## ConvertKit integration

ConvertKit (now rebranded as Kit) is an email marketing platform designed for creators, bloggers, and online businesses. It provides tools for managing subscribers, creating email sequences, building landing pages, and sending broadcast emails. Integrating ConvertKit with Frontegg allows your application to manage subscribers, tags, forms, sequences, and broadcasts on behalf of your users through API key authentication.

Prerequisites
- A ConvertKit (Kit) account (free or paid plan). Sign up at [kit.com](https://kit.com)


### Connect ConvertKit

#### Step 1: Open the settings menu

Log in to your [Kit account](https://app.kit.com) and click your **profile avatar** in the top-right corner. Select **Settings** from the dropdown menu.

#### Step 2: Navigate to developer settings

In the Settings sidebar on the left, click **Developer** under the Settings section. This opens the Developer page where you can find your API credentials.

#### Step 3: Copy your API key and API secret

On the Developer page, scroll down to the **V3 Key** section. You will see two fields:

- **Your API Key** — used for public API endpoints (listing forms, sequences, tags).
- **API Secret** — used for sensitive API endpoints (managing subscribers, broadcasts, account info). Click **Show** to reveal its value.


Click the **Copy** button next to each field and store both values securely.

Keep your credentials secure
Your API Secret grants access to sensitive subscriber data. Never share it publicly or commit it to version control.

1. Open the **Frontegg portal** and navigate to **[Environment]** → **Integrations** → **ConvertKit**.
2. Enter the **API Key** and **API Secret** in the corresponding fields.
