Lonsdale201 FluentCart Pro licensing
This skill is Pro-only. Verify FluentCart Pro is active and the license module is enabled before using its models, routes, tables, or hooks.
Read licensing-protocol.md before extending generation, activation, update delivery, or client compatibility.
Configure products through the module
Use the Licensing module's product settings and LicenseManager/LicenseHelper services. Do not create keys or activation rows with ad-hoc SQL. The module relates licenses to customer, order, product, variation, subscription, sites, activations, and meta, and applies lifecycle rules to those relations.
Feature-detect ModuleSettings::isActive('license') and Pro classes after fluent_cart/init. A product being downloadable or subscription-based does not itself mean licensing is enabled for that variation.
Follow the commerce lifecycle
The built-in handler generates licenses after fluent_cart/order_paid for initial payment/subscription orders; extends validity on subscription renewal; reactivates where appropriate; and disables/expires/deletes licenses according to payment failure, full refund, validity expiry, order deletion, and module policy.
Listen to license-specific hooks for addon side effects instead of duplicating generation. Make extensions replay-safe: payment/webhook and repair flows may re-enter lifecycle code. Preserve the distinction among active, disabled, and expired plus the stored reason and previous status.
Do not revoke automatically on every transient renewal failure unless that is the explicit access policy. Subscription grace, next billing date, cancellation at period end, EOT, refund, and manual administration are separate decisions.
Treat credentials and activations as bearer authority
License keys and activation hashes are secrets. Never log them in full, expose them in public REST serializers, place them in analytics/referrers, or accept a license ID alone as authorization. Normalize the site URL through LicenseHelper and validate product/item binding on every check, activation, deactivation, version, and package request.
Activation must be concurrency-safe around the limit. Test simultaneous first activations and activation/deactivation races; a read-count-create-recount sequence alone is not proof of atomic enforcement.
Customer-profile endpoints require WordPress login and must remain scoped to the resolved FluentCart customer. Admin endpoints use LicensePolicy permissions such as licenses/view, licenses/manage, and licenses/delete.
Use the public protocol as installed
License client calls enter FluentCart's public action dispatcher and map to check_license, activate_license, deactivate_license, get_license_version, and download_license_package handlers. Match the installed request/response shape and distinguish transport HTTP success from the returned license status/error.
Do not reuse fct_package as a general-purpose signed URL scheme. In the tested 1.6.0 source it is a base64-encoded credential payload, and the download parser does not consume the appended expiry field as a verified cryptographic claim. Use the built-in path only for required compatibility, keep TTL/authorization under version-specific audit, and implement new protected delivery with a server-held, tamper-evident, expiring token or opaque one-time record.
Protect package and update delivery
- Store packages outside direct public access or behind controlled storage.
- Resolve the current entitled product/variation and valid activation again at download time.
- Validate expiry server-side and prevent path traversal/open redirects.
- Stream or redirect using the storage driver's safe contract.
- Rate-limit checks, activation, version and package endpoints.
- Avoid leaking whether arbitrary keys or customer emails exist.
- Record redacted audit events and provider/client version for reconciliation.
Test matrix
Test disabled module/Pro absence, one-time and subscription products, quantity and variation license settings, duplicate paid event, payment failure, full and partial refund, renewal/grace/expiry/EOT/reactivation, key regeneration, limit change, local/staging classification, normalized URL variants, concurrent limit race, activation replay, wrong item/site/hash, customer cross-account access, admin capability boundaries, expired/tampered package URL, update response, and legacy EDD client compatibility.
