Free REST API Debugging Tools
Think of this website as the JsFiddle for RESTful APIs.
The ApiRequest.IO website lets you send sequence of HTTP requests to an API for testing and debugging. The request/response history is saved under a unique URL for 30-days that can be shared with your teammates or when getting help on forums like Stack Overflow.
This Chrome extension lets you capture AJAX HTTP requests/responses made to an API from many websites such as from a React single-page app.
The requests and responses are saved in a workspace for 30-days so you can share the captured JSON with teammates and resend the same requests. Think of it as the network tab from Chrome Developer Tools but on steroids. Each recorded workspace has a shareable link just like sharing a Google Doc.
This Chrome extension allows you to send cross-domain requests directly from browser without receiving Cross Origin Errors. You can override the Request Origin header with this plugin and also have Access-Control-Allow-Origin set set to *.
Allows you to override on any website:
Request Headers: Origin
Response Headers: Access-Control-Allow-Origin, Access-Control-Allow-Methods, Access-Control-Allow-Headers, Access-Control-Allow-Credentials
For understanding Cross Origin Resource Sharing (CORS), check out the Guide to CORS for REST APIs and common pitfalls.
