I need to send faxes programmatically (ie using the API) with a different caller Id depending on which of my employer's subsidiary the fax is sent for.
I looked at all the parameters offered in the API call and none of them apparently let's me do that.
How am I supposed to send a fax with a different caller Id? Do I need to change credentials depending on which caller Id number I want to use?
Do I need to change the client id and secret to or only the username and password?
Changing them on a per fax basis does not feel quite scalable so there has to be another way...
Thank you and have a nice day,
