Beta Release: This specification is a beta release. Endpoints, schemas, and behavior may change without notice.

The External Actions API enables:

• Asynchronous Processing - Adobe sends requests, you process them asynchronously
• Flexible Entity Types - Support for leads, accounts, and more
• Rich Data Mapping - Map Adobe data to your service fields
• Error Handling - Robust error reporting mechanisms
• Security - Multiple authentication options (API Key, Basic, OAuth2)

Start building your External Actions API service with the following documentation:

• Begin with OpenAPI Spec Requirements to define your OpenAPI spec.
• The Service Definition calls GET /getServiceDefinition. Returns capabilities, payload definitions, and split-path support.
• Execution Request sends POST /submitAsyncAction payload and responds quickly, then process asynchronously.
• The Callback Response receives callback at provided callbackUrl and returns activityData.
• Path Condition Accessors evaluates path conditions when split paths are enabled.
• Error Lifecycle Captures request and callback failures. See Error Handling
