Instructions detailing how to integrate Google Pay™ into your Website using NoahPay as your gateway

Pre-requisites

  • Read the Google Pay Web Brand Guidelines
  • Follow Google Pay's [Deploy production environment guidelines](Follow Google Pay's Deploy production environment guidelines). In this step you will obtain a merchantID. By integrating Google Pay, you agree to Google's terms of service.
  • Contact the NoahPay support team to have Google Pay enabled on your account. You will be supplied a gatewayMerchantID.

Implementation Steps

Follow the instructions in the following Google guides to implement a Google Pay button in your app:

Google Pay Web developer documentation
Google Pay Web integration checklist

When setting up the tokenizationSpecification object, specify the following values for the gateway and gatewayMerchantId values:

const tokenizationSpecification = {
  type: 'PAYMENT_GATEWAY',
  parameters: {
    'gateway': 'noahpay',
    'gatewayMerchantId': '<provided by NoahPay>'
  }
};

The Google Pay button will generate an encrypted token that you must then include in a request to the NoahPay API to:

  • Create a purchase using the card in the Google Pay payload
  • Or tokenize the card details in the Google Pay payload

The following documentation outlines the format of the two API calls:

  • Create a purchase using a wallet
  • Tokenize a card with wallet credentials
