Content Templates no longer need to be sent with Messaging Services
Sending Content Templates with a messaging service sid in the from or a MessagingServiceSid field is now optional!
Previously using a messaging service and specifying its sid was a requirement to use Content Templates. Now customers can send a content template by using the standard to and from fields containing a phone number with the sender prefix if relevant.
Previous methods of sending a content template using messaging service sid will still be supported.
Now Content Templates can be sent with the following parameters
