Logs a user in. In this example, we call your lookup URL (let’s say, https://oauth.provider/user?t=<%= accessToken %>) with the access token (1234). The lookup URL returns { id: 'abcd' } in this case. We will match this id with the OAuthIdentity stored in the user information in our db. If everything checks out, the user is logged in and redirected to the home page.
accessTokenstringOptional Will be passed through your lookup URL to get the user ID. Required if no code.
Will be passed to the OAuth token endpoint to get a token. Required if no accessToken.
Override where the user will navigate to after successfully logging in. errorRedirectstringOptional If an error happens, redirects the user to this url, with at least query parameters code, errorName and message.
