Paymentology’s Physical & Virtual Debit Card Issuance API

Companion API is a simple API that allows you to issue cards and hold your customers’ card balances on your platform

A Companion card is a card that is linked to a store of value (SVA) like a wallet or a bank account. What makes this API different from the others we offer, is that the customer’s card balance sits within the SVA and not on the card. Choose the Companion API if you want to issue cards and hold your customers’ card balances on your own platform.

With this API, you can issue physical and virtual prepaid cards linked to a separate SVA. Cards are linked to the SVA, so whenever transactions are made, the SVA is debited.

Note: You’ll be responsible for authorising transactions with this API.

If you want Paymentology to hold your customer’s balance for you, use the Card API instead. If you’re not sure which API to choose, read about our APIs first or get in touch.
