Some Twilio webhooks require a response in *Twilio Markup Language* (TwiML) or JSON. The TwiML you send back to the webhook varies based on what product you are using: * [TwiML for Programmable Voice][] * [TwiML for Programmable Messaging][] * [TwiML for Programmable Fax][] Informational Twilio webhooks require a standard HTTP `200 OK` response. This shows that your web app received the webhook. ## Mock webhook requests for development Once you have identified the webhooks you are planning to use, it's time to write some code! For ad-hoc testing purposes during development, you may find it worthwhile to set up mock HTTP requests to your app. We suggest either using a command-line tool like [curl](https://curl.haxx.se/docs/manpage.html), or a desktop app like [Postman](https://www.getpostman.com/). Use the sample webhook requests found in the Twilio documentation as starters for your own requests, or send Twilio webhooks to a service like [RequestBin](https://requestbin.com/) to capture the HTTP request being sent. ## Create automated tests for webhooks After doing some initial validation of your code, you can write automated tests using your preferred testing framework. Once you deploy your app, you can check the Twilio Debugger for errors when a webhook is sent to your app. Those HTTP requests would make excellent candidates for additional tests for your web app framework. For test-driven development (TDD), you may consider swapping the order of this step and the previous step. ## Run your app on a public URL Twilio needs to send webhook requests to an internet-reachable URL. Choose from two methods: * Deploy your web app code to a development or test server on the public internet. * Expose a local environment to the internet using an HTTP tunneling tool like [ngrok][]. > \[!WARNING] > > Your network security team might block ngrok or other HTTP tunnels. In those cases, configure a development or testing server that Twilio can reach before deploying your webhook project to a production environment. To learn how to use ngrok to develop webhooks locally, see [Webhook testing][]. ### Configure your public URL with Twilio Configure your webhook target URL for Twilio requests in the Twilio ecosystem. * [Twilio Voice][voice-webhooks] might need a webhook URL for inbound voice calls, inbound messages, or inbound faxes. * [Twilio messaging][messaging-webhooks] might need a webhook URL for outbound messages. The typical API request parameter for the webhook URL gets named `callback` or `statusCallback`. To send an outbound message, the TwiML [``][twiml-msg] verb provides an attribute to set the status webhook URL. ### Validate that webhook requests come from Twilio Once Twilio can send requests to your web app, start validating that Twilio sends your incoming webhooks. To learn more, see [Webhooks Security][] specifically the [validating Twilio requests][] section. If your integration tests use your validation process, Update your integration tests, update the tests. Many test frameworks can set environment variables for test mode as well as production. Keep account credentials outside of your code as a best practice. ### Test your webhooks with live traffic To test live traffic depends on which webhooks you use, but you can start making phone calls to your Twilio number, sending text messages, or whatever else you have built. Try to exercise as many corner or edge cases as possible with your app. This checks any assumptions you left out of your unit or integration tests. ## Promote your web app to staging and production Promote your web app to a staging environment, then to production. At each step, update the webhook URL you use with Twilio for the correct environment. Test your webhook with SSL enabled and the certificates you use in production. Twilio webhooks don't work on HTTPS endpoints with self-signed SSL certificates. To learn more, see [Webhooks Security][]. Before passing production traffic through your web app, decide how Twilio should authenticate and sign the webhooks it sends you. The [Webhooks configuration API][config] sets the authentication at the URL level. ## Get answers If you have any concerns, see [Webhooks FAQ][].
