Resource Owner Password Grant

Deprecation Notice

There is a more recent version of this OpenId Connect API available. Learn more.

This endpoint will be removed from service on April 20th 2021.

Use this API to authenticate a given user’s username and password. It makes use of the OpenID password grant and upon success will create a session and return an access token.

Note that the access token returned is different to the access token generated via the OAuth 2.0 Tokens API. Therefore it can not be used to authorize API calls against other endpoints such as Users or Events.

Resource URL

Header Parameter

Authorization

required

string

Set to Basic <base64 encoded "clientId:clientSecret">.

The client_id and client_secret are generated when you configure your OpenId Connect app in OneLogin.
