# Redeem Promo

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

## Request

- Base URL: `https://api.mixpeek.com`
- URL: `https://api.mixpeek.com/v1/organizations/billing/redeem-promo`
- Auth: HTTP bearer

Redeem a promo code on a FRESH org — no Checkout, no card.

A promo code lets you continue without entering a card. 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.

## Request body

- RedeemPromoRequest

  - `plan` string: Plan slug to start on the comped window (product_tier, e.g. managed_build). Must be self-serve and match the code's product restriction.

    - `building` string, nullable: What are you building?
    - `referral_source` string, nullable: How did you hear about Mixpeek?
