Direct connect architecture with collana pay

The integration of collana pay offers two available options. The sales process is the same for both options. However, communication is handled differently.

The direct connection requires a webshop integration, which enables a seamless connection to collana pay. With the direct connection, the webshop receives the transaction ID generated by collana pay, which is transferred to the ERP system after the order process has been completed. This enables the ERP system to carry out a status request.

If the amount or part of the amount is to be refunded, the refund endpoint can be used. The money is then credited back to the customer via the PSP.

Example: The customer does not want to keep the received goods and returns them. The return is received and after successful verification of the goods, the money is credited to the customer.
