Merchant initiated card payments

Card details can be tokenised to allow for the creation of merchant initiated payments. Merchant initiated payments can be useful in processing recurring payments such as subscriptions, or payments in instalments, without requiring the payer to repeatedly enter card details.

To enable merchant initiated payments:

Create a card token.
(For each subsequent payment) create a new payment request
use the 'paywithtoken' action to fulfil the payment request created in step 2.

Remember, when working with payment requests use a MERCHANT access token.

1. Generating a card token

Generating a card token is as easy as creating a payment request and setting the CardCreateToken field to true and the CustomerEmailAddress of the payer.

🚧
Customer Email Address
When creating and using a card token you must always ensure it's being used for the correct payer. The customer email address is the field that is used to associate a card token to a payer. It's up to you to ensure that any merchant initiated card payments use the correct token.

When the payer enters their card details to fulfil the payment request, a card payment response model is returned to the callback URL specified in the original payment request. The following field allows the creation of a merchant initiated transaction:

TokenisedCardID

Step 3 below shows how to use these fields when submitting a payment using a card token.

2. Creating subsequent payment requests

A new payment request must be created for each merchant initiated payment. These payment requests should be created as shown in creating and managing payment requests.

3. Submitting the payment

The card token payment can be submitted using the 'paywithtoken'. In the examples below:

TokenisedCardID is the value returned in step 1.
paymentRequestID is the ID of the payment request created in step 2.
