Ejemplo de recibo genérico

Openpay offers the possibility of retrieving a generic payment slip with the necessary information so your customer can complete their bank transfer successfully. To retrieve it, you need to create an URL with the following structure:



Production {DASHBOARD_PATH} =

{MERCHANT_ID} = your merchant id
