What Is UUID Payment ID?

The UUID payment ID is created once and referenced by every subsequent event — capture, refund, dispute — so nothing gets misattributed.
It pairs with the idempotency key from the initial charge request.

How to generate

Generate a v4 UUID at charge time.
Persist it as the payment record key.
Echo it in every webhook payload you send/receive.

Use Cases

Stripe-like charges.
Marketplace payouts.
Dispute evidence bundles.

Code Examples

JavaScript

const id = crypto.randomUUID();

Python

import uuid
id = uuid.uuid4()

Frequently Asked Questions

Payment ID in webhooks?

Yes — include it so your endpoint can idempotently process the same event delivered twice.

One payment ID per attempt or per order?

Per attempt; a retried charge is a new attempt with a new id but the same idempotency key.
