Using free tools, how can I modify/override a server response on the user-agent/client for any http method (e.g. POST/GET/DEL regardless of whether it is a fetch/XMLHttpRequest request)?

I have tried:

• Requestly browser extension, but it only handles fetch API/XMLHttpRequest requests
• HTTP Tookit but it does it on the fly only for paid PRO version
• Fiddler Everywhere but it needs to be bought (a trial period is not enough)

CodePudding user response：

Using Requestly Browser Extension, you can modify API responses (fetch/XHR requests) irrespective of HTTP Method. Demo

Using Requestly Desktop App, you can modify responses for any request type - JS, APIs, etc.
