Does Halaxy Have an API? Yes, and Here Is What You Can Do With It

This question comes up constantly and there is surprisingly little written about it, so here is a plain answer for practice managers rather than developers.

Does Halaxy have a public API?

Yes. Halaxy publishes developer documentation at developers.halaxy.com, with an API reference, guides and worked recipes for common use cases. It is a genuine public API, not a private arrangement you have to negotiate your way into.

It is built on FHIR, which stands for Fast Healthcare Interoperability Resources and is the international standard for exchanging health information. FHIR has been adopted by health systems and governments worldwide, and building on it means a developer who has worked with health data before already understands the shape of your data.

What can the API actually do?

The parts that matter most for a busy practice are the appointment endpoints and the webhooks.

• Appointments can be created, read and updated, which is what makes genuine two-way booking possible rather than a one-way export
• Webhooks push changes out to other systems in real time, so an external tool can react the moment something changes rather than waiting for a nightly sync
• The API Key Manager lets you generate keys scoped to specific data, and revoke any key whenever you want

That last point deserves more attention than it usually gets. Scoped, revocable keys mean access to your practice runs through a control you hold. You can grant a booking tool exactly what it needs to book, and nothing else.

What does it cost?

The API is a paid Halaxy subscription, currently 150 credits per month with a 30 day free trial. It is billed by Halaxy, so budget for it separately from whatever tool you are connecting. Confirm the current figure with Halaxy directly, since pricing changes.

The free trial is genuinely useful here, because it lets you prove a connection works against your own diary before anyone commits to anything longer term.

How does this compare to other Australian practice software?

This varies far more than the marketing suggests, and it is worth understanding before you choose a system rather than after. Broadly, Australian practice software falls into three groups.

• Systems that publish developer documentation openly, so anyone can build against them. Halaxy sits here, as do Cliniko, coreplus and Nookal. This is the group where direct booking is realistic and quick.
• Systems that run an application-gated partner programme. The path exists and is documented, but you have to be accepted, which takes time. Magentus, which owns MedicalDirector and Gentu, runs a developer partner programme, and Best Practice and Centaur operate similarly.
• Systems where integration happens through a platform or a direct arrangement rather than open docs. Zedmed connects third parties through Halo Connect, an interoperability layer built on SQL and FHIR that you enable from inside Zedmed.

None of these makes for better or worse clinical software. But if automation matters to you, which group your system is in determines how quickly anything can be connected, and almost nobody raises it during a software sales process. We keep a running view of where each system sits on the integrations page.

What should I automate first?

Having an API does not mean you should connect everything at once. The practice system is one part of a clinic's operations, and the highest-return automation is usually the piece that touches patients before they ever reach your diary.

The phone

This is usually the biggest single win. An AI receptionist answers the calls your team cannot get to, and because Halaxy exposes appointment endpoints, the booking goes into your diary rather than arriving as a message somebody has to re-key. Every after-hours enquiry that used to become a voicemail becomes an actual appointment. See AI receptionist for Halaxy for how this works in practice.

Intake and forms

New patient intake is frequently the most repetitive job at the front desk. Capturing it through your own form, routed to the right practitioner, means your team is reviewing information rather than transcribing it over the phone.

Follow-up and recall

Following up enquiries that did not book, and prompting patients who have lapsed, is work that almost never gets done consistently by a busy front desk. It runs perfectly well from your own records without needing to reach into the practice system.

Reporting

Knowing how many calls you missed, when they came in, and what proportion turned into bookings is usually more actionable than any single integration. Most practices have never seen this data, and it tends to change what they prioritise.

What should I ask a vendor who claims they integrate?

This is the practical part, and it applies well beyond us. Three questions will separate real integrations from marketing.

1. 1.Ask them to name the integration path. A real answer sounds like published API documentation, an approved partner programme, or a named marketplace listing. A vague answer about connecting to everything is not an answer.
2. 2.Ask to see a live listing on the vendor's own site, or a working demo against a test account. If they are a certified partner, there is a page proving it.
3. 3.Ask what happens when it cannot write directly. Every honest vendor has a fallback, and the quality of that fallback is what you will actually be living with.

A vendor who tells you plainly where the limits are is describing a system they have actually built. A vendor who says everything integrates is describing a slide.

How should we grant a vendor access?

Use the API Key Manager, and grant the least access that does the job. A booking tool needs to see availability and write appointments. It does not need everything else, and a vendor who cannot explain why they need a given permission probably has not thought about it.

Keep the ability to revoke. The point of a scoped, revocable key is that ending a vendor relationship is a two-minute job rather than a negotiation. Ask, before you sign anything, what happens to data already captured if you switch the key off.

If you want to talk through what is realistic for your practice, book a discovery call. We will tell you which of the three groups your system is in, and we will tell you if we think the automation case is weak.
