A2P 10DLC Campaign Vetting Delays: We are experiencing delays while vetting 10DLC campaigns. Our third party is reviewing campaigns manually, and due to the high volume of requests, a queue has built up. Campaign reviews are expected to take longer. Twilio is working with the provider to help expedite this process. New details will be shared in our incident report as soon they become available.

Switching from SMS/Messages resource URI to Messages resource URI

SMS/Messages is a deprecated resource that we no longer maintain or updated and may be removed in future versions of the Twilio API.

Newly released features are only available in the/Messages resource. We highly recommend you to move onto the new /Messages resource for your application. The change normally involves a quick helper library update and a few lines of code changes. Check out the sample code on how to use the new endpoint to send messages.

For your reference, below is a sample list of features that are available only in the /Messages resource:

  • Send concatenated messages with up to 1600 characters
  • Receive message delivery status information of your messages
  • Send MMS messages in the US and Canada
  • Take advantage of the “MaxPrice” parameter to control message costs
  • Utilize Messaging Services
  • Access to detailed delivery steps in the SMS log within Console
  • Send messages to non-SMS channels like WhatsApp.
