JaSON
A simple, easy to use HTTP client to send API requests from within Chrome and see formatted, syntax highlighted responses.
Great for testing and debugging JSON and XML APIs, RESTful APIs, GraphQL APIs, web services, web applications and more.
Cookie support:
Automatically sends cookies from Chrome. This is extremely handy for APIs which require authentication. Simply authenticate via your browser as normal and JaSON will send cookies for requests which match.
HTTP methods:
GET, POST, PUT, PATCH, DELETE, HEAD, and OPTIONS
Dark/light theme:
Change the colour theme to suit your work environment.
Request history:
Keeps request history with full text search. Individual history items can be deleted, or marked as a "favourite" for easy access. History from previous versions of JaSON will be automatically migrated. Stores history in IndexedDB for improved performance.
Formatted input/output:
Provides an IDE like experience when editing request body and headers. Automatically formats request/response body syntax and colour based on content type.
Content type:
Supports JSON, XML, and form encoded data by default. Additional content types can be used by setting a custom content type header.
New and improved:
Completely re-written, new styling, layout, colours, additional features and improved performance.

I use this extension every single day, no kidding! It is simple and it works well. It formats the json response in a pretty format and when I copy the response it retains that nice formatting. The history is also extremely useful. I do not understand why google has now disabled this extension.
This extension provided exactly what I was looking for - the ability to test an API which responds to HTTP POST requests with JSON responses. One feature I love is that it remembers previous requests which makes it very easy to fire off an earlier request again or change the JSON body of the request and then do the same. Excellent!

Feels like it just needs a little more polish to get it to a 5-star rating, but overall it works very well.

It's a very simple interface, it should work without any problem but I cannot make it work. No matter how I try to create my json data the parameters don't seem to reach the php. So sorry because I really need this kind of tool.
cool.
Its OK, will be better if it could format the Json response in a more readable way (TreeView like an object).
Awesome - use it everyday.. well done.
Been using this for a couple of months now for all my JaSON based web services. Great Tool!
