The HTTP/2 binary framing mechanism has been designed to not require any alteration of the APIs or config files applied: it is broadly transparent to the user. this you need to prepare in transform message and then use HTTP requestor and there in payload section pass the value as below output multipart / form - data payload Kudos for accurately calling out KISS, @AkshayHiremath He's referring to the fact that you might be sending something else in the body, e.g. If we are using POST/PUT API, then based on the REST API contract, we should send the whole resource information because these methods work on the whole resource. For example, if we are creating a REST API to update student details using PUT (HTTP Method), then the request URI will be{server_host}/students/{student_id},and the requestbody would be: I have seen that many times, developers get confused about why we need to send the same parameter to multiple places. The difference between PUT and POST is that PUT is idempotent: calling it once or several times successively has the same effect (that is no side effect), whereas successive identical POST requests may have additional effects, akin to placing an order several times. To make an HTTP OPTIONS request, given an HttpClient and a URI, use the HttpClient.SendAsync method with the HttpMethod set to HttpMethod.Options: The TRACE request can be useful for debugging as it provides application-level loop-back of the request message.

A reasonable takeaway to your above analysis is that idempotent operations are best kept in the url query strings and CRUD is best kept to strictly typed response bodies, which essentially takes advantage of SOP and prevents very basic forms of social engineering/phishing attacks. If transfer encoding is not used, the payload body and message body are the same! A representation (data and metadata) is transferred as a single or multiple messages, so a message encloses a complete or partial representation.
