πŸ“˜ Description

This workflow automates payment-related customer support escalation by validating reported issues against transaction data and coordinating all downstream actions in a controlled, auditable way. It is designed for support teams that need to quickly separate valid payment failures from false or incomplete reportsβ€”while maintaining consistent customer communication and timely human intervention.

The workflow is triggered via a webhook whenever an external system reports a customer issue. Incoming data is normalized and cross-checked against Google Sheets, which acts as the single source of truth for transaction status, payment confirmation, and order creation. An AI escalation engine then applies strict, rule-based logic to determine whether the issue is confirmed, needs clarification, or not valid, without assuming or inventing missing information.

For confirmed cases, the workflow runs parallel actions: it generates a concise escalation summary for human support, logs full context to Slack, creates a Zendesk ticket for traceable resolution, and sends a calm, customer-safe email acknowledging the issue. Transaction records are then updated to reflect confirmation status. Robust error handling ensures any workflow failure is immediately surfaced in Slack.
