Google Pay on Android without the SDK
It is possible to use Google Pay without the SDK.
About this integration
Even without the Android SDK, there is only minimal configuration required to get set up to process Google Pay. Unlike some other integrations it does not require you to sign up for a Google Developer account.
Enable Google Pay
To enable Google Pay, head over to your dashboard and then go to Connections -> Catalog -> Google Pay.
Next, fill in your merchant name and the domain name(s) where you want to use Google Pay.
Integrate Google Pay
To learn how to integrate Google Pay we recommend following Google’s tutorial. The steps below will highlight any differences and specifics for our API.
Set gateway and merchant ID
In step 2 of Google’s tutorial you are instructed to request a payment token for your provider.
In our case, the value for gateway
needs to be set to gr4vy
, and the value of gatewayMerchantId
needs
to be set to app.gr4vy.sandbox.[gr4vy_id].[merchant_account_id]
for your sandbox environment, and
app.gr4vy.[gr4vy_id].[merchant_account_id]
in production.
The Gr4vy ID is the unique identifier for your instance. Together with the environment (sandbox or production) it is used to connect to the right APIs.
The possible values for your ID are one of wpay
, wpay1
, wpay2
, or wpay3
. We will inform you
in which instance your account has been set up.
Create a transaction
In step 9 of Google’s tutorial, you will have a paymentData
that needs to be
sent to the gateway. You can send this object to our POST /transactions
endpoint.
curl -X POST http://api.sandbox.example.gr4vy.app/transactions \
-H "Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIi..." \
-H "Content-Type: application/json" \
-d "{
"amount": 1299,
"currency": "AUD",
"country": "AU",
"payment_method": {
"token": paymentData.paymentMethodData.tokenizationData.token,
"card_suffix": "1234", # Can be extracted from paymentData.paymentMethodData.info.cardDetails
"card_scheme": paymentData.paymentMethodData.info.cardNetwork,
"redirect_url": "https://example.com/callback"
}
}"
We strongly recommend always providing a redirect_url
, just in case any connection
is configured to use 3-D Secure.
This URL will be appended with both a transaction ID
and status (e.g. https://example.com/callback?transaction_id=123 &transaction_status=capture_succeeded
) after 3-D Secure has been completed.
Test Google Pay
Please follow the Google Pay documentation with further guides on how to add test cards for use in a sandbox environment.
