GoPay & QRIS

GoPay is an e-Wallet payment method by Gojek. Users will pay using the Gojek app. The user flow varies when using a Web Browser (on a computer) compared to a SmartPhone.

This API reference describes implementation of regular payment flow with GoPay and QRIS issued by GoPay. To implement GoPay Tokenizations in Snap, see this page.

By default, GoPay Deeplink and QRIS's transaction expiry is 15 minutes (min 20s, max 7 days).

📘

UI Mode

We will show either QRIS or Deeplink based on customer's screen size (wide screen will get QRIS, while small screen will get deeplink). Merchant can however specify whether GoPay will be shown in deeplink or QR format persistently using options.uiMode in Snap JS. UI Mode is specified to auto by default.

This guide will assume that the value of uiMode in Snap.JS options is auto, the recommended value.

When users make a purchase using GoPay on a Web Browser(on a computer)

1. Users see a QR code on their Web Browser
2. Users open the Gojek app on their phone
3. Users tap the Pay function on the Gojek app

4. Users point their camera to the QR Code

5. Users check their payment details on the Gojek app and then tap Pay

6. The transaction is complete and the users' GoPay balance is deducted

7. Midtrans will mark the payment_type of the transaction as qris. This will also impact the following:

• The JSON fields format (returned on Webhook/HTTP Notifications & Get Status API response) is "payment_type": "qris"

• The "payment_type": "qris" displayed on Midtrans Dashboard, and when you download transactions.

Implementing GoPay Deeplink Callback

In addition to the standard mobile apps flow, you can implement deeplink callback to redirect customer back from Gojek to your app.

📘

Prerequisites

E-commerce needs to prepare a deeplink which accepts two query parameters.

The steps to integrate with GoPay deeplink (Please look into the GoPay API Request for sample implementation) are given below.

1. Set enable_callback parameter in the api request to true.
2. Set callback_url with the deeplink URL redirecting to E-commerce apps via API request or configure it in Dashboard > Snap Preferences.
3. Handle redirection with above parameters.

For a full list of request body parameters please refer to the Request Body (JSON Parameter) section.

🚧

It is highly recommended to avoid using value passed on result to update status on backend. There is HTTP notification for this use case.
