https://api.sandbox.cleeng.com/3.1/passes
This endpoint returns passes that match the specified criteria (transactionId, paymentMethodId, externalId, customerId or offerId and customerId together). Please bear in mind that if you don't provide any parameters, an empty list will be returned.
Note: Filtering by customerId and offerId might return multiple active passes instead of one if multiple passes have been created for the same offer.
