The requirement is to integrate with a REST API that expects "form encoded" parameters. This refers to the standard data submission format used by web forms, specifically the application/x-www-form-urlencoded content type. This encoding scheme is defined within the HTML specification. Therefore, registering the service as an "HTML Form" type is the most precise and accurate choice, as it directly corresponds to the specified data encoding standard. This type correctly signals that the integration will format request parameters as key-value pairs, identical to a standard HTML form submission.

"Form content types": This official W3C recommendation defines the application/x-www-form-urlencoded media type as the default content type for HTML form submissions. It specifies the encoding rules for form data sets

which is the standard for "form encoded" parameters.

"Representational State Transfer (REST)": This dissertation

which defines REST

distinguishes it from other architectural styles. It clarifies that REST is protocol-independent but in practice

on the web

it leverages HTTP standards

including data encoding types like application/x-www-form-urlencoded defined for HTML.

Lecture 15 Notes: These course materials discuss HTTP requests

including POST requests with form data. They explain that data is sent as "a string of key=value pairs separated by &

" which directly describes the application/x-www-form-urlencoded format originating from HTML forms.
