# Update registration settings

`PATCH https://api.cademi.com.br/api/v3/settings/registration`

Operation ID: `settings.registration.update` · API v3

Updates the registration settings. Only the fields included in the request are changed: setting a field to `null` clears its configured value and restores the default, and omitted fields are left unchanged.

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

Required permissions: `settings.update_registration`.

## Parameters

| Name | In | Type | Required | Description |
