What status code is returned in the request when successful?

In the context of web services and APIs, a status code of 200 indicates that a request was successful and that the server has returned the data that was requested. This status code is part of the HTTP response status codes, which are used to indicate the outcome of a request made to a server.

A 200 status code confirms that the client's request was properly received, understood, and processed. It's important for integration architects to ensure that their systems communicate effectively with external services and that they can handle responses appropriately. When the system receives a 200 status code, it signifies that everything is functioning as intended, allowing for appropriate next steps in the integration process.

In contrast, the other status codes indicate different issues. A 400 status code represents a bad request, meaning there was something wrong with the request syntax. A 404 status code means that the requested resource could not be found, and a 500 status code indicates an internal server error, highlighting a problem on the server side that prevented the request from being completed successfully. Each of these codes signals a failure or an issue that would require further investigation or corrective actions.
