> Post buyer events to a Slack channel next to the Kit tag step, or post a Slack message when someone joins a Kit form. Native Plandalf steps, no Zapier. Source: https://plandalf.com/apps/convertkit/integrations/slack Last modified: 2026-10-26 Native integration # Kit (ConvertKit) + Slack integration Tell your team in Slack when a buyer is tagged in Kit, or when a Kit tag or form signup happens.

No coding required. **Kit (ConvertKit)** **Slack** ## Does Kit (ConvertKit) integrate with Slack? Kit does not post to Slack through Plandalf on its own. Plandalf runs both sides: a paid-checkout sequence can tag the buyer in Kit and send a Slack message, and a Kit trigger such as Tag Added or Subscriber Joined Form can start a sequence that posts to Slack. Both are connected under Automation, Marketplace. ## What moves between Kit (ConvertKit) and Slack Event From and to Through What happens Checkout completed PlandalfKit Native step Tag Subscriber adds the Customer tag and creates the subscriber if Kit has not seen the email. Checkout completed PlandalfSlack Native step Send Slack Message in the same sequence posts a line such as the buyer's name and what they bought. The message can read `{{trigger.line_items_summary}}`. Subscriber joined form KitSlack Native step Plandalf adds the Kit webhook when you save the trigger. The sequence then posts to a channel, for example when someone joins a high-intent landing page. Tag added KitSlack Native step Pick the Tag on the trigger to fire for one tag only, so Slack hears about VIP tags and not every tag change. Invoice refunded StripeSlack Native step The Slack notifications recipe posts every refund, partial ones included. The Kit tag removal in the refund template runs only on full refunds by default. ## Tag in Kit and post to Slack from one sequence You need a Kit V4 API key, permission to add apps to your Slack workspace, and a Plandalf checkout. 1. ### Connect Kit In Automation, Marketplace, choose Kit and paste the V4 key from Settings, Developer. Use the V4 key, not the legacy V3 one. 2. ### Connect Slack Choose Slack, click Add to Slack and Allow. No API key is needed. For a private channel, add the Plandalf app to the channel in Slack first. 3. ### Build the buyer sequence Create a sequence on Plandalf, Checkout Completed. Add Kit, Tag Subscriber with `{{trigger.customer_email}}` and a Customer tag. 4. ### Add the Slack message Add Slack, Send Slack Message after the Kit step and choose a channel. Write it in Slack formatting, for example `*{{trigger.customer_first_name}}* just joined the list as a customer`. 5. ### Add a Kit-triggered alert Create a second sequence with Kit, Tag Added to Subscriber as the trigger and a specific tag. Its only step posts to a channel for your sales team. 6. ### Test and watch failures A step test posts for real, so tell the channel first. In My apps switch on Post automation failures to Slack so a failed Kit step shows up there. ## What sellers do with Kit (ConvertKit) and Slack ### Founder-led course sales A course creator watches a Slack channel for each sale and sees at the same time that Kit has tagged the buyer, so a welcome note can follow. ### Waitlist hot signals A launch team posts to a Slack channel when someone joins a specific Kit form, so the person who replies to leads knows who just joined before the offer opens. ## Limits and gotchas - Kit allows 120 requests a minute per key. A rate-limited step is retried twice, and a failed alert is posted to Slack only if you switch that on. - If Slack refuses a message, the step still finishes and its output shows a failed status with Slack's error code. Check the Events view. - A private Slack channel is missing from the list until the Plandalf app is added to it. - Purchases do not appear in Kit's purchase history. The Slack message is the easy place to read the order summary. - Slack alerts for failed runs go out at most once every 15 minutes per sequence, and only while failed automation notifications are on. ## Kit (ConvertKit) and Slack: common questions Does Kit (ConvertKit) integrate with Slack? Plandalf connects them through sequences. A Kit trigger can start a Slack post, and a paid checkout can run Kit and Slack steps together. Check Kit's own integrations list for a direct link. How do I get a Slack message when someone joins a Kit form? Build a sequence with Kit, Subscriber Joined Form as the trigger and Slack, Send Slack Message as the step. Plandalf adds the Kit webhook when you save. Can Slack tell me when a Kit step fails? Yes. Switch on Post automation failures to Slack on your Slack connection and pick a failure alert channel. Is there a Kit ConvertKit Slack notification for refunds? The Slack notifications recipe has a Refund event that posts the amount refunded. The Kit tag is removed by the refund template, which is a separate sequence. ## Guides for this pair - [Plandalf with Kit (ConvertKit)](https://plandalf.com/platforms/convertkit) - [Plandalf with Slack](https://plandalf.com/platforms/slack) - [Kit setup](https://plandalf.com/docs/integrations/kit) - [Slack setup](https://plandalf.com/docs/integrations/slack) - [Automations overview](https://plandalf.com/docs/integrations/plandalf) [Start your 14-day free trial](https://admin.plandalf.dev/signup) ## More from Kit (ConvertKit) and Slack - [**Flodesk + Kit (ConvertKit)**Flodesk segments can start Kit tags and sequences through a Plandalf catch URL, and a checkout can write the buyer to both.](https://plandalf.com/apps/flodesk/integrations/convertkit) - [**Kajabi + Kit (ConvertKit)**One paid checkout grants the Kajabi offer and tags the buyer in Kit, from a single Plandalf sequence.](https://plandalf.com/apps/kajabi/integrations/convertkit) - [**Klaviyo + Kit (ConvertKit)**Kit gets native Plandalf steps, Klaviyo gets a webhook call to its API, and one checkout can feed both.](https://plandalf.com/apps/klaviyo/integrations/convertkit) - [**PayPal + Slack**Sales paid by PayPal on a Plandalf checkout can post to a Slack channel, so your team sees each order as it lands.](https://plandalf.com/apps/paypal/integrations/slack) - [**Stripe + Slack**Your team sees each Stripe sale, renewal, upsell and refund in a Slack channel, and failed automations are reported there as well.](https://plandalf.com/apps/stripe/integrations/slack) - [**Mailchimp + Slack**Slack hears about Mailchimp subscribes, unsubscribes and new buyers, and Mailchimp is updated from the same sequence.](https://plandalf.com/apps/mailchimp/integrations/slack) Checked October 26, 2026 against Plandalf's own setup guides.
