# Payment Method Setup Not Found

> The payment-method setup cannot be used by this customer

## Cause

The supplied setup does not exist or is not available to the authenticated customer. Unknown, tampered, and cross-customer setup identifiers intentionally return the same problem.

## Fix

Create and complete a new payment-method setup as the authenticated customer.

## Retry safety

Not retryable until the underlying state or request changes.

## Raised by

* [Create an appointment](/api-reference/appointments/create-an-appointment)
