Native integration
Stripe takes the payment, Plandalf runs the checkout, and Kit tags the buyer and starts their emails from the paid order.
No credit card required. No coding required.
Stripe
Kit (ConvertKit)Not as a direct sync between the two accounts. Plandalf sits between them: a Plandalf checkout takes payment through your connected Stripe account, and a Plandalf sequence then runs native Kit steps to tag the subscriber, add them to a form or sequence and update custom fields. A Kit event, such as a tag being added, can also start a Plandalf sequence.
| Event | From and to | Through | What happens |
|---|---|---|---|
| Checkout completed | Plandalf (paid via Stripe) → Kit | Native step | A paid main checkout starts the sequence. Its Kit steps create the subscriber first if Kit does not have the email, so no separate create step is needed. |
| Upsell accepted | Plandalf (paid via Stripe) → Kit | Native step | A customer who pays for the post-checkout upsell can get a second tag, so Kit can tell bundle buyers from single-product buyers. |
| Invoice paid | Plandalf (paid via Stripe) → Kit | Native step | Also fires on subscription renewals and invoices you send, which makes it the place to update a custom field such as plan. |
| Cart abandoned | Plandalf → Kit | Native step | A visitor who typed an email but did not pay can be added to a Kit form or sequence after a wait of 5 minutes to 7 days. The trigger can skip visitors from the EU, EEA and UK. |
| Invoice refunded | Stripe → Kit | Native step | A refund that succeeds in Stripe, including one made in the Stripe dashboard, starts the Remove access on refund template, which removes the Kit tag. |
| Subscriber joined form, tag added | Kit → Plandalf | Native step | Plandalf adds the webhook to your Kit account when you save the trigger. A common use is the Enroll in Promo step, which starts a countdown for anyone who joins a form. |
You need a Stripe account and a Kit account where you can create API keys.
In Plandalf, authorize your Stripe account (you are sent to Stripe and back, and Plandalf never sees your secret key), attach a Stripe-backed price to an offer and publish it. Money still lands in your Stripe account.
In Kit open your account menu, then Settings, then Developer. Under V4 Keys choose Add a new key and name it Plandalf. Use the V4 key, not the legacy V3 key on the same page.
Go to Automation, then Marketplace, find Kit under Available now and click Connect. Paste the key. Plandalf checks it with Kit straight away and shows Kit connected.
Create a sequence under My Sequences, choose Plandalf as the app and Checkout Completed as the trigger, and pick the checkout under Offer. On the Test tab choose a recent checkout as the sample so the variable menu fills in.
Add Kit, Tag Subscriber with Email Address set to {{trigger.customer_email}}, a tag such as Customer and First Name set to {{trigger.customer_first_name}}. Then add Kit, Add Subscriber to Sequence with the same email and your onboarding sequence, which must be active in Kit.
Under Automation, then Templates, add Remove access on refund for the same checkout and pick your tag in the Remove Tag from Subscriber step. The trigger is Invoice Refunded with Full refunds only switched on.
Turn on Run on test purchases in the sequence settings, buy through the checkout's test link with a Stripe test card, check the Events view and your Kit subscriber, then switch the setting off. Testing a step changes real data in Kit, so use your own email.
One checkout, one sequence: Checkout Completed tags the buyer Customer and drops them into the welcome sequence you built in Kit. A second sequence on the same trigger, limited to a different offer, tags buyers of a higher tier separately.
Sellers who run a bump or an upsell add a second sequence on Upsell Accepted that applies an Upsell tag. In Kit that tag becomes a segment for follow-up emails about the add-on.
People who join a Kit form start a Plandalf sequence with Enroll in Promo, so each person gets their own countdown. When they pay, the Checkout Completed sequence tags them and Kit knows who bought.
