Create an API key
In the dashboard, go to
Settings → API keys and issue a key. The secret (
kua_live_…) is shown
once — copy it somewhere safe. Prefer a kua_test_… key while you build,
so you work against sandbox data.Make your first request
List your payroll runs. Pass your key in the A successful call returns
X-Api-Key header.200 with a JSON array of runs (empty if you have
none yet).Subscribe to events
Register a webhook so Kua pushes events — like a
completed payroll run — to your systems as they happen.
