Debugging your Function
Twilio is launching a new Console. Some screenshots on this page may show the Legacy Console and therefore may no longer be accurate. We are working to update all screenshots to reflect the new Console experience. Learn more about the new Console.
Console Debugging
If you are actively working on your Function, you can show live logs for debugging by loading the Function page:
All invocation and logs will stream to your browser in near-realtime.
The logs are not persisted, and only show up while you are on the Function page.
Logs are limited to 500 characters.
Here's an example:
✗ curl https://my-domain-1234.twil.io/log-demo?arg=value
OK%
As you can see, Twilio Functions streamed the start, end and console.log output of my function into the Twilio console.
Monitoring for failures
If your Function returns an error in response to a Twilio Webhook then you will find this under the Debugger. Note: The debugger also supports searching by URL, so you could search for all errors/warnings relating to your function.
