## What you can build with the Open API

### Read and write leave data in your own tools

Read and update leaves, users, locations, departments and leave types from your own tools and scripts.

### Create keys with only the access needed

Each key gets only the scopes it needs, with expiry, rotation and revocation, and never more than its owner's role.

### Get signed webhooks for leave events

Signed webhooks tell your system when leave is requested, approved, denied, changed, cancelled or expired.

### Act on behalf of anyone on your team

Send requests as a specific user, so leave booked from your own tools is recorded under the right person.

### Manage automations and reports

Set up automations, notifications and scheduled reports through the API, not just leave requests.
