Setup
Gist can be initialized anywhere within your app.
The organizationId property can be retrieved from the Gist dashboard.
When useGuestSession is set to true, the guest user will be able to receive broadcasts. This setting defaults to false.
Logging is optional.
1
Gist.setup({ organizationId: "your-organization-id", useGuestSession: false, logging: true });

User Token
If your app is relying on Gist’s webhook service to trigger in-app messages, a user token must be set. This user token should be generated by your services and set at any point during runtime, for example, login or registration.
1
Gist.setUserToken("unique-user-token");
Copied!
An optional expiry date parameter can be sent.
To clear the user token:
1
Gist.clearUserToken()

Current Route
Since messages can be targeted to show on specific pages, Gist uses window.location to figure out where the user is at, this can be overridden by calling the setCurrentRoute.
1
Gist.setCurrentRoute("users/home");
