Twilio Invalid 'StatusCallbackEvent' Error - 21626

Question

One or more of the StatusCallbackEvents provided were invalid.

invalidStatusCallbackEvents "canceled no-answer busy failed"

I removed those 4 events from above since they do not seem to ever be valid according to:

• https://support.twilio.com/hc/en-us/articles/223132267-Tracking-the-call-status-of-an-outbound-call
• the invalid callback events are actually finalized call statuses: https://support.twilio.com/hc/en-us/articles/223132547-What-are-the-Possible-Call-Statuses-and-What-do-They-Mean-

Is this the correct way to fix the issue? Or are those 4 StatusCallbackEvents valid under some context?

Twilio developer evangelist here.

You're correct, none of those are events, they are statuses. In fact, they are all statuses that could be sent as part of the "completed" event.

The call events you can register for callbacks for are: initiated, ringing, answered and completed.
