On success call the existing lookup helper, which uses a bound parameter; never build SQL text from the value. Tests: injection payload never reaches the DB and returns 200 + warning; wrong-type string returns 200 + warning; valid ID hits the existing lookup guard paths. (recommended) (human ~2h / CC ~10 min)\n \u2705 No SQL text is ever built from external input, so injection is impossible by construction\n \u2705 Malformed IDs return 200 with a correlated warning instead of 72h of retries\n \u2705 Reuses the existing lookup helper and its not-found guard; no duplicated query\n \u274c Needs the primary-key type confirmed and one small validation step with its tests\n2B) Bound parameter only, no shape validation (human ~1h / CC ~5 min)\n \u2705 Closes the injection vector with a single change to how the query is built\n \u2705 Reuses the existing lookup helper as-is\n \u274c A non-ID string still raises a type-cast DB error, which the wrapper turns into a 500 and Stripe retries for 72 hours; the log says \"DB failure\" not \"bad input\"\n2C) Keep the raw SQL fragment as written (human 0 / CC 0)\n \u2705 No work\n \u2705 Matches the sketch\n \u274c Live SQL injection on the payment path; the plan's own contract text says the input is unsanitized\nNet: reject bad input loudly and bind good input, versus trusting a string because Stripe signed the envelope.
