The offer record connects the stack
Use Offers to define the product, price, checkout mode, invoice, and automation context before HTML and Kit (ConvertKit) receive events.
Integration pair
HTML + Kit (ConvertKit)
Use HTML and Kit (ConvertKit) together with Plandalf as the layer that ties checkout, payments, invoices, integrations, and lifecycle automation together.
Common setup
Most teams use HTML as their website layer and Kit (ConvertKit) as their email layer, with Plandalf in the middle handling the checkout, Offers, invoices, integrations, and the events that fire after a purchase.
See HTML and Kit (ConvertKit) docs for connection details.
Product surfaces behind this integration
This legacy integration URL now points builders toward the same product reality as the canonical app-pair guide: Offers, payment options, invoices, integrations, Automations, API docs, and webhooks.
Purchase automation carries the details
Automations and webhooks let HTML and Kit (ConvertKit) receive buyer, product, payment, invoice, coupon, and deadline context.
