Finding the Kit API Key
The API Key is an authentication code used to identify and verify an account or a user when you want to connect it with another tool.
Therefore, the first thing you’ll need to connect your Kit account to the Thrive Dashboard is the API Key.
To begin, first log in to your Kit account.
Once logged in to your Kit account dashboard, click on the profile on the right and click on Settings.
On the Settings page, in the left column, under Settings, click on Developer.
On the Developer page, you’ll see two API keys that you can use.
As of October 2025 (when this document is updated), the API V4 is in its beta version and therefore, copy the API V3 key to proceed with the integration with Thrive Themes.
Adding the Kit API Key to the Thrive Dashboard
To proceed with the API connection between Kit and the Thrive Dashboard, it is important to enter the Kit API Key in Thrive Themes.
To begin, open your WordPress admin area, navigate to Thrive Dashboard >> Thrive Dashboard, scroll down to API Connections, and click on Manage Connections.
Clicking on Manage Connections will take you to the Active Connections page. On this page, scroll to the Add New Connection block and click on it.
When you click to add a new connection, you’ll see a dropdown where you can select the app, ConvertKit/Seva, that you want to connect to.
Selecting ConvertKit will ask you to enter the API Key. To proceed, enter the API Key, and click Connect.
After clicking Connect, you’ll see a success message saying that Kit is now connected.
Connecting Kit to a Lead Generation Element
After you’ve established a connection between Kit and the Thrive Dashboard, you can proceed to add the connection to a Lead Generation element you’ve used or plan to use.
Before we build a connection, please make sure you’ve added the Lead Generation element on a page or post using Thrive Architect. You can read our document to know more about the Lead Generation element.
Once you are ready with a post or page with the Lead Generation element on it, click on the element to see its options open in the left sidebar.
In the Lead Generation options seen in the left sidebar, open Main Options and click on the Add Connection button. This will help you determine the application to which you’d like to send the leads.
After clicking on Add Connection, you’ll see a dropdown where you select the connection you want to add. In this dropdown, select ConvertKit/Seva.
After selecting ConvertKit/Seva, select the list you want to add the leads to and the tags you want to add to them, and click the Apply button.
Connecting Kit to Thrive Leads
To be able to connect Kit with Thrive Leads, you need to make sure you have a form created using Thrive Leads.
You can refer to our detailed documentation on how to create a form using Thrive Leads.
To be able to connect Kit with a Thrive Leads form, begin by opening your WordPress admin area, navigating to Thrive Dashboard >> Thrive Leads, and click on a Lead Group that contains the form you want to edit.
When you click on a Lead Group, it’ll display the form types created under it. To connect a specific form type, click on the “Pen” or Edit icon seen on the right side of the form name.
When you choose to edit the form type, it’ll take you to a page where you’ll see the form/forms created under this form type.
On this page, click on the pen or edit icon seen on the right side of the form name.
When you click to edit the form, it’ll take you to the editor where you can modify the form elements.
In the editor, click on the form and see its options in the left sidebar.
In the left sidebar, open Main Options, and click on the Add Connection button so you can send your leads to a list you select.
Clicking on Add Connection will show a dropdown. Click on this dropdown and select ConvertKit/Seva to establish the connection.
After selecting ConvertKit/Seva, select the list you want to add the leads to and the tags you want to add to them, and click the Apply button.
We’ve just seen how you can establish an API connection between Kit (formerly known as ConvertKit) and Thrive Themes. You can take a look at the video below.
Next, if you want to add custom integrations in Thrive Architect, you can use the Webhook feature to do so.
