How to Get Your Employment Hero API Key (and What to Build With It)

How Employment Hero API access works

Employment Hero uses OAuth 2.0 credentials issued through the Employment Hero developer programme. The exact screens move around as Employment Hero updates its interface, so rather than repeat a menu path that may already be out of date, the reliable source is the official documentation: Employment Hero developer documentation.

Employment Hero covers HR and payroll as related but distinct areas, and API availability differs between them. Confirm which modules your plan exposes before scoping.

What the Employment Hero API lets you do

The Employment Hero API gives you programmatic access to the core data in your account. Broadly that covers:

• Employees, onboarding and contracts
• Leave requests and balances
• Timesheets and rostering data
• Pay runs and payroll categories
• Certifications and compliance records
• Organisation structure and teams

With that access you can push data into accounting or reporting systems, keep records in step across tools, and build dashboards from live Employment Hero data rather than from exports someone has to remember to run.

Employment Hero and no-code tools

Zapier support for Employment Hero is limited. Zapier coverage is limited, so most integrations use the API or the supported native connections. That is why searches for connecting Employment Hero through no-code tools tend to turn up workarounds rather than a clean answer.

Building with the Employment Hero API

Connecting Employment Hero to another system means working through five things, in roughly this order:

1. Authenticate using the credentials above, and store them somewhere your team can rotate
2. Map the data, deciding what moves between Employment Hero and the other system, in which direction, and triggered by what
3. Handle the edge cases, such as a record that already exists on one side but not the other, or a partially completed transaction
4. Build error handling, so a failed call is retried or surfaced rather than silently dropped
5. Set up monitoring, so you find out something stopped working before it becomes an accounting problem

A common pairing is Employment Hero with Xero or MYOB. Read-only reporting is usually straightforward. Live two-way sync is where the mapping and error handling turn it into a proper development project.

When to bring in a developer

Some Employment Hero API work is genuinely straightforward. Some is not. An honest split:

These integrations look simple from the outside. The work is in the detail: field mapping, conflict resolution, error recovery, and keeping everything in step as both Employment Hero and the connected system change over time.

If the integration touches invoicing, stock or payroll, getting it wrong has real financial consequences. A properly built integration with monitoring and alerting is worth the upfront cost.
