# Update quota
Updates a quota by its ID.
A quota is the number of asset shares. One asset can consist of a single share or multiple shares.
You can get quota IDs with the List asset quotas endpoint.
This endpoint generates a [Quota updated](https://developers.pismo.io/events/docs/assets-quota-update-1) event.
