Adding a custom third party provider

Whilst there are several built-in providers that SuperTokens offers, you may want to add your own provider. This page will show you how to do that on a per tenant basis so that you can add a custom enterprise connection or a social connection to each tenant.

Once you have created a tenant, you want to call the API / function to create a new provider for the tenant as shown below:

Via OAuth endpoints#

import Multiteancy from "supertokens-node/recipe/multitenancy";

async function createTenant() {
    let resp = await Multiteancy.createOrUpdateThirdPartyConfig("customer1", {
        thirdPartyId: "custom",
        name: "Custom Provider",
        clients: [{
            clientId: "...",
            clientSecret: "...",
            scope: ["email", "profile"]
        }],
        authorizationEndpoint: "https://example.com/oauth/authorize",
        authorizationEndpointQueryParams: { // optional
            "someKey1": "value1",
            "someKey2": null,
        },
        tokenEndpoint: "https://example.com/oauth/token",
        tokenEndpointBodyParams: {
            "someKey1": "value1",
        },
        userInfoEndpoint: "https://example.com/oauth/userinfo",
        userInfoMap: {
            fromUserInfoAPI: {
                userId: "id",
                email: "email",
                emailVerified: "email_verified",
            }
        }
    });

    if (resp.createdNew) {
        // custom provider added to tenant
    } else {
        // existing custom provider config overwritten for tenant
    }
}

  • You can see all the options here.

  • The tenantId is a unique ID that identifies the tenant for whom you want to add the custom provider. If not specified, it will add it for the "public" tenantId (which is the default one).

  • The thirdPartyId is a unique ID for this provider which helps SuperTokens identify the provider. For example, the thirdPartyId for the built in Google provider is "google".

  • The name field is sent to the frontend and can be used to render the login button on the frontend UI. For example, if you set the name to "XYZ", the pre built UI on the frontend will display the text "Login using XYZ" on the button for this provider.

  • The clients array represents the client credentials / settings for each of your frontend clients. Most of the time, one client item is enough, but if the provider requires to use different client ID / secret for web vs mobile apps, you would need to add two items to this array - one for web, and one for mobile. In this case, you would also need to add the clientType: string config for each of the items in the clients array.

  • AuthorizationEndpoint corresponds to the URL to which the user should be redirected to for the login. For example for Google, this is "https://accounts.google.com/o/oauth2/v2/auth".

    • AuthorizationEndpointQueryParams is an optional config, but it can be used to modify the query params added to the AuthorizationEndpoint. You can use this config to add new keys, or to modify or remove (by setting to null) query params added by SuperTokens.

  • TokenEndpoint corresponds to the API that is used to exchange Authorization Code for the user's Access Token or the ID Token. For example for Google, the value of this is "https://oauth2.googleapis.com/token".

    • TokenEndpointBodyParams is an optional config, but it can be used to modify the request body sent to the TokenEndpoint. You can use this config to add new keys, or to modify or remove (by setting to null) body params added by SuperTokens.

  • UserInfoEndpoint corresponds to the API that provides user information using the AccessToken. For Google, the value of this is "https://www.googleapis.com/oauth2/v1/userinfo". Once this endpoint is called, SuperTokens fetches user info (like their userID and email ID) from the JSON response based on the config for UserInfoMap.FromUserInfoAPI map. For example, the value of the map for Google is:

    {
        userId: "id",
        email: "email",
        emailVerified: "email_verified"
    }

    This means that when SuperTokens gets back the JSON from the /userinfo endpoint, it will read the jsonResponse.id field to get the user's Google ID, the jsonResponse.email field to get back the user's email and the jsonResponse.email_verified field to know if the user's email is verified or not.

    If you want to fetch a value from a nested JSON object, you can specify something like userId: "user.id", in which case the provider's user ID will be fetched using jsonResponse.user.id.

Via Open ID connect (OIDC) endpoints#

If the provider is Open ID Connect (OIDC) compatible, you can provide url for the OIDCDiscoverEndpoint config. The backend SDK will automatically discover authorization endpoint, token endpoint and the user info endpoint by querying the <OIDCDiscoverEndpoint>/.well-known/openid-configuration.

Below is an example of how to set the OIDC discovery endpoint:

import Multiteancy from "supertokens-node/recipe/multitenancy";

async function createTenant() {
    let resp = await Multiteancy.createOrUpdateThirdPartyConfig("customer1", {
        thirdPartyId: "custom",
        name: "Custom Provider",
        clients: [{
            clientId: "...",
            clientSecret: "...",
            scope: ["email", "profile"]
        }],
        oidcDiscoveryEndpoint: "https://example.com/.well-known/openid-configuration",
        authorizationEndpointQueryParams: { // optional
            "someKey1": "value1",
            "someKey2": null,
        },
        userInfoMap: {
            fromIdTokenPayload: {
                userId: "id",
                email: "email",
                emailVerified: "email_verified",
            }
        }
    });

    if (resp.createdNew) {
        // custom provider added to tenant
    } else {
        // existing custom provider config overwritten for tenant
    }
}

  • You can see all the options here.

  • The tenantId is a unique ID that identifies the tenant for whom you want to add the custom provider. If not specified, it will add it for the "public" tenantId (which is the default one).

  • The config values are similar to the ones in the "Via OAuth endpoints" method. Please read that section to understand the thirdPartyId, name, clients config.
  • Unlike the "Via OAuth endpoints", we extract the user's info from the ID token payload using the config specified by you in the UserInfoMap.FromIdTokenPayload map.
  • You can also add the UserInfoMap.FromUserInfoAPI map as done in the "Via OAuth endpoints" section. SuperTokens will auto merge the user information.
