Getting provider's access token

You can get the Third Party Provider's access token to query their APIs with the following method:

NodeJS

import SuperTokens from "supertokens-node";
import ThirdPartyPasswordless from "supertokens-node/recipe/thirdpartypasswordless";
import Session from "supertokens-node/recipe/session";

SuperTokens.init({
    appInfo: {
        apiDomain: "...",
        appName: "...",
        websiteDomain: "..."
    },
    supertokens: {
        connectionURI: "...",
    },
    recipeList: [
        ThirdPartyPasswordless.init({
            override: {
                apis: (originalImplementation) => {
                    return {
                        ...originalImplementation,

                        // we override the thirdparty sign in / up API
                        thirdPartySignInUpPOST: async function (input) {
                            if (originalImplementation.thirdPartySignInUpPOST === undefined) {
                                throw Error("Should never come here");
                            }

                            let response = await originalImplementation.thirdPartySignInUpPOST(input);

                            // if sign in / up was successful...
                            if (response.status === "OK") {
                                // In this example we are using Google as our provider
                                let accessToken = response.authCodeResponse.access_token

                                // TODO: ...
                            }

                            return response;
                        },
                    }
                }
            },
        }),
        Session.init()
    ]
});
