# Update attribute

> Update mutable fields on an attribute.

Type changes are not allowed — create a new attribute with a different key instead.

<ParamField path="key" type="string" required>
  The attribute key to update.
</ParamField>

<ParamField body="label" type="string">
  Updated label.
</ParamField>

<ParamField body="enum_values" type="array">
  Updated enum values.
</ParamField>

<ParamField body="tags_values" type="array">
  Updated tags values.
</ParamField>

<ParamField body="description" type="string">
  Updated description.
</ParamField>

<ParamField body="is_reviewed" type="boolean">
  Review status.
</ParamField>

<ParamField body="detach" type="boolean">
  When `true`, clears sync metadata (`source_id`, `external_id`, `source_synced_at`) so synced attributes become editable.
</ParamField>

<Warning>
  Synced attributes cannot update label, enum\_values, tags\_values, or description unless `detach` is `true`.
</Warning>
