# Create a schedule override

POST https://api.slotflow.dev/v1/humans/{humanId}/overrides
Content-Type: application/json

Create a schedule override for a human. Overrides modify availability beyond the base schedule.

**Block overrides** remove availability:
- All-day blocks for vacations or holidays
- Time-specific blocks for recurring meetings or focus time

**Open overrides** add extra availability:
- Weekend or evening hours for overtime
- Special event availability outside normal schedule

Overrides support date ranges (`start_date` to `end_date`) and recurring patterns via the `recurrence` field.
