PCI Proxy Use Cases
Note that this endpoint is also used by Datatrans to initiate payments. For PCI Proxy customers, most of the fields are not relevant. For an example, refer to this example.
A note on the payload
You may see in the payload example that the INT, ALP, EPS, WEC fields appear as required. You can safely ignore these fields for PCI Proxy use cases.
