Kit Setup Guide
Connect your Kit account using OAuth authentication via the app store
Overview
How Kit Integration Works
Kit uses OAuth 2.0 authentication through their app marketplace. You'll install our "AdKiit" app from the Kit app store, which gives us secure access to your account without sharing any passwords or API keys. Once you have connected your Kit account, you will be able to add unlimited publications. When you add a publication, AdKiit will automatically create setup a webhook to track server side conversions.
What's the difference between GTM and Webhook Events?
AdKiit captures subscription events in two ways:
GTM Script (Client-Side):Runs in the subscriber's browser via Google Tag Manager, firing as soon as someone signs up. Because it relies on the browser, these events can sometimes be blocked by ad blockers or privacy settings.
Webhooks (Server-Side): Created automatically when you add a new newsletter. They send subscription events directly from your email platform to AdKiit, ensuring events are captured even if the client-side script was blocked.
Using both together ensures subscriptions are tracked as quickly as possible (via GTM) and as reliably as possible (via webhooks).
