Integration Overview

Network International provides two primary payment integration models designed for different business needs, onboarding requirements, and levels of control.

Before you begin, choose the model that best fits your business:

  • Aggregation (PayFast) — Fast, all-in-one solution without a separate merchant account

  • Gateway (PayGate) — Flexible gateway for businesses with their own acquiring relationship

Selecting the correct model ensures a smoother onboarding experience and avoids unnecessary rework later.


Aggregation Integration (PayFast)

Aggregation is an all-in-one payment solution where merchants transact under PayFast’s acquiring relationships. This allows businesses to accept payments quickly without setting up their own merchant account with a bank.

It is ideal for businesses that want a fast, simplified route to accepting payments online.

Best suited for

  • Startups and small to medium-sized businesses

  • Merchants who do not have an existing acquiring relationship

  • Businesses that want rapid onboarding and minimal setup

  • Platforms prioritising speed over deep customisation

Key characteristics

  • Fast onboarding and activation

  • Simplified configuration via dashboard credentials

Gateway Integration (PayGate)

Gateway integration connects your business directly to your own acquiring bank while PayGate provides the secure payment processing layer.

This model offers greater control, configurability, and scalability for businesses with complex requirements.

Best suited for

  • Medium to large enterprises

  • Businesses with an existing merchant account

  • Organisations requiring customised payment flows

  • Merchants processing high transaction volumes

  • Businesses with specific compliance or reporting needs
