How to add subscribers to Kit forms from Typeform

There are countless ways to find leads, from website forms to digital ads. But they don't do you much good if they sit collecting dust in your lead generation app. 

With automation, you can level up your email marketing game by automatically connecting your drip email tools like Kit (formerly ConvertKit) to your other business-critical tools. With a simple Zap—Zapier's automated workflows—you can add each new lead you collect in Typeform to the right email list with no extra effort. Here's how.

Before you begin

By default, Kit has a double opt-in system for email subscribers. It’s an industry standard where the subscription is activated after the subscriber clicks a confirmation link from the email. 

This is a great way to make sure that you have consent from the subscribers, and it’s also better for your data and analysis. The open rate from subscribers who double opt-in is higher, plus this process makes sure that you aren’t adding wrong emails or spammers to your database, which can create a misleading analytical picture. 

If you wish to disable this option in Kit for users you're collecting from Typeform, open the form in Kit, and click the Settings icon in the top toolbar. Next, choose Incentive from the sidebar, and enable the Auto-confirm new subscribers option. 

Add subscribers to Kit forms from Typeform

Zapier lets you create automated workflows called Zaps, which send your information from one app to another. You can create your own Zap from scratch without any coding knowledge, but we also offer quick templates to get you started. 

If you'd like to start with a template, click on it below, and you'll be taken to the Zap editor. You'll need to create a Zapier account if you don't already have one. Then, follow the directions to set up your Zap.

Set up your Typeform trigger

First, set up your trigger step—the event that starts your Zap. Search for and select Typeform for your trigger app and New Entry for your trigger event. If you're using the Zap template, these will be selected for you. Next, sign in with your Typeform account, if you haven't already, then click Continue.

Now you'll need to select the form where you're collecting the responses you want to add to Kit. In the Form dropdown, select the appropriate form, then click Continue. 

Now you need to test your trigger. Zapier will find a recent response to your Typeform, which will be used to set up the rest of your Zap. If you don't have any responses to your Typeform, you should submit a sample response before testing your Zap so you can make sure your Zap is working properly.

Once you have at least one response to your form, click Test trigger, select a record, then click Continue with selected record. 

Set up your Kit action

Now it's time to set up your action—the event your Zap performs once it's triggered. If you're using the Zap template, this will be selected for you. Otherwise, search for and select Kit as the action app and Add Subscriber to Form as the action event.

Next, connect your Kit account. If you're doing this for the first time, you’ll need to add Kit's API key to Zapier. 

To find this, open your Kit account, click your profile name in the top-right corner, then select Settings. 

Select Developer in the Settings menu. Then, under the V3 Key section, click the show icon under API Secret to reveal the secret API key. Finally, click the Copy button to copy the API key to your clipboard. 

Back in the Zap editor, sign in to your Kit account. In the new tab, paste in the API you just copied, then click Yes, Continue to Kit.

This will bring you back to the Zap editor, where your Kit account will be connected. Click Continue. 

Now, it's time to set up your action step. First, select the Form in Kit where you want your lead data to go. 

Next, map the data from Typeform that you want to add to Kit. For example, we'll click the + button in the Email field and select the email address we collected from Typeform in the modal. We'll do the same in the First Name field. Once you're done mapping your fields, click Continue. 

Now, click Test Step to test your Zap. If you have the double-opt feature enabled, go to the email Inbox you used for testing this workflow, open the email from ConvertKit, and click Confirm your subscription.

Once you've confirmed your subscription or if you've skipped the double-opt option, you can double check your lead information made it to Kit. Here's what ours looked like:

If everything looks alright, you're ready to use your Zap. Now every time you get a new Typeform submission, the email address will get added to your Kit form, just like that.
