Original Pull Request: https://github.com/langgenius/dify/pull/24874

State: closed
Merged: Yes

This commit adds variable management to the webhook trigger node, enabling automatic synchronization of input parameters, headers, and body parameters as workflow variables.

Key features:

  • Automatic variable creation from webhook parameters, headers, and body fields
  • Real-time synchronization when parameter configurations change
  • Duplicate variable name detection with user-friendly error messages
  • Clean architecture with reusable sync logic to eliminate code duplication

Technical changes:

  • Added TriggerWebhook to SUPPORT_OUTPUT_VARS_NODE for variable system integration
  • Implemented formatItem case for TriggerWebhook node variable processing
  • Enhanced WebhookTriggerNodeType with variables field
  • Created syncVariablesInDraft helper for consistent variable management
  • Added proper error handling and validation for variable conflicts
