When you build your application using Twilio API's, you may want to receive inbound HTTP(S) requests (also known as webhooks) from Twilio's servers. These webhooks contain information about events that have just occurred - for instance, a text message was sent to a Twilio phone number.
Some of these webhooks are informational (such as letting you know that a voice call recording is ready for download), and others require your web application to respond (for instance, letting Twilio know what to do when someone calls your Twilio phone number).
In all of these cases, you will need to tell Twilio what URL to send these webhooks to.

Each Twilio product uses webhooks differently. To learn more about which webhooks each product uses, and how to set them up with your application, visit these pages:
Webhooks aren’t just limited to products. You can also have Twilio send you webhooks when events occur in your application, such as billing levels reaching a certain threshold, or if an error occurs when Twilio calls your web application. You could setup a pipeline that sends your webhooks into Slack, Microsoft Teams, or another chat system. You could also set up a webhook that notifies you via email.
