  1. Merchant API

Overview

With the integration with EVO Cloud, you can realize all the online payment features that EVO Cloud supports, including Payment, Tokenization, Authentication, the actions you can take after payment, such as Capture, Cancel, Refund and Accept Notification from EVO Cloud, etc.

Before you begin#

Before you start the integration, please:
1.
Confirm with your EVO Cloud account manager that the API integration mode suits your business.
2.
Ask your account manager for the test parameters and scripts.
3.
Read the EVO Cloud API Specification to have a basic concept on the API structure and the basic technical requirements.

Start integrating#

First, build an integration that can make a payment following the introduction in chapter Payment, the primary function that enables you to accept online payment.
Once you build the primary functions, complete the integration by adding more features:
1.
Tokenization: save a user's payment method and make payment later. See chapter Tokenization for more details.
2.
Authentication: authenticate a user before making a payment with a card by 3D Secure or SecurePlus. See chapter Authentication for more details.
3.
Account Status Inquiry (ASI): instead of authenticating the user, authenticate the user's card before making a payment. See chapter Account Status Inquiry (ASI) for more details.
4.
Capture, Cancel, Refund, Customs Clearance, and Accept Notification: the actions you can take after a payment. See chapter After Payment for more details.

Test and go live#

When your integration gets ready, run the test scripts with the parameters provided by your EVO Cloud account manager and submit the test result. You can request your account manager for the EVO Cloud technical support if you get any issues regarding the integration.
Once the EVO Cloud team reviews your test result, your account manager will contact you to go ahead with the required steps to live your integration.
