Setup pattern

One checkout event, multiple systems updated

1. Define the offer and buying surface - Build the offer, product, price, coupon, order bump, upsell, invoice, and checkout mode in Plandalf before HTML or Kit (ConvertKit) receives data.
2. Connect the app roles - Use HTML for its website role and Kit (ConvertKit) for its email role, with Plandalf carrying the commerce context between them.
3. Route the purchase event - Send buyer, product, payment, invoice, deadline, coupon, and fulfilment state into webhooks, API handlers, or sequences after checkout.
4. Keep the operator controls visible - Confirm integrations, payment options, test mode, tax settings, invoices, and automation settings in the app before sending traffic live.

Offer configuration is the source of truth

The HTML and Kit (ConvertKit) integration should start from the offer record: product, price, checkout mode, invoice, and automation context.
