Security Updates to Messaging API & Portal

18, Mar 2024

In order to improve the security of Telnyx’s Messaging platform for end users, we have implemented two changes to Messaging Profiles:

  1. Editing / Creating a Messaging or Verify Profile via the Portal and API will require users to configure whitelisted destination countries for outbound termination. Note that existing profiles will not be affected - only those that are newly edited or created.
  2. When attempting to send to non-US destinations, Telnyx now requires a default Alphanumeric sender ID to be named on the Messaging Profile.

Further information:
