# Delete audience API

> Delete an audience and its membership, freeing a slot against your plan's audience limit. Free.

## Frequently asked questions

<AccordionGroup>
  <Accordion title="Do I get the credit back for a computed audience?">
    No. The build already ran and was charged on completion; deleting does not refund it.
  </Accordion>

  <Accordion title="What happens to alerts scoped to this audience?">
    An alert with a `segment_id` scope resolves membership at each sweep, so deleting the audience will break that alert. Delete or re-scope the alert first.
