Debugging your application

Twilio provides several tools for investigating the interaction between your application and Twilio, including the Debugger, Alerts, and Request Inspector in our Project Console site. These tools allow developers can use to quickly see how well their application is performing. 


The Debugger contains a detailed log of activity within your application. This log can help you dive deeper and and understand what Twilio resources were impacted and by whom. A detailed log, such as the one exposed via Events can be useful in understanding the root cause of a problem. 



Alerts are flagged on specific Twilio requests that generate an error or warning. Calls and Messages with alerts are highlighted in red, making them easy to spot in your Call Logs and SMS Logs.

Clicking the timestamp of an alerted call or message will give you a more details view of the alert flagged.

Request Inspector

The Request Inspector lists all requests made between Twilio and your application for a call. To view the Request Inspector, just access your Call Logs, and click a recent call (Request inspector data is kept for 30 days after the call was created).


You can also use the Request Replay feature to replay a request and see a side-by-side difference between the saved request and the new request.  The replayed request is identical to the original; Twilio will send all the same header and request information.
