I am experiencing an issue when trying to set up the SMS function with Twilio in my dashboard (as shown in the attached screenshot).
Problem Details:
What I did: I filled in both my correct Twilio Account SID and Twilio Auth Token, and then clicked the “Save” button.
What happened: The system doesn’t seem to save the credentials. Every time I click back into the “Setup SMS Function” modal, the fields are completely blank again, and the configuration fails to apply to my inbound/outbound calls.
Could you please help check if this is a backend bug or if there is something wrong with the credential verification process?
Just confirmed with the team , What you’re seeing on re-open is expected behavior, not a save failure.
The Setup SMS Function modal is stateless by design. It does not prefill previously saved credentials (the Auth Token is intentionally never sent back to the browser). The grey “Enter Account SID / Enter Twilio Auth Token” text is just HTML placeholder, and the Save button is greyed out until both fields have text. Blank on re-open is not a bug.
To verify a save worked: re-enter both credentials and click Save. The modal closing without an error means it succeeded. To confirm SMS is actually working, send a test message through the configured number rather than checking the modal.
If SMS still isn’t applying to your calls after re-saving, share your org ID (https://docs.retellai.com/accounts/workspace) and the phone number (E.164 format) and we can pull the server-side record to confirm credentials persisted and check the full SMS setup (agent assignment, A2P 10DLC status for US numbers, etc.).
