API integration services in Australia

Start by checking for a ready-made connector. Products often have official integrations for common tasks, which can cover your needs without a custom build. Where the flow is simple and the volume is low, a platform such as Zapier or Make gives your staff a way to adjust it themselves. Custom code fits higher volumes, more complex logic and stricter error handling, with more work involved in building the flow.

Timing is a separate choice. A webhook pushes changes as they happen, but it needs an endpoint that can receive them and logic to handle duplicate events. A scheduled batch is simpler and suits reports or overnight updates. You do not have to make every flow real-time: choose the timing that fits how your team uses the data.

A missing API does not always end the discussion. We can often work with exports or email when a system has no API, although that changes how information reaches the next system. We learn your business and goals, then agree the scope with you so the chosen approach fits the work you need it to do.

Australia uses the Peppol framework for e-invoicing. If you use it, we connect your accounting systems and agree what invoice information needs to pass through your e-invoicing workflow. That gives the invoice flow a defined place in the integration, alongside the other accounting connections you need.

Surcharging on debit, prepaid and credit card payments on the eftpos, Mastercard and Visa networks was removed from 1 October 2026. When we integrate your payment gateway, we set up the checkout without those surcharges. We also discuss which gateway you use, including Stripe, Razorpay, PayPal or a local gateway.

Bring these details to the first discussion. They give us a useful picture of the systems, people and records involved.

• A list of the systems and their plans or editions, including whether API access is included.
• Sample records, including the awkward cases your team currently handles by hand.
• The owner of each system and the vendor support contacts who can answer access and permission questions.
• The person who should receive a failed-sync alert, and how quickly they need to act.
• Your current arrangements for API keys or OAuth tokensstorage, renewal and ownership beyond a single employee.

  Leaving ownership unclear

  In a two-way sync, an older record can overwrite a good one. Decide which system owns each piece of data before records start moving.

• !

  Testing only ideal records

  Include blanks, odd characters, duplicates and cancelled orders in tests, so you can find mappings that fail on real data.

• !

  Assuming events arrive once and in order

  Record processed event IDs and avoid depending on delivery order when handling webhooks.

• !

  Leaving failures unnoticed

  Add an alert for failed syncs so missing orders or invoices do not sit unnoticed while your team continues working.
