MoMo Pay Drop-in integration

Add MoMo Pay to an existing Drop-in integration.

On this page, you can find additional configuration for adding MoMo Pay to your Drop-in integration.

Before you begin

This page assumes you've already:

API reference

You don't need to send additional fields for MoMo Pay. To see optional fields that you can send for all payment methods, choose the endpoint you integrated:

/sessions: This is the default with Drop-in v5.0.0 or later.
/payments: If you implemented an advanced use case, or integrated Drop-in before v5.0.0.

Drop-in configuration

There is no MoMo Pay specific configuration for Drop-in.

Recurring payments

MoMo Pay supports recurring transactions. To make recurring transactions, you need to:

Create a shopper token.
Use the token to make future payments for the shopper.

Create a token

To create a token, include in your /payments request:

storePaymentMethod: true
shopperReference: Your unique identifier for the shopper.

When the payment has been settled, you receive a notification webhook containing:

eventCode: RECURRING_CONTRACT
originalReference: The pspReference of the initial payment.
pspReference: This is the token that you need to make recurring payments for this shopper.

Make sure that your server is able to receive RECURRING_CONTRACT as part of your standard notifications. You can enable the RECURRING_CONTRACT event code in the webhook settings page.

Make a payment with a token

To make a payment with the token, include in your /payments request:

paymentMethod.storedPaymentMethodId: The pspReference from the RECURRING_CONTRACT notification.
You can also get this value by using the /listRecurringDetails endpoint.
shopperReference: The unique shopper identifier that you specified when creating the token.
shopperInteraction: ContAuth

recurringProcessingModel: Use Subscription for a series of transactions following a fixed time interval or UnscheduledCardOnFile for contracts with non-fixed time interval.
