# Webhooks

> We support the following webhook events

* `negative_balance`: called whenever there is an event for a user that results in a negative balance

* `balance_change`: called anytime a user's balance changes

* `auto_refill`: called whenever a refill is triggered automatically (monthly plan renewal for example)

* `threshold`: called whenever a customizable threshold is hit for a given account

## Create webhooks

Within the settings tab of Fermata control, select Webhooks + Flagbacks from the left hand rail.
