The offer record connects the stack
Use Offers to define the product, price, checkout mode, invoice, and automation context before PayPal and Customer.io receive events.
Integration pair
PayPal + Customer.io
Use PayPal and Customer.io together with Plandalf as the layer that ties checkout, payments, invoices, integrations, and lifecycle automation together.
Common setup
Most teams use PayPal as their payment layer and Customer.io as their email layer, with Plandalf in the middle handling the checkout, Offers, invoices, integrations, and the events that fire after a purchase.
See PayPal and Customer.io 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.
Payment options stay tied to checkout
PayPal and Customer.io should not split payment state from invoices, tax settings, or post-purchase events.
Purchase automation carries the details
Automations and webhooks let PayPal and Customer.io receive buyer, product, payment, invoice, coupon, and deadline context.
