I am working on setting up a Salesforce Helper Library to send SMS's from Salesforce using Apex. I am able to send SMS's 1 by 1 using the information from their documentation.
I came across an article about their new API feature: Passthrough API which lets us send bulk SMS's using their API. https://www.twilio.com/blog/2017/08/bulk-sms-with-one-api-request.html
I would like to know if this feature is supported for Salesforce Helper Library ?
