New in Hire | update calendar slots via API

Update interview slots without disrupting scheduled candidates.

You can now update calendar slot details, including capacity, timing, and assignment, without needing to delete and recreate the slot.

For teams using integrations or automation with Fountain, this makes it easier to manage scheduling changes without impacting candidates.

What’s new

• New API endpoint: PATCH /v2/available_slots/{id}

• Update slot capacity without canceling or affecting existing bookings

• Modify key fields including time, location, instructions, assigned recruiter, and stage associations

• Supports partial updates so only the fields you include will be changed

Why it matters

This removes the need to delete and recreate calendar slots to make updates, reducing the risk of disrupting scheduled candidates and making it easier to manage interview availability programmatically.

What to expect

• Existing bookings are not impacted when updating a slot

• Validation prevents reducing capacity below the number of confirmed bookings

• No changes to your current workflows unless you choose to use this endpoint
