Wires the second source-adapter (Gumroad) plus the email delivery
that lets the server fulfill a sale end-to-end without operator
intervention.
Auth model: Gumroad doesn't HMAC the body, so we use their
recommended URL-secret pattern (?secret=...). Wrong/missing secret
returns 404 — no signal to a prober that the endpoint exists.
Webhook flow (server/app/routes/webhooks.py):
1. audit-log the raw payload (gumroad_events row) BEFORE anything
else, so a later failure leaves us replayable
2. parse via GumroadAdapter (server/app/adapters/gumroad.py)
3. mint_from_sale — UNIQUE(source, source_order_id) dedups
duplicate webhook retries
4. send the license email
5. mark gumroad_events.processed = true
Always returns 200 once auth passes. Non-2xx would trigger Gumroad's
3-day retry storm; we'd rather record the failure on the audit row
and replay manually after fixing whatever surfaced.
Product → tier mapping is per-source YAML at
server/config/products.yaml (lru_cached). Adding a SKU = edit yaml,
restart api. Unmapped product_id is an error on the audit row, not
a crash.
EmailService (server/app/email.py): provider-agnostic interface with
Postmark as the first implementation. When POSTMARK_TOKEN is unset
the factory returns LoggingEmailService instead, so the webhook
exercises end-to-end before Postmark is provisioned.
48 unit tests (was 21) including:
- Gumroad secret verify with constant-time compare
- Sale parsing: amount-in-cents, name fallback from email,
test=true tagging, missing-required fields, offer codes
- Product mapping lookups
- Email rendering text + HTML, HTML-escapes user input
- Postmark client via httpx.MockTransport (success and 4xx)
- Webhook end-to-end: secret check, audit log, idempotency on
retry, unmapped product, email failure keeps license
Smoke test (server/scripts/smoke.sh) extended to POST a synthetic
Ping payload, verify the row + audit log, prove wrong-secret is
rejected, prove duplicate sale_id stays one row.
SQLite-test compatibility:
- BigInteger primary key uses with_variant(Integer, "sqlite") since
SQLite only autoincrements INTEGER PRIMARY KEY.
- python-multipart pulled in for FastAPI Form parsing.

# Storefront product → license tier mapping.
|
|
#
|
|
# Each storefront has its own product/variant IDs. The webhook
|
|
# handler looks up (source, product_id) in this file to decide
|
|
# what to mint. Unknown product IDs are an error (audit row gets
|
|
# error="unmapped product", no license created — the operator
|
|
# fixes the mapping and replays).
|
|
#
|
|
# After editing this file, `docker compose restart api` to reload.
