Summary: Adds a delivery_status response field to SMS session and message endpoints, and introduces a sort request field to SMS session APIs to control result ordering.

Changed

  • New delivery_status response field in the following SMS APIs:
    • GET /v2/phone/sms/sessions/{sessionId}
    • GET /v2/accounts/{accountId}/phone/sms/sessions/{sessionId}
    • GET /v2/accounts/{accountId}/phone/sms/sessions/{sessionId}/messages/{messageId}
    • GET /v2/phone/sms/sessions/{sessionId}/messages/{messageId}
  • New sort request field in the following SMS APIs:
    • GET /v2/phone/sms/sessions/{sessionId}
    • GET /v2/accounts/{accountId}/phone/sms/sessions/{sessionId}

I am not seeing consistent results when setting sort which can lead to duplicate messages when using page limit and next page token.
