Normalized Webhook JSON Response

Return a clean API response instead of a workflow-specific wrapper. The Set node normalizes the event, and JSON Output Mapper emits the mapped object at the top level when it is the only terminal node.

What this workflow does

  1. EventPayload accepts an incoming event body
  2. NormalizeEvent creates a small, predictable response shape
  3. ApiResponse returns plain JSON to the caller

Use cases

  • Webhook acknowledgement endpoints
  • Lightweight automation APIs
  • Adapters between two systems with different payload shapes

Setup

Replace the sample input with your webhook or API trigger, then update the Set and JSON Output Mapper mappings to match the fields your caller expects. Keep ApiResponse as the only terminal node when you need an unwrapped JSON body.

Notes

JSON Output Mapper is a terminal node. If you add another terminal Output node, Heym returns the normal label-keyed result shape instead of the mapped object at the top level.
