hosts" someone who signs in-person) | [`inPersonSigner`](#/definitions/inPersonSigner)
  intermediary (can add name and email information for some later recipients/signers.) | [`intermediary`](#/definitions/intermediary)
  signer (signs and/or updates document fields) | [`signer`](#/definitions/signer)
  
  Additional information about the different types of recipients is available from the [`EnvelopeRecipients` resource page](../../EnvelopeRecipients) and from the [Developer Center](https://www.docusign.com/developer-center/explore/features/recipients)
  
  ### Tabs
  Tabs (also referred to as `tags` and as `fields` in the web sending user interface), can be defined in the `envelopeDefinition`, in templates, by transforming PDF Form Fields, or by using Composite Templates (see below).
  
  Defining tabs: the `inPersonSigner`, and `signer` recipient objects include a `tabs` field. It is an [`EnvelopeTabs` resource object](#/definitions/EnvelopeTabs). It includes arrays of the 24 different tab types available. See the [`EnvelopeTabs` resource](../../EnvelopeTabs) for more information.
  
  ## Using Templates
  Envelopes use specific people or groups as recipients. Templates can specify a role, eg `account_manager.` When a template is used in an envelope, the roles must be replaced with specific people or groups.
  
  When you create an envelope using a `templateId`, the different recipient type objects within the [`EnvelopeRecipients` object](#/definitions/EnvelopeRecipients) are used to assign recipients to the template's roles via the `roleName` property. The recipient objects can also override settings that were specified in the template, and set values for tab fields that were defined in the template.
  
  ### Message Lock
  When a template is added or applied to an envelope and the template has a locked email subject and message, that subject and message are used for the envelope and cannot be changed even if another locked template is subsequently added or applied to the envelope. The field `messageLock` is used to lock the email subject and message.
  
  If an email subject or message is entered before adding or applying a template with `messageLock` **true**, the email subject and message is overwritten with the locked email subject and message from the template.
  
  ## Envelope Status
  The status of sent envelopes can be determined through the DocuSign webhook system or by polling. Webhooks are highly recommended: they provide your application with the quickest updates when an envelope's status changes. DocuSign limits polling to once every 15 minutes or less frequently.
  
  When a webhook is used, DocuSign calls your application, via the URL you provide, with a notification XML message. 
  
  See the [Webhook recipe](https://www.docusign.com/developer-center/recipes/webhook-status) for examples and live demos of using webhooks.
  
  ## Webhook Options
  The two webhook options, *eventNotification* and *Connect* use the same notification mechanism and message formats. eventNotification is used to create a webhook for a specific envelope sent via the API. Connect webhooks can be used for any envelope sent from an account, from any user, from any client. 
  
  ### eventNotification Webhooks
  The Envelopes::create method includes an optional [eventNotification object](#definition-eventNotification) that adds a webhook to the envelope. eventNotification webhooks are available for all DocuSign accounts with API access.
  
  ### Connect Webhooks
  Connect can be used to create a webhook for all envelopes sent by all users in an account, either through the API or via other DocuSign clients (web, mobile, etc). Connect configurations are independent of specific envelopes. A Connect configuration includes a filter that may be used to limit the webhook to specific users, envelope statuses, etc. 
  
  Connect configurations may be created and managed using the [ConnectConfigurations resource](../../Connect/ConnectConfigurations). Configurations can also be created and managed from the Administration tool accessed by selecting "Go to Admin" from the menu next to your picture on the DocuSign web app. See the Integrations/Connect section of the Admin tool. For repeatability, and to minimize support questions, creating Connect configurations via the API is recommended, especially for ISVs.
  
  Connect is available for some DocuSign account types. Please contact DocuSign Sales for more information.
  
  ## Composite Templates
  
  The Composite Templates feature, like [compositing in film production](https://en.wikipedia.org/wiki/Compositing), enables you to *overlay* document, recipient, and tab definitions from multiple sources, including PDF Form Field definitions, templates defined on the server, and more.
  
  Each Composite Template consists of optional elements: server templates, inline templates, PDF Metadata templates, and documents.
  
  * The Composite Template ID is an optional element used to identify the composite template. It is used as a reference when adding document object information via a multi-part HTTP message. If used, the document content-disposition must include the `compositeTemplateId` to which the document should be added. If `compositeTemplateId` is not specified in the content-disposition, the document is applied based on the `documentId` only. If no document object is specified, the composite template inherits the first document.
  
  * Server Templates are server-side templates stored on the DocuSign platform. If supplied, they are overlaid into the envelope in the order of their Sequence value.
  
  * Inline Templates provide a container to add documents, recipients, tabs, and custom fields. If inline templates are supplied, they are overlaid into the envelope in the order of their Sequence value.
  
  * Document objects are optional structures that provide a container to pass in a document or form. If this object is not included, the composite template inherits the *first* document it finds from a server template or inline template, starting with the lowest sequence value.
  
  PDF Form objects are only transformed from the document object. DocuSign does not derive PDF form properties from server templates or inline templates. To instruct DocuSign to transform fields from the PDF form, set `transformPdfFields` to "true" for the document. See the Transform PDF Fields section for more information about process.
  
  * PDF Metadata Templates provide a container to embed design-time template information into a PDF document. DocuSign uses this information when processing the Envelope. This convention allows the document to carry the signing instructions with it, so that less information needs to be provided at run-time through an inline template or synchronized with an external structure like a server template. PDF Metadata templates are stored in the Metadata layer of a PDF in accordance with Acrobat's XMP specification. DocuSign will only find PDF Metadata templates inside documents passed in the Document object (see below). If supplied, the PDF metadata template will be overlaid into the envelope in the order of its Sequence value.
  
  ### Compositing the definitions
  Each Composite Template adds a new document and templates overlay into the envelope. For each Composite Template these rules are applied:
  
  * Templates are overlaid in the order of their Sequence value.
  * If Document is not passed into the Composite Template's `document` field, the *first* template's document (based on the template's Sequence value) is used.
  * Last in wins in all cases except for the document (i.e. envelope information, recipient information, secure field information). There is no special casing.
  
  For example, if you want higher security on a tab, then that needs to be specified in a later template (by sequence number) then where the tab is included. If you want higher security on a role recipient, then it needs to be in a later template then where that role recipient is specified.
  
  * Recipient matching is based on Recipient Role and Routing Order. If there are matches, the recipient information is merged together. A final pass is done on all Composite Templates, after all template overlays have been applied, to collapse recipients with the same email, username and routing order. This prevents having the same recipients at the same routing order.
  
  * If you specify in a template that a recipient is locked, once that recipient is overlaid the recipient attributes can no longer be changed. The only items that can be changed for the recipient in this case are the email, username, access code and IDCheckInformationInput.
  
  * Tab matching is based on Tab Labels, Tab Types and Documents. If a Tab Label matches but the Document is not supplied, the Tab is overlaid for all the Documents.
  
  For example, if you have a simple inline template with only one tab in it with a label and a value, the Signature, Initial, Company, Envelope ID, User Name tabs will only be matched and collapsed if they fall in the exact same X and Y locations.
  
  * roleName and tabLabel matching is case sensitive.
  
  * The defaultRecipient field enables you to specify which recipient the generated tabs from a PDF form are mapped to. You can also set PDF form generated tabs to a recipient other than the DefaultRecipient by specifying the mapping of the tab label that is created to one of the template recipients.
  
  * You can use tabLabel wild carding to map a series of tabs from the PDF form. To use this you must end a tab label with "\*" and then the system matches tabs that start with the label.
  
  * If no DefaultRecipient is specified, tabs must be explicitly mapped to recipients in order to be generated from the form. Unmapped form objects will not be generated into their DocuSign equivalents. (In the case of Signature/Initials, the tabs will be disregarded entirely; in the case of pdf text fields, the field data will be flattened on the Envelope document, but there will not be a corresponding DocuSign data tab.)
  
  ### Including the Document Content for Composite Templates
  Document content can be supplied inline, using the `documentBase64` or can be included in a multi-part HTTP message. 
  If a multi-part message is used and there are multiple Composite Templates, the document content-disposition can include the `compositeTemplateId` to which the document should be added. Using the `compositeTemplateId` sets which documents are associated with particular composite templates. An example of this usage is:
  
  ```
     --5cd3320a-5aac-4453-b3a4-cbb52a4cba5d
     Content-Type: application/pdf
     Content-Disposition: file; filename="eula.pdf"; documentId=1; compositeTemplateId="1"
     Content-Transfer-Encoding: base64
  ```
  
  ### PDF Form Field Transformation
  Only the following PDF Form FieldTypes will be transformed to DocuSign tabs: CheckBox, DateTime, ListBox, Numeric, Password, Radio, Signature, and Text
  
  Field Properties that will be transformed: Read Only, Required, Max Length, Positions, and Initial Data.
  
  When transforming a *PDF Form Digital Signature Field,* the following rules are used:
  
  If the PDF Field Name Contains | Then the DocuSign Tab Will be
  ------- | --------
  DocuSignSignHere or eSignSignHere | Signature
  DocuSignSignHereOptional or eSignSignHereOptional | Optional Signature
  DocuSignInitialHere or eSignInitialHere | Initials
  DocuSignInitialHereOptional or eSignInitialHereOptional | Optional Initials
  
  Any other PDF Form Digital Signature Field will be transformed to a DocuSign Signature tab
  
  When transforming *PDF Form Text Fields,* the following rules are used:
  
  If the PDF Field Name Contains | Then the DocuSign Tab Will be
  ------- | --------
  DocuSignSignHere or eSignSignHere | Signature
  DocuSignSignHereOptional or eSignSignHereOptional | Optional Signature
  DocuSignInitialHere or eSignInitialHere | Initials
  DocuSignInitialHereOptional or eSignInitialHereOptional | Optional Initials
  DocuSignEnvelopeID or eSignEnvelopeID | EnvelopeID
  DocuSignCompany or eSignCompany | Company
  DocuSignDateSigned or eSignDateSigned | Date Signed
  DocuSignTitle or eSignTitle | Title
  DocuSignFullName or eSignFullName |  Full Name
  DocuSignSignerAttachmentOptional or eSignSignerAttachmentOptional | Optional Signer Attachment
  
  Any other PDF Form Text Field will be transformed to a DocuSign data (text) tab.
  
  PDF Form Field Names that include "DocuSignIgnoreTransform" or "eSignIgnoreTransform" will not be transformed.
  
  PDF Form Date fields will be transformed to Date Signed fields if their name includes DocuSignDateSigned or eSignDateSigned.
  
  ## Template Email Subject Merge Fields
  This feature enables you to insert recipient name and email address merge fields into the email subject line when creating or sending from a template.
  
  The merge fields, based on the recipient's `roleName`, are added to the `emailSubject` when the template is created or when the template is used to create an envelope. After a template sender adds the name and email information for the recipient and sends the envelope, the recipient information is automatically merged into the appropriate fields in the email subject line.
  
  Both the sender and the recipients will see the information in the email subject line for any emails associated with the template. This provides an easy way for senders to organize their envelope emails without having to open an envelope to check the recipient.
  
  If merging the recipient information into the subject line causes the subject line to exceed 100 characters, then any characters over the 100 character limit are not included in the subject line. For cases where the recipient name or email is expected to be long, you should consider placing the merge field at the start of the email subject.
  
  * To add a recipient's name in the subject line add the following text in the `emailSubject` when creating the template or when sending an envelope from a template:
  
     [[<roleName>_UserName]]
  
     Example:
  
     `"emailSubject":"[[Signer 1_UserName]], Please sign this NDA",`
  
  * To add a recipient's email address in the subject line add the following text in the emailSubject when creating the template or when sending an envelope from a template:
  
     [[<roleName>_Email]]
  
     Example:
  
     `"emailSubject":"[[Signer 1_Email]], Please sign this NDA",`
  
  In both cases the <roleName> is the recipient's `roleName` in the template.
  
  For cases where another recipient (such as an Agent, Editor, or Intermediary recipient) is entering the name and email information for the recipient included in the email subject, then [[<roleName>_UserName]] or [[<roleName>_Email]] is shown in the email subject.
  
  ## Branding an envelope
  The following rules are used to determine the `brandId` used in an envelope:
  
  * If a `brandId` is specified in the envelope/template and that brandId is available to the account, that brand is used in the envelope.
  * If more than one template is used in an envelope and more than one `brandId` is specified, the first `brandId` specified is used throughout the envelope.
  * In cases where no brand is specified and the sender belongs to a Group; if there is only one brand associated with the Group, then that brand is used in the envelope. Otherwise, the account's default signing brand is used.
  * For envelopes that do not meet any of the previous criteria, the account's default signing brand is used for the envelope.
  
  ## BCC Email address feature 
  The BCC Email address feature is designed to provide a copy of all email communications for external archiving purposes. DocuSign recommends that envelopes sent using the BCC for Email Archive feature, including the BCC Email Override option, include additional signer authentication options. To send a copy of the envelope to a recipient who does not need to sign, don't use the BCC Email field. Use a Carbon Copy or Certified Delivery Recipient type.
  
  ## Merge Recipient Roles for Draft Envelopes
  When an envelope with multiple templates is sent, the recipients from the templates are merged according to the template roles, and empty recipients are removed. When creating an envelope with multiple templates, but not sending it (keeping it in a created state), duplicate recipients are not merged, which could cause leave duplicate recipients in the envelope.
  
  To prevent this, the query parameter `merge_roles_on_draft` should be added when posting a draft envelope (status=created) with multiple templates. Doing this will merge template roles and remove empty recipients.
  
  ###### Note: DocuSign recommends that the `merge_roles_on_draft` query parameter be used anytime you are creating an envelope with multiple templates and keeping it in draft (created) status.

      /**
       * Gets status changes for one or more envelopes.
       * Retrieves envelope status changes for all envelopes. You can modify the information returned by adding query strings to limit the request to check between certain dates and times, or for certain envelopes, or for certain status codes. It is recommended that you use one or more of the query strings in order to limit the size of the response.
  
  ### Important: Unless you are requesting the status for specific envelopes (using the `envelopeIds` or `transactionIds` properties), you must add a set the `from_date` property in the request.
  
  Getting envelope status using `transactionIds` is useful for offline signing situations where it can be used determine if an envelope was created or not, for the cases where a network connection was lost, before the envelope status could be returned.
  
  ### Request Envelope Status Notes ###
  
  The REST API GET /envelopes call uses certain filters to find results. In some cases requests are check for "any status change" instead of the just the single status requested. In these cases, more envelopes might be returned by the request than otherwise would be. For example, for a request with the begin date is set to Jan 1st, an end date set to Jan 7th and the status qualifier (`from_to_status`) set to `Delivered` &mdash; the response set might contain envelopes that were created during that time period, but not delivered during the time period.
  
  To avoid unnecessary database queries, the DocuSign system checks requests to ensure that the added filters will not result in a zero-size response before acting on the request. The following table shows the valid envelope statuses (in the Valid Current Statuses column) for the status qualifiers in the request. If the status and status qualifiers in the API request do not contain any of the values shown in the valid current statuses column, then an empty list is returned.
  
  For example, a request with a status qualifier (from_to_status) of `Delivered` and a status of "`Created`,`Sent`", DocuSign will always return an empty list. This is because the request essentially translates to: find the envelopes that were delivered between the begin and end dates that have a current status of `Created` or `Sent`, and since an envelope that has been delivered can never have a status of `Created` or `Sent`, a zero-size response would be generated. In this case, DocuSign does not run the request, but just returns the empty list.
  
  Client applications should check that the statuses they are requesting make sense for a given status qualifier.
       * @param {String} accountId The external account number (int) or account ID Guid.
       * @param {Object} optsOrCallback Optional parameters, if you are passing no optional parameters, you can either pass a null or omit this parameter entirely.
       * @param {String} optsOrCallback.acStatus Specifies the Authoritative Copy Status for the envelopes. The possible values are: Unknown, Original, Transferred, AuthoritativeCopy, AuthoritativeCopyExportPending, AuthoritativeCopyExported, DepositPending, Deposited, DepositedEO, or DepositFailed.

       * @param {String} optsOrCallback.continuationToken 
       * @param {String} optsOrCallback.count 
       * @param {String} optsOrCallback.customField This specifies the envelope custom field name and value searched for in the envelope information. The value portion of the query can use partial strings by adding '%' (percent sign) around the custom field query value.   Example 1: If you have an envelope custom field called \"Region\" and you want to search for all envelopes where the value is \"West\" you would use the query: `?custom_field=Region=West`.   Example 2: To search for envelopes where the `ApplicationID` custom field has the value or partial value of \"DocuSign\" in field, the query would be: `?custom_field=ApplicationId=%DocuSign%` This would find envelopes where the custom field value is \"DocuSign for Salesforce\" or \"DocuSign envelope.\"

       * @param {String} optsOrCallback.fromToStatus This is the status type checked for in the `from_date`/`to_date` period. If `changed` is specified, then envelopes that changed status during the period are found. If for example, `created` is specified, then envelopes created during the period are found. Default is `changed`.   Possible values are: Voided, Changed, Created, Deleted, Sent, Delivered, Signed, Completed, Declined, TimedOut and Processing.

       * Send Draft Envelope/Void Envelope/Move/Purge Envelope/Modify draft
       * The Put Envelopes endpoint provides the following functionality:
  
  * Sends the specified single draft envelope.
  Add {"status":"sent"} to the request body to send the envelope.
  
  * Voids the specified in-process envelope.
  Add {"status":"voided", "voidedReason":"The reason for voiding the envelope"} to the request body to void the envelope.
  
  * Replaces the current email subject and message for a draft envelope.
  Add {"emailSubject":"subject",  "emailBlurb":"message"}  to the request body to modify the subject and message.
  
  * Place the envelope documents and envelope metadata in a purge queue so that this information is removed from the DocuSign system.
  Add {"purgeState":"purge type"} to the request body.
  
  *Additional information on purging documents*
  
  The purge request can only be used for completed envelopes that are not marked as the authoritative copy. The requesting user must have permission to purge documents and must be the sender (the requesting user can act as the sender using Send On Behalf Of).
  
  ###### Note: If you have set the Document Retention policy on your account, envelope documents are automatically placed in the purge queue and the warning emails are sent at the end of the retention period. 
  ###### Note: You can set the Document Retention policy in the Classic DocuSign Experience by specifying the number of days to retain documents. 
  ###### Note: Setting a Document Retention policy is the same as setting a schedule for purging documents.
  
  When the purge request is initiated the envelope documents, or documents and envelope metadata, are placed in a purge queue for deletion in 14 days. A warning email notification is sent to the sender and recipients associated with the envelope, notifying them that the envelope documents will be deleted in 14 days and providing a link to the documents. A second email is sent 7 days later with the same message. At the end of the 14-day period, the envelope documents are deleted from the system.
  
  If `purgeState="documents_queued"` is used in the request, then only the documents are deleted and any corresponding attachments and tabs remain in the DocuSign system. If `purgeState= "documents_and_metadata_queued"` is used in the request, then the documents, attachments, and tabs are deleted.
