The Hypertext Transfer Protocol (HTTP) 2xx class of status codes indicates that a client's request was successfully received, understood, and accepted. The 200 OK status code is the standard, most common response for successful HTTP requests. In the context of an API call made via an SAP API provider, a 200 OK response signifies that the API endpoint successfully processed the request and is returning the expected payload or acknowledgment.

A. 203: This is a success code (2xx), but it specifically means "Non-Authoritative Information," indicating the response is from a proxy, not the origin server. 200 is the direct and standard success code.

B. 403: This is a client error code (4xx) for "Forbidden." It means the server understood the request but refuses to authorize it, typically due to insufficient permissions.

D. 401: This is a client error code (4xx) for "Unauthorized." It indicates that the request lacks valid authentication credentials for the target resource.

"200 OK". This document defines the 200 OK status code as the standard response for a successful request. It is the authoritative source for HTTP standards

which SAP's products adhere to.

API Management > Monitoring APIs and Resources > API Analytics. The monitoring dashboards categorize HTTP response codes into classes (2xx

4xx

5xx). The 2xx codes are consistently grouped to represent successful calls

confirming the standard interpretation within the SAP ecosystem.

Cloud Integration > Defining an Integration Flow > Configure the HTTP Receiver Adapter. The documentation for handling responses from external systems specifies that a successful call typically returns an HTTP status code in the 2xx range

with 200 being the primary example.
