GoPay for API-only

Add GoPay to an existing API-only integration.

Accept GoPay payments using our APIs, and build your own payment form to have full control over the look and feel of your checkout page.

Before you begin

These instructions explain how to add GoPay to your existing API-only integration. The API-only integration works the same way for all payment methods. If you haven't done this integration yet, refer to our API-only integration guide.

Before starting your GoPay integration:

Make sure that you have set up your back end implementation.
Add GoPay in your Customer Area.

Build your payment form for GoPay

Include GoPay in the list of available payment methods.

We provide logos for GoPay which you can use on your payment form. For more information, refer to Downloading logos.

If you are using the /paymentMethods to show available payment methods to the shopper, specify the following:

countryCode: Any supported country. For example, ID.
amount.currency: Any supported currency. For example, IDR.
amount.value: The value of the payment, in minor units.
channel: Specify Web, iOS, or Android.

The response contains paymentMethod.type: gopay_wallet.

Make a payment

From your server, make a /payments request, specifying:

paymentMethod.type: gopay_wallet

Additionally, you must include either of the following:

browserInfo: Information about the shopper's browser.
channel: Web.

The /payments response contains an action object with the information needed to redirect the shopper.

Handle the redirect

To complete a GoPay payment, you need to redirect the shopper to the GoPay website or app.

To complete the payment, redirect the shopper to the action.url returned in the /payments response.

When using the HTTP GET method:
For security reasons, when displaying the redirect in the app, we recommend that you use SFSafariViewController for iOS or Chrome Custom Tabs for Android, instead of WebView objects. Also refer to the security best practices for WebView.

After the shopper is redirected back to your website, check the payment result by making a POST /payments/details request, specifying:
- details: Object that contains the URL-decoded redirectResult returned when the shopper was redirected back to your site.

You receive a response containing:

resultCode: Use this to present the result to your shopper.
pspReference: Our unique identifier for the transaction.

Present the payment result

Use the resultCode that you received in the /payments/details response to present the payment result to your shopper.

The resultCode values you can receive for GoPay are:

resultCode	Description	Action to take
Authorised	The payment was successful.	Inform the shopper that the payment has been successful.
Cancelled	The shopper cancelled the payment while on GoPay's website.	Ask the shopper whether they want to continue with the order, or ask them to select a different payment method.
Error	There was an error when the payment was being processed.	Inform the shopper that there was an error processing their payment. The response contains a `refusalReason`, indicating the cause of the error.
Pending or Received	The shopper has completed the payment but the final result is not yet known.	Inform the shopper that you've received their order, and are waiting for the payment to be completed. To know the final result of the payment, wait for the AUTHORISATION webhook.
Refused	The payment was refused by GoPay.	Ask the shopper to try the payment again using a different payment method.

If the shopper closed the browser and failed to return to your website, wait for webhooks to know the outcome of the payment. The webhooks you can receive for GoPay are:

eventCode	success field	Description	Action to take
AUTHORISATION	false	The transaction failed.	Cancel the order and inform the shopper that the payment failed.
AUTHORISATION	true	The shopper successfully completed the payment.	Inform the shopper that the payment has been successful and proceed with the order.
OFFER_CLOSED	true	The shopper did not complete the payment.	Cancel the order and inform the shopper that the payment timed out.

Recurring payments

GoPay 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 (minimum length three characters).

When the payment has been settled, you receive a 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 webhooks. You can enable the RECURRING_CONTRACT event code in the webhook settings page.

Make a payment with a token

To make a recurring with a token, make a /payments request and include:

paymentMethod.storedPaymentMethodId: The shopper's payment token.

You can also get this value by using the /listRecurringDetails endpoint.
shopperReference: Your unique identifier for the shopper.
shopperInteraction: ContAuth.
recurringProcessingModel: Subscription.
