Sending a PATCH Request with Curl [Python Code]

To send a PATCH request using Curl, you need to 1) tell Curl to send a PATCH request by specifying the -X PATCH command line parameter, 2) pass the PATCH data with the -d command line parameter, and 3) provide the correct ContentType HTTP header with the -H command line parameter. The -X PATCH command line parameter tells Curl to use the HTTP PATCH method instead of POST. The -H 'Content-Type: application/json' command line parameter tells Curll to send an HTTP header to the server, indicating the data type in the PATCH message's body. In this Curl PATCH Request Example, we send a PATCH request to the ReqBin echo URL using the -X command-line option. Click Run to execute the Curl PATCH Request online and see the results.

What is Curl?

Curl is a command-line utility for transferring data to or from a remote server. Curl is used for API testing, sending files to the server, and viewing the server response headers. Curl supports over 25+ protocols, including HTTP, HTTPS, FTP, FTPS, and SFTP, has built-in support for SSL certificates, HTTP Cookies, and more.

What is HTTP PATCH?

The PATCH method is one of 9 commonly used Hypertext Transfer Protocol (HTTP) request methods to modify an existing resource partially. The PATCH method sends an object containing partial data and rules for applying this data to an existing resource identified by its URI. For a PATCH request, we don't need to provide all the data. We only send the data that we want to update. The main difference from the HTTP PUT method is that the HTTP PATCH method partially replaces the resource, while the HTTP PUT method completely replaces the resource. PATCH is somewhat similar to the concept of "update" in CRUD.

Curl PATCH Request Syntax

The general form of the Curl command for sending a PATCH request is as follows:

Curl PATCH Request Syntax
