GET /v1/payments — Look Up Payment by Reference

Use this endpoint to look up a payment using the merchant reference ID you assigned when creating it — for example, an order number. Unlike the Retrieve a Payment endpoint, which requires Accelebit’s internal payment UUID, this endpoint lets you query by your own identifier. The merchantRef query parameter is required; omitting it returns a 400 error. Payments are scoped to your merchant account — you can only retrieve payments created with your API key.

This endpoint requires the merchantRef query parameter. Requests without it will return a 400 INVALID_REQUEST error.
