Integrations
LeaveSync is built exclusively for Xero Payroll. It connects via OAuth, syncs leave data continuously, and writes approved leave submissions back to Xero. Xero remains your payroll source of truth.
LeaveSync supports Xero Payroll in three regions. Each region has its own leave type configuration, and LeaveSync handles each correctly.
AU
Supports Xero Payroll Australia leave types including annual leave, sick leave, long service leave, personal carer's leave, and public holidays.
NZ
Supports Xero Payroll New Zealand leave types including annual leave, sick leave, alternative leave, bereavement leave, and statutory holidays.
UK
Supports Xero Payroll United Kingdom leave types including annual leave, sick leave, maternity and paternity leave, and statutory leave entitlements.
LeaveSync accesses only payroll data relevant to leave and availability. It does not read salary, banking, tax, or superannuation data.
Reads from Xero
Writes to Xero
The Xero OAuth flow is standard and takes a few minutes. You authorise LeaveSync directly from your Xero account, no third-party credentials required.
In LeaveSync, navigate to Settings and select Connect Xero. You will be redirected to Xero to authorise access.
Log in to Xero if prompted, select the payroll file you want to connect, and approve the permission request. LeaveSync requests read and write access to payroll data only.
If your Xero account contains multiple payroll files, select the one to associate with this LeaveSync organisation. One payroll file per organisation.
LeaveSync immediately syncs employees and leave data. Depending on the size of your payroll file, the first sync takes between 30 seconds and a few minutes.
LeaveSync runs scheduled syncs to keep availability data current. Here is how data flows between systems.
Xero employee records are synced into LeaveSync. When a new employee is added in Xero, they appear in LeaveSync after the next sync. Terminated employees are archived automatically.
Approved leave from Xero is continuously synced. Leave data is normalised into a canonical availability model. The raw Xero payload is retained for audit purposes.
When a manager approves or declines a leave request in LeaveSync, the decision is written back to Xero synchronously. There is no batch process or delay.
Xero OAuth tokens are encrypted at rest using industry-standard encryption. Tokens are never exposed to client-side code or stored in plaintext. LeaveSync rotates tokens proactively before expiry. If you revoke access in Xero, the connection is deactivated immediately on the next sync attempt.
