# Update a tag

`PATCH https://api.cademi.com.br/api/v3/tags/{tag_id}`

Operation ID: `tags.update` · API v3

Renames a tag. The new name must be unique within the account.

To avoid overwriting a newer version, send the `ETag` returned by the retrieve operation in the `If-Match` header. If the header is omitted, the update is applied to the current revision.

Replicated tags are read-only. Attempts to update them return `403 Forbidden` with the `replica_readonly` error code.

Required permissions: `tags.update`.
