# Register an HTTP Callout Action in a Flow

Automatically register an external service by declaratively defining an HTTP Callout action in Flow Builder.

### Required Editions

After you configure the HTTP callout action in a flow, Flow Builder auto-generates an external service registration, an invocable action, and Apex-defined types. You can then use the data output of the API request as input within Flow Builder and across Salesforce.
