Device authorization endpoint
The device authorization endpoint allows a user to grant authorization to a device client using a browser on a second device, such as a smart phone or a computer.
The OAuth 2.0 Device Authorization Grant defines the device authorization endpoint. Based on the specification, the device sends a device authorization request to PingFederate, the authorization server (AS), at its device authorization endpoint.
Per OAuth specifications, this endpoint accepts only the HTTP POST method. |
Endpoint: /as/device_authz.oauth2
The required Content-Type
value is application/x-www-form-urlencoded
. The following table describes parameters for this endpoint.
Parameter | Description |
---|---|
|
A unique identifier the client provides to the resource server to identify itself. This identifier is included with every request the client makes |
(Optional) |
The scope of the access request expressed as a list of space-delimited, case-sensitive strings. Scopes can also be constrained on a client-to-client basis. For more information about scopes, see Scopes and scope management. |
Both the request and the response follow the OAuth 2.0 Device Authorization Grant.
