PayGround Express Checkout API

PayGround's Express Checkout is a remote payment service that operates through PayGround's Mobile Payment system. It is designed to allow consumers to complete transactions quickly, using only their mobile number. Customers input their mobile phone number at the merchant´s checkout where the Express Checkout service is offered. PayGround then matches the mobile phone number with the customer's social security number, address, credit check, etc. using a series of look-ups. The customer chooses whether they would like to receive an invoice or to charge a debit or credit card. Thus, the payment does not end up on the usual mobile operator bill.

The Express Checkout system is integrated into the developer's online checkout process using SOAP or REST APIs. Although parts of the PayGround website are offered in English, much of the API documentation is provided exclusively in Swedish.
