Custom API Development & Integration – Melbourne & Sydney

API Integration Specialists in Australia

Our developers have experience with countless APIs, providing there is documentation, a clear desired outcome and access to API accounts – the sky is the limit when it comes to our API Integration capabilities.

3rd Party API Integration

If your company is looking to speed up manual processes or time consuming activities and your partner has an API access point then it is the perfect way to automate your business and potentially save hours per week.

Custom APIs we work with include:

  • Stripe and PayPal API (and other payment gateways)
  • Shopify and WooCommerce API (e-commerce)
  • Google and Facebook Single Sign-on (SSO) Authentication APIs
  • Zoom API (for Video-Conferencing, Virtual Event Portals)
  • Any REST API
  • Any Web-Based API
  • ActionHRM API
  • Bridge LMS API
  • Hubspot API

Custom API Development for Businesses

Perhaps you don’t have an API for your own internal systems and are looking to create endpoints for your clients to interact with your systems.

In that case, building a custom API for your own business may be the right option. This will allow your operations to scale faster as well as reduce the need for manual input in every step of the process.

Custom API Development for Courier, Deliveries and Shipping

Modern E-commerce platforms are robust solutions for selling products online, however the fulfilment and logistics aspect can be challenging to integrate as there are different data formats and a large range of integration points.

The benefits of automation in this space are apparent when dealing with large order quantities and any optimisation which your business can achieve in this area will have compounding benefits as you scale.

Some of the platforms which we have integrated with include:

  • Be Cool Couriers API (courier and dispatch automation)
  • Australia Post and TNT APIs
  • Sendle API
  • Various Third-Party Logistics APIs (3PL) or Fulfilment Centre APIs.
We usually integrate this with the major e-commerce platforms, either through a custom app, plugin or extended functionality.

Simplex Software has been integrating and building custom APIs since 2012 and is well equipped to help your business.

Our clients are based throughout Sydney, Melbourne, Brisbane, Perth and other metropolitan CBDs of Australia.

Great working with Simplex Software on this project. Best thing about this job was the attention to detailing, the proactive nature of finding things our team missed and sorting it out whilst communicating along the way. Already scheduled them in on the next project.
