Request Breakpoints

How many times have you wanted to stop before sending an API call or just try to understand where the API call is initiated and the context at the time? This is a very common need when working with sites that have many API requests.

Luckily, the devtools have a way to debug it.

• In sources panel, there is a section named XHR/fetch breakpoints
• Adding URL(s) to this section will pause the execution before a call to those added urls are invoked

PS: URLs doesn’t need to be of full length. A part of the URL will also be matched.

Try

1. Open sources tab in devtools
2. In the right pane, find XHR/fetch breakpoints section below breakpoints section
3. Add the URL demo to it using the + icon
4. Click on the button below initiate an XHR request to the above URL
5. Refresh the page and try again to ensure the overrides are saved
