1. Introduction

Octo3’s e-Commerce Payment Service provides an efficient, secure and easy-to-use payment integration solution to enable merchant systems with online payment capabilities. The document aims at providing merchants necessary information to jump-start the integration process, by interacting with the platform using the pre-defined codes and account information.

To understand extensively how the platform functions, please refer to the following documents.

  • e-Commerce Payment API Specification Document  

  • Asynchronous Notification Merchant Implementation Guide

  • Merchant Portal Guide

2. Submit Your First Transaction / Digital Order (DO)

The e-Commerce Payment Service API is a simple-to-use and secure payment service interface which allows the merchant to integrate real-time payment capability into its system. To immediately submit your first transaction (SALE_ONLY transaction), you can make use of a HTML form and submit a HTTPS POST request. You can quickly create one by copying the following code to a new text document:

 

Assign a unique ID to the transaction by replacing “this_is_the_1st_transaction” with a string in the merch_order_id field.

Revise the parameter values based on the MID account document if necessary. Click “Process payment” to proceed.

3. Complete the transaction

Upon submitting the correct parameters to the platform, you will be redirected to the payment page hosted by the service channel.

If you are using a different MID for making a transaction, please refer to the respective payment flow document and input the payment information as provided in the MID Account Document.
