Validate SeaTable Webhooks with HMAC SHA256

# Validate Seatable Webhooks with HMAC SHA256 Authentication ## Overview Automated workflow: Validate Seatable Webhooks with HMAC SHA256 Authentication. This workflow integrates 7 different services: webhook, stickyNote, respondToWebhook, stopAndError, if. It contains 13 nodes and follows best practices for error handling and security. ## Workflow Details - Total Nodes: 13 - Node Types: 7 - Error Handling: ✅ Implemented - Security: ✅ Hardened (no sensitive data) - Documentation: ✅ Complete ## Node Breakdown - 200: respondToWebhook - 403: respondToWebhook - Calculate sha256: crypto - Seatable Webhook: webhook - Add nodes for processing: noOp - hash matches: if - Sticky Note: stickyNote - Error Handler: stopAndError - Stopanderror 1: stopAndError - Stopanderror 2: stopAndError - ... and 3 more nodes ## Usage Instructions 1. Configure Credentials: Set up all required API keys and credentials 2. Update Variables: Replace any placeholder values with actual data 3. Test Workflow: Run in test mode to verify functionality 4. Deploy: Activate the workflow for production use ## Security Notes - All sensitive data has been removed or replaced with placeholders - Error handling is implemented for reliability - Follow security best practices when configuring credentials ## Troubleshooting - Check error logs if workflow fails - Verify all credentials are properly configured - Ensure all required services are accessible
