}Discount Codes
Create a discount code
Mint a promo code. It is redeemed at checkout · carried by the session as discountCode, applied on its own when preApply is set, or typed by the payer · and always re-validated and re-priced server-side. A payer never sets an amount.

Headers
Optional key (≤255 chars, e.g. a UUID v4) making this POST safe to retry · the response is cached 24h and a retry with the SAME key replays it instead of re-executing. The same key with a different body → 422 IDEMPOTENCY_KEY_CONFLICT; a retry while the first is in flight → 409.
Maximum string length:
255Example:
"5f3b9c2e-1a4d-4f2b-9c31-7e2a1b6d8c04"
Body
application/json
Only the field matching discountType is stored; the other is cleared, so a code can never carry two contradictory discounts.
The code you hand out. Unique per account and environment.
Required string length:
2 - 40Pattern:
^[A-Z0-9][A-Z0-9_-]*$Example:
"NOEL2026"
Available options:
PERCENTAGE, FIXED Required when discountType=PERCENTAGE.
Required range:
1 <= x <= 99Required when discountType=FIXED. Minor units as a string of digits.
Pattern:
^[1-9]\\d*$Example:
"500"
Required when discountType=FIXED.
Pattern:
^[A-Z]{3}$Eligible products. Leave empty to apply to every product.
Global redemption cap. Null = unlimited. Counts settled redemptions plus checkouts in flight, so the last use is never handed to two buyers; an abandoned attempt releases its slot on expiry.
Required range:
x >= 1Apply on the hosted checkout with no payer input, on every order it covers. A code carried by the session wins over it. The payer sees the discount already deducted and can still remove it; one that no longer redeems is silently skipped rather than raising an error they did not cause.
