## Update Tenant Manager Configuration

This API is used to update the Tenant Manager configuration.

No Id is required to update this object.

This API is used to update an existing Tenant Manager Configuration.

You must specify all of the properties of the Tenant Manager Configuration when calling this API with the `PUT` HTTP method. When used with `PUT`, this API doesn't merge the existing Tenant Manager Configuration and your new data. It replaces the existing Tenant Manager Configuration with your new data.

Utilize the `PATCH` HTTP method to send specific changes to merge into an existing Tenant Manager Configuration.

### Request

[API Key Authentication](https://fusionauth.io/docs/apis/authentication.md#api-key-authentication)

Update the Tenant Manager configuration

`PUT /api/tenant-manager`

`PATCH /api/tenant-manager`

Note

For backward compatibility, the `PATCH` method accepts the same media type (specified by a `Content-Type` of `application/json`) and body as the `PUT` request. You can also use the following media types for different behavior:

*   [JSON Patch/RFC 6902](https://www.rfc-editor.org/rfc/rfc6902): `application/json-patch+json`
*   [JSON Merge Patch/RFC 7396](https://www.rfc-editor.org/rfc/rfc7396): `merge-patch+json`

For details, see the [PATCH documentation](https://fusionauth.io/docs/apis.md#the-patch-http-method).

Using a media type of `application/json` merges the provided request parameters into the existing object. As a result, all parameters are optional with `PATCH`: only provide the values you want to change. To remove a value, provide a `null` value. Patching an `Array` appends all values in the new list to the old list.

#### Request Body

`tenantManagerConfiguration.applicationConfigurations`

*   Array<Object>
*   optional

The list of universal applications enabled for Tenant Manager identity providers.

`tenantManagerConfiguration.applicationConfigurations[x].applicationId`

*   UUID
*   optional

The Id of a universal application enabled for Tenant Manager identity providers.

`tenantManagerConfiguration.attributeFormId`

*   UUID
*   optional

The Id of the registration form used to determine available attribute mapping targets.

`tenantManagerConfiguration.brandName`

*   String
*   optional

The brand name displayed in Tenant Manager.

Example Request JSON

```json
{
  "tenantManagerConfiguration": {
    "applicationConfigurations": [
      {
        "applicationId": "9f5d3df4-2f65-4d2c-b851-6f58fdd7f8fd"

### Update a Tenant Manager Identity Provider Type Configuration

This API is used to update an existing Tenant Manager identity provider type configuration.

You must specify all of the properties of the identity provider type configuration when calling this API with the `PUT` HTTP method. When used with `PUT`, this API doesn't merge the existing type configuration and your new data. It replaces the existing type configuration with your new data.

Utilize the `PATCH` HTTP method to send specific changes to merge into an existing type configuration.

### Request
