Google Pay Integration Guide

1. Introduction

Google Pay™ is the fast, simple way that allows you to make card payments without entering card details for each payment. The card data is safely stored by Google. This payment method is available for all devices (mobile phones and computers), regardless of the operating system and web browser.

2. Connection via Portmone.com page

Preconditions

1. You should sign an agreement with Portmone.com.

2. You need to agree with Google Pay Terms of Service.

Description

With this connection method, you do not need to perform additional integrations. The Google Pay button will be displayed on Portmone.com payment page. You can manage payment methods and the order in which the payment instruments (including Google Pay) are displayed using JSON-request (see section 3.2 of documentation) or contacting the cooperation manager.

3. Connection with Google Pay API

Preconditions

1. You should register with Google Pay API.
2. Your website should use HTTPS and support TLS protocol.
3. To integrate your website or mobile application with the Google Pay, proceed according to the following instructions:

• API documentation:

a) for mobile application

b) for website

• Brand guidelines

a) for mobile application

b) for website

How it works?

1. You request the encrypted payment data from your application.
2. Google Pay returns the encrypted data after buyer authentication.
3. You send the encrypted payment data to your server.
4. You send an JSON-request to Portmone.com containing the encrypted data.
5. We send you the payment response
6. You inform the buyer of the outcome

How to integrate the Google Pay method?

Step 1. Use Google Pay API to get PaymentData.

Settings parameters:

a. allowPaymentMethods : CARD

b. tokenizationSpecification = { "type": "PAYMENT_GATEWAY"}

allowedCardNetworks = ['MASTERCARD', 'VISA'];

allowedCardAuthMethods = ['PAN_ONLY', 'CRYPTOGRAM_3DS'];

c. gateway = portmonecom

d. gatewayMerchantId - A unique identifier of the online shop. Assigned to each partner individually when connected to the Portmone.com system.
