WHAT ARE YOU BUILDING?
Your product.
A head start on payroll.
Give your customers a payroll experience that fits their work. Start with the parts Kua provides, then build what makes your product different.
Add payroll to your HR platform
Help customers move from employee details into payroll without entering the same information twice.
Connect an existing tool
Keep leave requests, goals and payroll updates connected to the tools a team already uses.
WHEN SOMETHING CHANGES
Your other tools can know, too.
Receive signed events from Kua, verify the delivery and update your own system. Keep the original event ID so a retry does not become a second action.
Build a webhook receiver01
KUA EVENT

FROM IDEA TO FIRST REQUEST
Start with one useful connection.
Read before you write.
Use the quickstart to read your company’s payroll runs, then build from that first request.

Try employee creation and payroll drafts in Test mode. Leave, performance and webhooks use Live keys. Add salary details in Kua before creating a payroll draft. The public API does not send payments or manage wallets.
