Behavior

Behavior Modes

Mode	Condition	Result
Full trigger + effect test	Valid hook and mock data payloads	Runs trigger, then each effect sequentially, returns ordered result array.
Early return	Effect returns no params payload	Returns accumulated results immediately.

Impact on Other Data

This endpoint does not insert/update/delete hook documents.

Operational Considerations

• Complex effects can make test runs slow because effects are executed sequentially.
• Some effect types perform real outbound actions during test execution (for example HTTP requests or emails), depending on effect implementation and environment.

Limitations

• mock_data parsing errors are surfaced through the generic 503 Hook test failed... branch.
• Validation for effect configuration is strict for HTTP effects and loose for non-HTTP effects.
