Merchant Initiated Transaction

A merchant initiated transaction is a payment that is agreed with payer's concent, and is initiated by the merchant collecting the payment.

In order to apply for a merchant initiated transaction, the merchant need to specify why this transaction is initiated, as well as the authorization_tracking_id of the original transaction, and stored_credential_indicator to show if it's the first card on file transaction on the subsequent one.

You can see different reasons here.

A Merchant Initiated Transaction Example

In order to apply a merchant initiated transaction, the customer will need to put their card on file first.

This transaction can be a zero dollar authorization just to put card on file, or it could be the initial payment customer is required to pay. We will assume customer is just doing a zero dollar authorization. We can create the transaction via Create a purchase .

Note that since we are putting card on file, we will need to specify card_on_file to true.

/* 
 * Request: POST /v1.0/purchases
 */
{
  "amount": 0,
  "currency": "AUD",
  "card_holder": "John Smith",
  "card_number": "411111xxxxxx1111",
  "card_expiry": "01/2025",
  "cvv": "123",
  "reference": "customer_initiated_transaction",
  "extra": {
    "card_on_file": true,
    "stored_credential_indicator": "I"
  }
}

In the response, we will get the card_token as well as the authorization_tracking_id. These values will need to be stored for the merchant initiated transaction later.

To apply for a merchant initiated transaction, you need to apply the card_token, the auth_reason and authorization_tracking_id in the payload.

Note: Not all schemes requires authorization_tracking_id. If this value is not found in the response, then it indicates this scheme does not support it, and this can be ignored for subsequent transactions.

❗️
Failure to present the authorization_tracking_id may result in the recurring or installment transaction being declined, particularly wallet transactions.
