Does Drupal 7 "CiviCRM Entity" online event registration generate confirmation email?
Assuming you used the Price Set Entity field to get the registration form.
The confirmation email was never fleshed out totally.
There are also 2 Rules Events you can react to:
&quot;Event Registration&quot; and &quot;Successful CC Transaction&quot;
Which then you could use Drupal's stock &quot;Send email&quot; action ...
We do have a Rules action, &quot;Send Contribution API sendconfirmation&quot; .. which does what it says .. for the contribution created, it runs the Contribution API entity, &quot;sendconfirmation&quot; action ..
Which is ok unless there is no contribution.
We'd also done some things where we implement hook_form_alter() and add a submit handler ..and programmatically send an email on form submission.
