Klaviyo's own Shopify connection covers the store's customers, orders and onsite events. A Plandalf offer opened from a Shopify page can write its buyers into Klaviyo with Send Webhook (to Klaviyo's Events or profile API) or through Zapier. ## What moves between Shopify and Klaviyo Event From and to Through What happens Offer opened from a Shopify page ShopifyPlandalf Checkout embed A theme button carrying `data-plandalf-present` opens the offer. The cart keeps running as normal, and the offer is paid through your own Stripe or PayPal account. Checkout completed Plandalf (paid via Stripe)Klaviyo Webhook Send Webhook POSTs to Klaviyo's Create Event endpoint with a metric name you choose and the buyer's email as the profile. Klaviyo answers 202 once the event is validated and queued, which is not the same as processed. Checkout completed Plandalf (paid via Stripe)Klaviyo Webhook To store first name and your own properties, a second Send Webhook can call Klaviyo's profile-import endpoint, which creates the profile or updates the existing one. Upsell accepted Plandalf (paid via Stripe)Klaviyo Webhook Use a different metric name for the upsell so a Klaviyo flow can tell a plain buyer from one who took the add-on. Cart recovery PlandalfKlaviyo Webhook When a payment fails, the trigger carries a `retry_url`. Passing it as an event property lets a Klaviyo email link the buyer back to the payment page. Profile enters a flow KlaviyoPlandalf Webhook Plandalf's Klaviyo page uses a Webhook action inside a Klaviyo flow that posts to a Plandalf catch URL, so the sequence can run Enroll in Promo for that person. ## Send a Plandalf checkout buyer to Klaviyo as an event You need a Shopify theme you can edit, a published Plandalf offer and a Klaviyo private API key with write access to events. 1. ### Load the SDK in the Shopify theme Add the Plandalf script before the closing `body` tag of `theme.liquid`. Place a button with `data-plandalf-present` on the product template, then test that the Shopify path still works before you test the offer. 2. ### Create a Klaviyo private key Klaviyo's Create Event reference says the endpoint takes a private key with the `events:write` scope, sent as an Authorization header that starts with Klaviyo-API-Key. Profile import needs `profiles:write`. Create a key with only the scopes you use. 3. ### Build the sequence Under Automation, then My Sequences, create a sequence with Plandalf, Checkout Completed and your offer. Pick a recent checkout on the Test tab so `{{trigger.customer_email}}` and the other variables show real values. 4. ### Configure Send Webhook for the event Add Send Webhook, POST, to `https://a.klaviyo.com/api/events`. Add the Authorization header, a `revision` header with a dated revision from Klaviyo's reference, and set Content-Type to `application/vnd.api+json`, because Plandalf only defaults to application/json when you leave it blank. 5. ### Write the payload Follow Klaviyo's body shape: a `data` object of type event whose attributes hold the properties, a metric with a name such as Plandalf Checkout Completed, and a profile with `email` set to `{{trigger.customer_email}}`. Add `{{trigger.line_items_summary}}` as a property. 6. ### Test, then handle refunds Turn on Run on test purchases, buy with a test card and your own email, and confirm the event on the profile in Klaviyo before turning the sequence on. For refunds, add a sequence on Invoice Refunded that sends a refund event; Klaviyo's reference says setting `backfill` to true records an event without starting flows. ## What sellers do with Shopify and Klaviyo ### Upgrade offer on a product launch A store launches a product in the Shopify cart and sells a paid early-access pass as a Plandalf offer from the same page. Klaviyo gets a Plandalf event per pass buyer, and a flow built on that metric sends the access emails. ### Bookings next to a retail catalogue A shop that also sells fittings or classes keeps the bookable service in a Plandalf offer. Each booking becomes a Klaviyo event, so the confirmation and reminder flow sits with the rest of the store's email. ## Limits and gotchas - This route is built from Klaviyo's published reference and Plandalf's Send Webhook options, and Plandalf's docs do not show a worked Klaviyo example. Run the step on the Test tab with your own email before relying on it. - The Klaviyo key is a private key held in the step's headers. Create it with only the scopes needed, and rotate it in the sequence if it ever leaks. - Klaviyo's Shopify connection brings in Shopify orders and onsite events, none of which exist for a Plandalf sale. Revenue from Plandalf appears in Klaviyo only if you pass it as an event property. - Klaviyo's Create Event reference lists a steady limit of 3,500 requests a minute and a burst of 350 a second, which a normal launch will not reach. - Send Webhook waits up to 30 seconds for a reply and Plandalf's docs say not to assume automatic retries, so read the step result in the Events view. ## Shopify and Klaviyo: common questions Does Shopify integrate with Klaviyo? Yes, Klaviyo has its own Shopify connection, set up from Klaviyo's Integrations page, which brings in store customers, orders and onsite events. Plandalf is not part of that connection. How do I connect Plandalf to Klaviyo for a Shopify store? Open the offer from a Shopify page, then build a sequence on Checkout Completed whose Send Webhook step posts a purchase event to Klaviyo's Events API. The recipe above lists each field. Shopify Klaviyo integration: will a Plandalf sale count as a Shopify order? No. A Plandalf offer is paid through your Stripe or PayPal account, so Shopify holds no order for it and Klaviyo's Shopify data will not include it. Can a Klaviyo flow start a Plandalf promo countdown? Yes, through a Webhook action in the flow that posts to a Plandalf catch URL, as described on Plandalf's Klaviyo page. The sequence then runs Enroll in Promo. ## Guides for this pair - [Plandalf with Shopify](https://plandalf.com/platforms/shopify) - [Plandalf with Klaviyo](https://plandalf.com/platforms/klaviyo) - [Shopify setup guide](https://plandalf.com/docs/platforms/shopify) - [Webhooks, inbound and outbound](https://plandalf.com/docs/api/webhooks) - [Automations overview](https://plandalf.com/docs/integrations/plandalf) [Start your 14-day free trial](https://admin.plandalf.dev/signup) ## More from Shopify and Klaviyo - [**Stripe + Shopify**A button in your Shopify theme opens a Plandalf checkout that charges through your own Stripe account, while Shopify keeps its cart and catalog.](https://plandalf.com/apps/stripe/integrations/shopify) - [**PayPal + Shopify**A Plandalf offer sits beside the Shopify cart.
