This guide walks you through connecting Interact with Kit so quiz leads are automatically added as new subscribers in your Kit account. You’ll be able to:

Send quiz leads to Kit in real time
Choose which Kit sequence or form new leads should be added to
Map quiz results and answers to Kit subscriber fields
Use quiz data for segmentation and automation

Before you start

Make sure you have the following:

An active Interact account
An active Kit account
Access to API keys in Kit
At least one created quiz in Interact

💡 Note: This feature is only available in the latest Interact user dashboard at app.tryinteract.com. Log in there to access it.

Step 1. Get your Kit API key

Log in to your Kit account.
Go to your Developer settings.
Under the V3 API key section, copy your API key and your API secret.

⚠️ Keep your API key secure. Anyone with access to this key can add or update subscribers in your Kit account.

Step 2. Connect Kit integration

Log in to Interact.
From your dashboard, go to Quizzes.
Click Edit to open quiz builder.
Go to Lead Generation > Integrations.
Find Kit and click Connect.

6. Paste your Kit API key (v3).

7. Click Connect.

You’ll see a confirmation once the connection is successful.

Step 3. Map quiz results to Kit

When someone completes your quiz, Interact can take different actions in Kit based on the quiz result they receive.

In the integration setup flow, go to the Results step.
You’ll see each quiz result listed separately.

For each quiz result, you can choose what happens in Kit by adding actions. Available actions for Kit include:

Add to Sequence
Add to Form
Update a Subscriber Field
Add a Tag to Subscriber

❗ Important: Each quiz result must be connected to either a Kit Sequence or a Kit Form for the setup to be valid.

Add contacts to a Kit sequence

When someone completes your quiz, Interact can add them to a Kit sequence.

Click Add actions.
Find Add to Sequence.
Select the Kit sequence from the dropdown you want quiz leads added to.

Add contacts to a Kit form

When someone completes your quiz, Interact can add them to a Kit form.

Click Add actions.
Find Add to Form.
Select the Kit form from the dropdown you want quiz leads added to.

Update a subscriber field

You can store the quiz result (or any custom value) directly on the Kit subscriber record.

Click Add actions.
Find Update Subscriber Field.
Select a Kit subscriber field from the dropdown.
Set the value you want saved for this quiz result (the value can be customized).

Add a tag to a subscriber

You can tag subscribers based on the quiz result they receive.

Click Add actions.
Find Add Tag to Subscriber.
Select the tag you want applied when someone receives this quiz result.

Step 4. Map quiz answers to Kit (optional)

In addition to quiz results, you can also send individual quiz answers to Kit and use them for segmentation and automation.

This works the same way as mapping quiz results, but instead of triggering actions based on the final result, actions are triggered based on how someone answers a specific question.

💡 Tip: Quiz answers are great for capturing preferences, intent, or qualifiers (for example: budget, experience level, or goals).

Step 5. Map opt‑in form fields to Kit

Next, connect your Interact opt‑in form fields to Kit subscriber fields.

Go to the Fields step in the setup flow.
You’ll see Interact fields on the left and Kit field mappings on the right.

3. Click the dropdown on the right of the form field you want to map (None Selected means it is not mapped).

4. Select the Kit subscriber field you want to populate.

⚠️ Default fields (cannot be changed) include Email and First Name.

Step 6. Send a test lead

Before your integration is fully active, you’ll need to send a

This step verifies the connection between Interact and Kit and activates the integration.

Click Send test lead.

2. Fill out all Opt-In Form fields to send as test lead information.

3. (Optional) Navigate to Quiz Data tab to customize test quiz data.

4. Click Send test lead to submit.

5 .Log in to Kit and verify the subscriber was created/updated successfully.

Step 7. Publish your quiz

Any changes you make to your integration won’t be live until your quiz is published.

Before sharing your quiz:

Click Publish in the top-right corner of the quiz editor.
Confirm your changes by clicking Publish changes.

Once published, your Kit integration will be active on the live version of your quiz.

⚠️ Remember: After making changes to your integration or opt-in form, publish all changes to update your live quiz.

FAQs

How does Interact handle existing subscribers in Kit?

When a quiz lead is sent to Kit, Interact checks whether a subscriber already exists based on the email address.

If a subscriber with that email does not exist, a new subscriber is created.
If a subscriber with that email already exists, the existing subscriber is updated with the latest quiz data (sequences/forms, tags, and subscriber fields).

This helps prevent duplicate subscribers and keeps quiz data up to date.

Disable Kit integration for your quiz

If you want to stop sending leads from a specific quiz to Kit, you can disable the integration without disconnecting your Kit account.

Edit the quiz in Interact.
Go to Lead Generation > Integrations.
Navigate to Connect step.
Click Disable.

⚠️ Remember: After making changes to your integration or opt-in form, publish all changes to update your live quiz.

Once disabled, new quiz submissions from this quiz will no longer be sent to Kit. Your Kit account remains connected and other quizzes are unaffected.

❗ Important: After disconnecting an integration from your quiz, your opt-in form will remain disabled until a new or existing integration is connected. Select .csv File Download to keep your opt-in form enabled with no integration connected.
