Connect Gravity Forms to Kit (formerly ConvertKit)
Connect Gravity Forms to Kit, the email platform formerly known as ConvertKit, and every form submission becomes a subscriber in the Kit form you choose. The free ClickSyncr for Kit plugin adds a native Gravity Forms feed add-on: connect your v4 API key once, pick a Kit form, map your fields, save. So there is no code, and it takes about two minutes per form.
Before you begin
You need three things: the ClickSyncr for Kit plugin activated, Gravity Forms active, and a Kit account (free accounts work, including accounts from the ConvertKit era) with permission to create a v4 API key. You store the key once, and every supported builder on the site then shares it.
Get your Kit v4 API key
- Log in to Kit and open your account settings, then go to the Developer (API Keys) section.
- Create a v4 API key. Accounts from the ConvertKit era work the same way.
- Copy it and paste it into any ClickSyncr Kit panel. One key serves the whole site, and free Kit accounts work.
Treat the key like a password. Anyone holding it can read and modify your Kit subscribers.
Gravity Forms setup, step by step
- Open the form’s settings and find ClickSyncr Kit. From Forms, edit a form and open Settings. ClickSyncr Kit appears in the settings menu as a feed add-on, the same pattern as every Gravity Forms integration.
- Create a feed and connect your Kit v4 API key. Also, you store the key once for the whole site, so other forms and builders then share the connection.
- Choose the Kit form. In fact, the dropdown lists every form in your Kit account, so each WordPress form can feed a different Kit form.
- Map your form fields. Then Email is the required mapping; first name and every custom field in your Kit account load automatically once the key connects.
- Optional: set a consent field. Also, choose a checkbox, acceptance or radio field to drive opt-in. Ticked adds the subscriber to the Kit form you chose; unticked saves them in Kit as a subscriber only, without joining the form, so no form emails or automations fire.
- Save the feed. In addition, every submission that passes the feed now syncs.
Email, first name, and custom fields
Kit identifies subscribers by email, so Email is the one required mapping. First name has its own field, and every custom field in your Kit account loads automatically once the key connects, ready to receive any other form input. Also, ClickSyncr simply skips an unmapped field and never overwrites existing subscriber data with a blank value. Because subscribers are matched by email, a repeat submission updates the existing subscriber instead of creating a duplicate.
Double opt-in, the Kit way
Kit handles confirmation at the form level: each Kit form carries its own incentive email and double opt-in settings inside Kit. ClickSyncr subscribes the visitor to the Kit form you chose, and your form’s own settings decide whether a confirmation email goes out first. That means your opt-in behaviour stays exactly where Kit users expect to manage it.
Verify the sync
First, submit the form on the front end (not the admin preview) with a test address you can recognise, filling every mapped field. Then, in Kit, open Subscribers and confirm the subscriber exists with the mapped values, and check the Kit form’s own reporting for the new entry. In short, that one minute catches almost every configuration mistake.
Troubleshooting
| Symptom | Cause and fix |
|---|---|
| The Kit form dropdown is empty | The key is missing or mistyped, or it is not a v4 key. Create a v4 API key in Kit’s Developer section, re-paste it and reconnect. |
| Submissions do not appear in Kit | Nine times out of ten the Email field is not mapped. It is the one required mapping. Fix it, then submit a fresh test. |
| A new Kit form or custom field is not listed | The catalog is cached briefly. Use the refresh control in the Gravity Forms settings. |
| The subscriber syncs but a field is empty | Either that field is unmapped, or it was blank on the submission. ClickSyncr skips empty values, so they never wipe existing Kit data. |
| The subscriber shows as unconfirmed in Kit | Your Kit form has double opt-in enabled, so Kit sent a confirmation email first. The Kit form’s own settings control that, not the plugin. |
Is this a Gravity Forms feed add-on?
Yes. ClickSyncr for Kit registers a standard Gravity Forms feed add-on, so feeds behave exactly like the Gravity Forms integrations you already know.
Do I need a specific Gravity Forms license?
Any license tier works. The plugin only needs Gravity Forms itself active on the site.
