The HTTP 201 Created success status response code indicates that the request has succeeded and has led to the creation of a resource.
Use HTTP status code 200 for successful requests that retrieve or update a resource. Use HTTP status code 201 for successful requests that create a new resource on the server. Use HTTP status code 202 for requests that have been accepted for processing but the processing has not yet been completed.
a 201 response is for when the request specifically creates something and does not have a response body; and. a 204 response is for when the request succeeds but has no body to return.
The 201 (Created) status code indicates that the request has been fulfilled and has resulted in one or more new resources being created. The primary resource created by the request is identified by either a Location header field in the response or, if no Location field is received, by the effective request URI.
201: “Created.” The server has fulfilled the browser's request, and as a result, has created a new resource. 202: “Accepted.” The server has accepted your browser's request but is still processing it. The request ultimately may or may not result in a completed response.
201: For a successful request and data was created. 204: For empty response. 400: This is used for Bad Request. If you enter something wrong or you missed some required parameters, then the request would not be understood by the server, and you will get 400 status code.
It is perfectly acceptable to specify a response body and use the Location header at the same time. When using the Location header with a 201 response, you're not redirecting the client, you're just telling it where it can find the resource in future. Redirects only apply to 3xx responses.
Accepted 202
The request has been accepted for processing, but the processing has not been completed. The request may or may not eventually be acted upon, as it may be disallowed when processing actually takes place. there is no facility for status returns from asynchronous operations such as this.
The HTTP 204 No Content success status response code indicates that a request has succeeded, but that the client doesn't need to navigate away from its current page. This might be used, for example, when implementing "save and continue editing" functionality for a wiki site.
Perhaps the most common status code returned is 200. It simply means that the request was received, understood, and is being processed, whereas the 201 status code indicates that a request was successful and a resource was created as a result.
The HTTP 200 OK success status response code indicates that the request has succeeded. A 200 response is cacheable by default. The meaning of a success depends on the HTTP request method: GET : The resource has been fetched and is transmitted in the message body.
What is the 201 HTTP Status Code? The 201 HTTP status code indicates that a new resource has been created. The server returns the link of that newly created resource in the response body.
2 201 Created. The request has been fulfilled and resulted in a new resource being created. The newly created resource can be referenced by the URI(s) returned in the entity of the response, with the most specific URI for the resource given by a Location header field.
The 204 (No Content) status code indicates that the server has successfully fulfilled the request and that there is no additional content to send in the response payload body. While 200 OK being a valid and the most common answer, returning a 204 No Content could make sense as there is absolutely nothing to return.
The difference between POST and PUT is that PUT requests are idempotent. That is, calling the same PUT request multiple times will always produce the same result. In contrast, calling a POST request repeatedly have side effects of creating the same resource multiple times.
The HTTP 203 Non-Authoritative Information response status indicates that the request was successful but the enclosed payload has been modified by a transforming proxy from that of the origin server's 200 ( OK ) response.
The HTTP 205 Reset Content response status tells the client to reset the document view, so for example to clear the content of a form, reset a canvas state, or to refresh the UI.
404 is a status code that tells a web user that a requested page is not available. 404 and other response status codes are part of the web's Hypertext Transfer Protocol response codes. The 404 code means that a server could not find a client-requested webpage.
With a 200 code, you know for sure that the request was accepted and processed. However, a 202 indicates that while the request was accepted, the processing has not been completed or hasn't even started yet.
APIs, always have to return 200 except 500. Because when the server dies, it can't return anything.
The Location response-header field is used to redirect the recipient to a location other than the Request-URI for completion of the request or identification of a new resource. For 201 (Created) responses, the Location is that of the new resource which was created by the request.
A 500 Internal Server Error is an HTTP status code that indicates that the server encountered an unexpected error while processing the request. Note: Reach out to the API service and check the status page of the API Service and see if their systems are operational.
A 503 Service Unavailable Error is an HTTP response status code indicating that a server is temporarily unable to handle the request. This may be due to an overloaded server or a server that's down for maintenance.
HTTP response status code 201 Created indicates that data was received and saved as a new resource on the server, and that the HTTP request did not overwrite or update existing data on the server.
