Make an HTTP request

You can define a workflow step that makes an HTTP call and assign the response from the call to a variable. For example, you can invoke a Google Cloud service such as Cloud Run functions or Cloud Run through an HTTP request.

Invoking a Google Cloud service through an HTTP request shouldn't be confused with using Workflows connectors to perform API operations. Connectors simplify calling services because they handle the formatting of requests for you, and provide methods and arguments so that you don't need to know the details of a Google Cloud API.

Invoke an HTTP endpoint

This type of step lets you make an HTTP request. Both HTTP and HTTPS requests are supported. The most common HTTP request methods have a call shortcut (such as http.get and http.post), but you can make any type of HTTP request by setting the call field to http.request and specifying the type of request using the method field.
