Sending data to the API

Sending data to the API can be done by setting HTTP headers, request parameter or as a JSON structure in the request body.

Accessing data in a valve is done by using expansion.

Example

Given the http request with body:

{
	"firstkey": "fistvalue",
	"secondkey": "secondvalue"
}

Using expansion in valve to access "firstkey" is done through ${request.firstkey}.

Lets say the request sent in something in the http header Authorization header.

Expanding data in the Authorization haders is done: ${request.header_firstkey}.

Note the "header_" prefix.
