Found an awesome Mac AppStore app that makes it easy to perform HTTP requests and see the response body.
From the website:
“With Graphical HTTP Client, you can send an HTTP request to a server, specify any number of headers, and examine the response body and headers. If the response is HTML, you have the option of opening that HTML up in a web view. You can also save the response as a file.”
It even formats JSON:
“If Graphical HTTP Client detects JSON as the response type, it will format it for you so you can easily view the response.”
Current available for £1.49 on the Mac AppStore.
