SunLicense

Stripe ​

For selling on your own site with Payment Links or Checkout. A paid checkout issues a license, and the success page shows the key straight away.

Setup ​

  1. SunLicense: Integrations → Stripe → Connect. Map products by Payment Link ID (plink_…) or by a sunlicense_product value you put in the Checkout Session's metadata; or *.
  2. Stripe Developers → Webhooks → Add endpoint: URL = the hook URL. Events: checkout.session.completed, checkout.session.async_payment_succeeded, charge.refunded, charge.dispute.created, charge.dispute.closed, customer.subscription.deleted.
  3. Copy the endpoint's signing secret (whsec_…) into the integration.
  4. Payment Link → After payment → Don't show confirmation page → redirect to the redeem URL with ?session_id={CHECKOUT_SESSION_ID} (the integration page shows it ready to copy). For Checkout, use the same value as success_url.

The buyer lands on the redeem page, which waits a few seconds for the webhook and then shows the key. The Checkout Session ID is unguessable, so no email is asked.

Behaviour ​

Stripe eventSunLicense does
checkout.session.completed (paid) / async_payment_succeededOne license per session
charge.refunded (fully refunded)Revokes; partial refunds keep the license
charge.dispute.createdSuspends; charge.dispute.closed won → reinstates, lost → revokes
customer.subscription.deletedSuspends the subscription's license

Stripe-Signature is verified (HMAC-SHA256, 5-minute tolerance). Test-mode and live-mode endpoints have different secrets: connect one integration per mode.
