Start with the offer record
SDK & developer platforms should receive context from the offer, checkout, product, price, invoice, and automation path instead of a disconnected form submission.

A useful SDK & developer platforms page should show how the role connects to Offers, checkout, integrations, invoices, API work, webhooks, and post-purchase automation.
SDK & developer platforms should receive context from the offer, checkout, product, price, invoice, and automation path instead of a disconnected form submission.
Operators should be able to inspect Stripe, PayPal, TaxJar, Avalara, test mode, payment options, and connected tools before launch.
Developer and agent-built workflows should use API authentication, SDK checkout, and webhooks rather than hidden scripts or untracked credentials.
Use these internal paths while deciding how SDK & developer platforms should receive checkout, payment, invoice, buyer, and event context.
These resources help connect platform choice to checkout implementation, API work, webhook delivery, security review, and post-purchase operations.
