What is an HTTP POST request?

An HTTP POST request sends data to a server inside the message body rather than in the URL. The body has no practical size limit, it does not land in server access logs or browser history, and browsers do not cache the response. That is what separates POST from GET.

POST is not idempotent: sending the same POST twice usually creates two records. PUT is idempotent — it replaces a resource at a known address, so repeating it changes nothing. Use POST to create, PUT to replace.

What does a POST request consist of?

Three parts: the request line, the headers, and the body. The request line names the method, the path, and the HTTP version. Content-Type tells the server how to read the body, and Content-Length gives its size in bytes.

POST /api/orders HTTP/1.1
Host: example.com
Content-Type: application/json
Content-Length: 42

{"customer": "Jason Sweet", "quantity": 1}

ReqBin builds this request for you: enter the URL, select POST, put the body on the Content tab, and pick the Content-Type. Both the raw request and the server's raw response are shown.

How do I post requests online?

To send a GET request to the server, simply enter your URL, select the GET method from the dropdown list, and click Send. If your request requires authorization, enter your credentials on the Authorization tab. To make a POST request online, select the POST method from the dropdown list and enter the POST data on the Content tab. Here you can also select Content-Type for your POST data.

Can I send HTTP requests to local endpoints?

Yes, you can post HTTP requests to local endpoints (localhost and 127.0.0.1) and servers on your local network using the ReqBin online HTTP client. To do this, you need to add the ReqBin Google Chrome Extension to your browser using this link.

Will I have CORS issues when sending requests to my server?

No, you won't have CORS (cross-origin) issues when sending requests to your server, and you won't need to make any changes to your server code such as adding the Access-Control-Allow-* HTTP headers. You can post requests to your server directly from your browser without any additional action!
