Okta event hook lambda example

gistfile1.txt

const okta = require('@okta/okta-sdk-nodejs');

const client = new okta.Client({
    orgUrl: 'https://dev-xxxxx.oktapreview.com/',
    token: 'xxxxxx'
});

exports.handler = async (event) => {
    if (event.requestContext.http.method === 'POST') {
        console.log('data event with body: ', event.body);
        const oktaEvents = JSON.parse(event.body).data.events;

        const targetUserId = oktaEvents[0].target[0].id;

        console.log('getting user ', targetUserId);
        const user = await client.getUser(targetUserId);
        console.log('got user ', targetUserId);

        user.profile.costCenter = 'Data from lambda';

        console.log('updating user ', user.profile.login);
        await user.update();
        console.log('user ', user.profile.login, ' updated');

        return {
                statusCode: 200,
                body: {'message' : 'OK'},
            };

    } else {
        console.log('verification request, header value is: ' + event.headers['x-okta-verification-challenge']);
        return {
            "verification" : event.headers["x-okta-verification-challenge"]
        };
    }
};

For a simplicity only first event is taken care of
