We use these tools all day every day when working with our REST API. They make things easy for us, and we think they could help you as well.
This extension formats all JSON in a nice and readable manner. But the absolute best thing is that it makes all links clickable. If you just want to start exploring our API without having to register or set up authentication, then just install this extension, go to https://rest.reviso.com?demo=true and follow the links. This by far the most powerful tool when exploring our API.
This tool makes it easy to send requests to our API, and inspect the response. Just add your headers and start GET'ing and POST'ing.
When you don’t have the luxury of the Chrome Developer Tools and need to debug your own application, then Fiddler is absolutely one of the best tools out there. Head on over to Telerik and download it.
