This method allows you to pay multiple bills that were found using an address search.

7.1 Saving a card

7.1.1 Obtaining credentials

It is necessary to make a POST request with the parameters of the user's login and password to receive credentials

https://www.portmone.com.ua/r3/api/merchant-bills

Request structure and example:

        }

        if bill != nil {
            let mask = bill?.cardMask ?? ""
            let token = bill?.token ?? ""

Testing

After registering in the Portmone.com system, you need to get the following information from your Account manager:

the ID of your company in the Portmone.com system (payee_id);
your company's private key – a value that you will use to create a unique signature of each request.

The Portmone.com system provides partners with two modes for testing: test mode and production mode with an automatic payment cancellation.

The test mode of the payment gateway means that the Portmone.com system checks the validity of entered data from the Partner and its Client, creates an order, but payment card authorization is not performed. 3-D Secure check is not possible.

Cards for testing:

Card number	Result
4444333322221111	Successful payment
4111111111111111	Failed payment

The production mode with payment auto cancellation provides the possibility to make real payments using real payment cards. The cancellation of payment is performed automatically within 30 minutes.

Please contact our Account Managers to enable and disable test mode or payment auto cancellation

Email: [email protected]

Important! Before putting the payment acceptance system into operation, make sure that the test mode or payment auto cancellation are disabled!
