MobilePay Subscriptions

One-Off Payments

You are able to:

• Create agreements with an initial payment.
• Request arbitrary one-off payments on an existing agreement.

Note: One-off payments are charged when the customer manually swipes accept or auto_reserve field was set to true when one-off payment was requested.

One-off payment does not affect the frequency and grace period. So if you create an agreement with a one-off payment, you can request the first subscription payment whenever you want. You can also request a one-off payment on an existing agreement in between two subscriptions payments, and it will not be affected by the frequency. When you create an agreement with a one-off payment, and the user accepts the agreement, the payment will be created and reserved.

Auto reserve

Merchants who wants to use auto_reserve field feature, must apply for this in regards to the onboarding of Subscriptions. Merchants cannot use this feature without being pre-approved to do so.

Request One-Off Payment With a New Agreement

Add a one_off_payment property to the POST /api/providers/{providerId}/agreements request payload if you want the agreement being activated only when the user is successfully charged an initial subscription amount.

Request parameters

In this case the response of POST /api/providers/{providerId}/agreements will contain additional one_off_payment_id value - id of the newly requested One-Off Payment.

{
  "id": "1b08e244-4aea-4988-99d6-1bd22c6a5b2c",
  "one_off_payment_id": "2a5dd31f-32c1-4517-925f-9c60ba19f8ca",
  "links": [
    {
      "rel": "mobile-pay",

    }
  ]
}

Request One-off Payment on an Existing Agreement

Use a POST /api/providers/{providerId}/agreements/{agreementId}/oneoffpayments endpoint in order to charge your customer one time for extra services.

{
  "amount": "80",
  "external_id": "OOP00348",
  "description": "Pay now for additional goods",
  "links": [
    {
      "rel": "user-redirect",
      "href": "https://example.com/1b08e244-4aea-4988-99d6-1bd22c6a5b2c"
    }
  ],
  "auto_reserve": true
}

One-off Payment will expire in 1 day if it is not accepted or rejected by the user during that time or automatic reservation failed and user didn’t take any action afterwards.

Request parameters

The response of POST /api/providers/{providerId}/agreements/{agreementId}/oneoffpayments contains two values: a unique id of the newly requested One-Off Payment and a link rel = mobile-pay.

{
  "id": "07b70fdd-a300-460d-9ba1-aee2c8bb4b63",
  "links": [
    {
      "rel": "mobile-pay",
      "href": "https://<mobile-pay-landing-page>/?flow=agreement&id=1b08e244-4aea-4988-99d6-1bd22c6a5b2c&oneOffPaymentId=07b70fdd-a300-460d-9ba1-aee2c8bb4b63&redirectUrl=https%3a%2f%2fwww.example.com%2fredirect&countryCode=DK&mobile=4511100118"
    }
  ]
}

• The id value can be used on the merchant’s back-end system to map a one-off payment with a specific Subscription agreement on the merchant’s side, and subsequently to capture a requested One-Off Payment when MobilePay user accepts it.
• The link rel = mobile-pay hyperlink reference must be used to redirect the user automatically using an HTTP response 302 or 303. Once the user is redirected, the MobilePay app will be opened to confirm the One-off Payment. This applies only if auto_reserve field is omitted or set to false.

When auto_reserve field is set to true:

Callbacks

Once the one-off payment status changes from Requested to Reserved, Rejected or Expired, a callback will be done to the callback address, which is configurable via PATCH /api/providers/{providerId} with path value /payment_status_callback_url. The same way as with callbacks for regular payment requests.

Callbacks about OneOff and Agreement

You will get callbacks about the payment to your callback address. Moreover, you will get callbacks about the agreement to either success or failure url, that you have set upon agreement creation. However, you will not get callbacks for either, before their status changes. So you should expect a callback when the agreement is accepted / rejected / expired and a callback when the OneOff is either accepted/rejected/expired.

Capture Reserved One-Off Payment

When you receive a callback about successfully reserved payment, now it’s time to capture your money. You can do that by making a call to POST /api/providers/{providerId}/agreements/{agreementId}/oneoffpayments/{paymentId}/capture endpoint. If the HTTP response is 204 - No Content, it means that the money was transfered to your account.

You can capture a payment only once for an order, and the payment can’t be more than the order’s authorized amount. This means that your customers can’t add to an existing order. If they want to add more products after an order has been placed, then they need to make a new order.

Cancel One-Off Payment Request/Reservation

In case you weren’t able to deliver goods or any other problem occur, you can always cancel one-off payment until it’s not captured or expired. You can do that by making a call to DELETE /api/providers/{providerId}/agreements/{agreementId}/oneoffpayments/{paymentId} endpoint. If the HTTP response is ‘204 - No Content’, it means that one-off payment request/reservation was canceled.

The enduserser cannot cancel the agreement with pending payment reservation, only the merchant can do so.

By cancelling the agreement with a pending payment reservation, then the merchant also automatically cancels the reservation

It is mandatory for the merchant to Capture or Cancel one-off payment if it was reserved on a customer account. It results in bad end-user experience, if the amount is reserved on the customer’s account for too long, without them receiving their product. It might also result in increased calls to support unit, which is to be avoided at all cost.
