Developer Portal
Minimal portal: integration checklist + links to docs/spec.
1) Connect Stripe
EnsureBack needs your connected Stripe Account ID (Express/Custom) to create Checkout Sessions on your account.
2) Create API Key
Public API uses your API key for authentication (Bearer or x-api-key).
3) Whitelist Websites
Add your checkout domain in Merchant → Developer → Websites. Origin host must match success/cancel host.

When you’re ready, add webhook handling + escrow lifecycle to reflect policy (hold days, dispute rules).
