GCash for API only

Add GCash to an existing API-only integration.

Accept GCash 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 GCash 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 GCash integration:

  1. Make sure that you have set up your back end implementation.
  2. Add GCash in your test Customer Area.

Build your payment form for GCash

Include GCash in the list of available payment methods. You don't need to collect any information from the shopper in your payment form.

We provide logos for GCash 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:

The response contains paymentMethod.type: gcash.

Make a payment

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

  • paymentMethod.type: gcash
curl https://checkout-test.adyen.com/v52/payments \
-H "x-API-key: YOUR_X-API-KEY" \

The /payments response contains:

  • action.url: Link to where you should redirect your shopper.
  • action.method: GET or POST. The HTTP request method that you should use. After the shopper completes the payment, they will be redirected back to your returnURL using the same method.
    The redirect method depends on your payment method configuration and the length of the data included in the request, so make sure that your integration can handle both HTTP GET and HTTP POST methods.

To verify the payment result in the next step, you also need the following from the /payments response:

  • action.paymentData: The paymentData value that you send in your /payments/details request.
  • details: Array of parameters that you need to send in your /payments/details request. For example, payload or redirectResult.
    The parameters can vary based on the payment method configuration. Make sure to check the details array to confirm the parameters that you need to send in your next API request.
/payments response
{
   "resultCode":"RedirectShopper",
   "action":{
      "method":"GET",
      "paymentData":"Ab02b4c0!BQABAgCSZT7t...",
      "paymentMethodType":"gcash",
      "type":"redirect",
      "url":"https://test.adyen.com/hpp/skipDetails.shtml?brandCode"
   },
   "details":[
      {
         "key":"payload",
         "type":"text"
      }
   ],
   ...
}

Handle the redirect

To complete a GCash payment, you need to redirect the shopper to GCash's website.

  1. To complete the payment, redirect the shopper to the action.url returned in the /payments response.
  2. After the shopper is redirected back to your website or app, check the payment result by making a /payments/details request, specifying:
    • paymentData: Value you received in the /payments response.
    • details: Object that contains the URL-decoded values of the parameters that were returned when the shopper was redirected back to your website or app. For example, payload. To check the parameters that you should submit, refer to the details array that you received in the /payments response.
    /payments/details request
    {
         "paymentData":"Ab02b4c0!BQABAgCJN1wRZuGJmq8dMncmypvknj9s7l5Tj...",
         "details":{
           "{hint:Verify the parameters from /payments response}payload{/hint}":"Ab02b4c0!BQABAgCW5sxB4e/=="
         }
    }
    You receive a response containing:
    • resultCode: Use this to present the result to your shopper.
    • pspReference: Our unique identifier for the transaction.
    /payments/details response
     {
       "resultCode": "Authorised",
       "pspReference": "88154795347618C"
     }

For more information and detailed instructions, refer to Handling redirects.

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 GCash 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 GCash'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 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 notification webhook.
Refused The payment was refused by the GCash. 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 notification webhooks to know the outcome of the payment. The notification webhooks you can receive for GCash 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

GCash supports recurring transactions. To make recurring transactions, you need to:

  1. Create a shopper token.
  2. 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. If you have not requested for this additional configuration yet, contact our Support Team.

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

Test and go live

To test successful GCash live payments, you need to use a real mobile number registered with a GCash account.

If you are encountering issues with testing GCash payments, contact our Support Team.

Check the status of GCash test payments in your Customer Area > Transactions > Payments.

Before you can accept live GCash payments, you need to submit a request for GCash in your live Customer Area.
