In order to add external OAuth 2.0 Provider integration, you have to create a resource called IdentityProvider. It will be used by auth module to generate redirect links and make API calls to provider to retrieve access token, user data, etc. All examples in this tutorial are executable in Aidbox REST Console.
POST /IdentityProvider​resourceType: IdentityProvidersystem: https://google.comactive: trueid: <provider-id>authorize_endpoint: https://accounts.google.com/o/oauth2/v2/authtoken_endpoint: https://www.googleapis.com/oauth2/v4/tokenuserinfo_endpoint: https://www.googleapis.com/oauth2/v1/userinfoscopes:- https://www.googleapis.com/auth/userinfo.profile- https://www.googleapis.com/auth/userinfo.emailclient:id: <your auth client id>secret: <your auth client secret>
attribute | description |
system | adds identifier for the created user with this system |
authorize_endpoint | OAuth Provider authorization endpoint |
token_endpoint | OAuth Provider access token endpoint |
userinfo_endpoint | OAuth Provider user profile endpoint |
userinfo_header | Some providers require different prefix then "Bearer" for Authorization header in user info request. Fox example, if set to "OAuth" results in: GET /<userinfo_endpoint> with Authorization: Oauth <access token> |
scopes | array of scopes for which you request access from user |
client.id | id of the client you registered in OAuth Provider API |
client.secret | secret of the client you registered in OAuth Provider API |
Next, we have to create Client resource which will receive access token from Aidbox backend later on and use Aidbox API on behalf of the user. We enable authorization_code flow for the application and provide redirect_uri.
POST /Client​id: my-clientgrant_types: ["authorization_code"]first_party: trueauth:authorization_code:redirect_uri: <your app redirect uri>
You will also need to register /auth/callback/<provider-id> as callback URI in your OAuth provider client application configuration.
To initiate authorization, redirect user to the endpoint /auth/redirect/<provider-id>. You should provide at least two query parameters client_id and response_type. The following API interactions happen as a result:
GET /auth/redirect/google?client_id=my-client&response_type=code# your application entrypoint# redirects to​GET https://accounts.google.com/o/oauth2/v2/auth?...# user enters his credentials, allows aidbox access to his profile data# provider redirects to​GET /auth/callback/google?...# aidbox receives temporary token, exchanges it on access token by calling​GET https://www.googleapis.com/oauth2/v4/token?...​# using access token, aidbox calls user data endpointGET https://www.googleapis.com/oauth2/v1/userinfo# then it creates User resource and continues with the flow specified# in response_type query param​GET <your app redirect uri>?code=...​
By default, everything that is returned by provider's userinfo endpoint gets stored into User.data. You can also configure mapping to other User attributes by adding 'toScim' object into IdentityProvider.
PUT /IdentityProvider/<provider-id>​toScim:default_email:first_name:- name- givenNamelast_name:- name- givenName
Each key here refers to the key in the userinfo response object, while value is an array that specifies path in User resource.
