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 TaxJar or beehiiv receives data.
2. Connect the app roles - Use TaxJar for its tax role and beehiiv 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.
