# Change a service

`PATCH https://evohub.io/api/v1/catalog/components/{ref}`

Part of the [Catalog API](https://docs.evohub.io/catalog.md) reference · operationId `updateComponent`.

Changes only the fields sent. Only `owner_team_id`, `tier`, `tier_id`
and `sla_overrides` may be `null`; send `""` to clear a text field.
A `slug` different from the current one is refused with
`SLUG_IMMUTABLE`.

Requires the `catalog:component:write` scope.
