Messaging API response & Logs with default messaging service

Twilio programmable messaging’s POST request will return the messaging_service_sid parameter with a default value for messages which did not specify one in the POST request. This default value will be unique for each account_sid. This default value will also show up for each message in the messaging_service_sid field of messages logs.

A new messaging service will be auto-generated for your account. This messaging service will be named “[Auto-generated] Default Messaging Service”.
