n8n Stripe Test Refund Workflow with Allowly Approval

Approve a Stripe test refund with Allowly—then generate proof evidence

This n8n workflow runs a Stripe test-mode refund only after an Allowly policy check permits it—or after a reviewer approval is confirmed through a secure callback. It then creates the refund in Stripe and retrieves the Allowly decision receipt as audit evidence.

What this workflow does

• Builds a structured refund request (manual start) including: Allowly authorization ID, Stripe PaymentIntent ID, amount, currency, reason, and a frozen resource string to bind the approval context.
• Validates request format, then reads the Stripe PaymentIntent via the Stripe API to confirm it is a succeeded test payment with sufficient captured funds.
• Requests Allowly authorization using the frozen resource and refund context via a refund.create decision check.
• Handles Allowly outcomes:
  • If Allowly allows immediately, it proceeds.
  • If confirmation/escalation is required, it waits for an authenticated HTTP callback, resolves the confirmation/escalation in Allowly, then performs a final Allowly re-check.
• Creates the Stripe refund (test-mode) using a Stripe idempotency key tied to the refund request ID, then validates the refund response.
• Fetches the Allowly receipt via the Allowly API to export refund evidence (marked pending if not yet signed).

Use cases

• Testing refund governance in a Stripe test environment with policy enforcement.
• Supporting a review-based approval flow where refunds are only executed after Allowly decisions (including escalation).
• Producing audit-ready evidence by exporting an Allowly receipt alongside each refund.

Technical details

• n8n nodes / logic: if, set, code, wait, n8n-nodes-allowlyallowly, sticky note
• Integrations: Stripe API (PaymentIntent verification, test-mode refund creation) and Allowly API (refund.create decision + receipt retrieval)
• Setup requirements: add Stripe test credentials and Allowly API credentials, and use the same Stripe credential for both Stripe HTTP requests; configure Allowly nodes and the receipt-fetching HTTP request.
