# Redeem Promo

`POST /v1/organizations/billing/redeem-promo`

Redeem a promo code on a FRESH org — no Checkout, no card (BACKE-2854).

Ethan directive 2026-07-22: a promo code must let the user continue
without entering a CC. This creates the subscription server-side with the
coupon attached (the self-serve twin of the manual comp flow), stamps
``metadata.organization_id`` so the subscription webhook grants tier +
POC cap, and sets the org's plan fields inline so the user continues
IMMEDIATELY (no webhook-latency paywall).

Only codes whose window bills $0 (percent_off=100 — every POC code by
validated shape) can start service card-less: a partial discount with no
payment method would generate a FAILING first invoice (service cut +
dunning — strictly worse than the card form; the uncollectable shape
POC-PROMO-CAP-2026-07-17 exists to prevent). Partial codes get a clear
redirect to checkout, where the discount still applies. Card-ask happens
at coupon end (finances' T-7d lifecycle).

Every failure carries a reason — never a silent no-op.
