# Accept WS-Federation Request

> Accept a WS-Federation request to initiate a login flow.

## Endpoint

`GET /wsfed/{clientId}`

This endpoint accepts a WS-Federation request to initiate a login.

### Remarks

* The `wtrealm` parameter must be in one of these formats:
  * `urn:clientID` (for example, `urn:${account.clientId}`)
  * If this parameter does not begin with a urn, the `client.clientAliases` array is used for look-up. This can only be set with the [/api/v2/clients](https://auth0.com/docs/api/management/v2/clients/get-clients) Management API.
* The `whr` parameter is mapped to the connection like this: `urn:CONNECTION_NAME`. For example, `urn:google-oauth2` indicates login with Google. If there is no `whr` parameter included, the user will be directed to the [Auth0 Login Page](https://auth0.com/docs/login_page).
