Cepter is a powerful and user-friendly Chrome extension that serves as a network requests interceptor, catering to the needs of web developers and testers. Its main objective is to streamline their workflow by allowing them to easily intercept network requests and modify their response body, status, or headers.

To start using Cepter, simply open the Chrome devtools side-panel and access the Cepter panel. From there, click on "connect to tab" to initiate the debugging process for the page you want to work on. Once connected, you can enable the "record network requests" feature to view all the network requests made to the page, whether through refreshing or interacting with it.

Creating an interception with Cepter is a breeze. You can either click on "add interception" or use an existing network request as a base for your interception. Give your new interception a name and select the interception type, with "Replace" being the commonly used option. For advanced users dealing with XHR JSON requests, the "Merge" option allows you to combine the body of the original response with the one you provide.

When creating an interception, you can choose a response method such as GET or POST and ensure that the URL regex pattern accurately matches the requests you want to intercept. To control the new response's status or body, you can edit the JSON. It's important to ensure that the JSON format of the response is valid in order to successfully save your changes.

Once you have created one or more interceptions, simply refresh the page or trigger the network requests you wish to intercept. Your changes will be applied according to the rules you have defined, allowing you to efficiently test and debug your web applications.
