HTTP Callout into Flow Builder Without Code

In Spring 23, Salesforce introduces the new HTTP Callout (Beta) element in the flow builder to do integration without code. Automate processes with external data by creating Flow Builder actions that call web-based service APIs using HTTP Callout. After you add the details of the API, Flow Builder generates a reusable action that you can use right away in Flow Builder and across Salesforce. Set up direct integrations as needed without code or a middleware service, such as Mulesoft.

HTTP Callout (Beta)

in Spring 23 release With the new HTTP Callout (Beta) button from the action element, we can now make calls to external web services. HTTP Callout can fetch data from an external system into Flow Builder without using code. We can set up direct integrations as needed without having to work with a developer.

HTTP Callout Demo

Before you configure an integration with HTTP Callout, you set up authentication in Setup > Named Credentials so that the external service can connect to the API.
