I am using Docusign Login information api in a mapping with Informatica Cloud .
The mapping executes successfully with a fault response.The error message in the fault response is as follows.I have tested the same api in postman.I am using Integrator Key provided by Docusign for authentication along with my username and password.The API works perfect in postman.But with Informtica Cloud it gives me following error.
I have created swagger file with username,Password and integrator key as headers for creating the web service in Informatica Cloud.I am using Authentication type as 'Basic' in the connector and in swagger file.Where I am I going wrong with authentication?The Integrator Key or the username and password are valid.

```
Unauthorized {

  "errorCode": "AUTHORIZATION_INVALID_TOKEN",

  "message": "The access token provided is expired, revoked or malformed."

}
