An application comprises of multiple endpoints. Each endpoint has a name which is used in the URL. Which endpoint is requested is specified when the user calls the application.
Send Request to Endpoint
OpenEndpoints knows 2 types of data sources that can serve as input for the content transformation:
data that is transferred with the request, and
data that is loaded from other sources when the endpoint is executed in the background.
The following methods are available to transfer data with the request:
GET Request with parameters URL-encoded
POST Request containing parameters. This is the default when an HTML <form> is used. The default content type is application/x-www-form-urlencoded. Use multipart/form-data to add any number of file uploads.
POST Request with application type application/xml: In this case arbitrary XML is supplied (in the request body), which is passed to the parameter-transformation-input structure, inside the <input-from-request> element instead of the normal <parameter> elements.
POST Request with application type application/json: In this case arbitrary JSON is supplied (in the request body), which is converted to XML and passed to the parameter-transformation-input structure, inside the <input-from-request> element instead of the normal <parameter> elements. Note:
Any characters which would be illegal in XML (for example element name starting with a digit) replaced by _xxxx_ containing their hex unicode character code.
Note that if any JSON objects have a key _content, then a single XML element is created, with the value of that _content key as the text body, and other keys from the JSON object being attributes on the resulting XML element.
There are the following special request parameters:
Special parameters are supplied along with the normal parameters, apart from in the case of a POST request application/xml or application/json in which case these special parameters are passed as GET parameters
