Partner Integration

Partner Code:

Please note that each partner will be assigned a three-letter word by Merrco Payfirma (please ask us if you require one).

To tag all transactions originating from your application, please send your assigned three-letter word

in the custom_id field in the sales request packet. This identifying word will help us to reconcile all data for

merchants using your application.
