Instead of adding the data directly to the command line you can instruct cURL to upload a file as the body. The previous example can get unwieldy quickly as the size of your request body grows. $ curl -H 'Content-Type: application/json' -d '' POST with a file as the body This cURL command sends JSON in the body by using -H 'Content-Type: application/json' to set the appropriate HTTP header. Many APIs expect data formatted in JSON or XML instead of encoded key=value pairs. The following submits data the same as if a web form were used (default Content-Type: application/x-$ curl -d "key1=some value&key2=some other value" POST with JSON body Much more useful is making POST requests. These tutorials provide some easy to follow examples and the man page has all the gory details. cURL can make just about any request, assuming you can figure out how. As a command line tool some developers will balk at using it, but cURL’s simplicity and portability (nix, pc, mac) make it an appealing tool. The venerable cURL is possibly the most flexable while at the same time being the least usable. They both offer built in consoles that provide network information like headers and cookies. Chrome also has a version of JSONview and for XML there’s XML Tree. To see the response headers LiveHTTP Headers will do the trick. To see similarly formatted JSON there is an extension called JSONView. Firefox users already get nicely formatted XML. Some browsers don’t necessarily present the response in a format easily readable by humans. At our developer portal we embed sample URLs in our documentation were possible to make seeing examples super easy for developers. Yes a web browser can be a tool for experimenting with APIs, so long as the API request only requires basic GET operations with query string parameters.
