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 Postmark or Customer.io receives data.
- 2. Connect the app roles - Use Postmark for its email role and Customer.io 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.
