# Kit Integration (Formerly Convertkit)

Kit Integration (Formerly Convertkit)

This tutorial will show you how to integrate with [ConvertKit](https://convertkit.com/) using our API integration on OP3:

Please note as of January 7th, 2025, you will need to re-integrate with the new "Kit" integration under "OptimizePress >> Integrations" - You will need to use the new API v4 API key from within your Kit developer settings:

The below guide relates to the older ConvertKit integration that is no longer available. We will update this guide soon to show the steps for the new integration. 

## Part 1: Get ConvertKit API Key and API Secret

After you logon to your ConvertKit account, you'll see a dashboard similar to this:
