What Are Discount Codes?
Discount codes are promotional tokens that reduce order totals at checkout. They’re ideal for:- Seasonal campaigns: Black Friday, product launches, or anniversaries
- Acquisition offers: First‑purchase incentives or referral rewards
- Retention: Win‑back or loyalty rewards for existing customers
- B2B deals: Contracted or negotiated pricing via private codes
Key Benefits
- Flexible discounts: Percentage or fixed amount off
- Stackable codes: Apply up to 20 codes per checkout, payment, or subscription — combine campaigns (e.g.
WELCOME10+BLACKFRIDAY20) without creating bespoke codes - Targeted control: Restrict by product and subscription cycles
- Campaign governance: Expiration dates and usage limits
- Seamless checkout: UI field and API support via checkout sessions
Creating Discount Codes
Create discount codes in your Dodo Payments dashboard, then apply them in hosted checkout or via API.Dashboard setup
- Discount Name (required): Internal and dashboard display name
- Code (required): The string customers enter at checkout
- Type & Amount (required): Set a percentage or fixed‑amount value, or generate a random code using the button provided
- Expiration Date (optional): Date after which the code becomes invalid
- Usage Limit (optional): Max total redemptions across all customers
- Product Restriction (optional): Limit applicability to selected products
- Subscription Cycle Limit (optional): Number of billing cycles the discount applies to
- Metadata (optional): Attach custom key–value pairs for internal tracking or integrations
Checkout Experience
- Shoppers enter the code in the checkout field.
- Eligible discounts are applied and totals update immediately.
In Checkout Sessions, pass
discount_codes (an array) to pre‑apply one or more codes, and set feature_flags.allow_discount_code to show the input field. Codes are applied in array order, up to a maximum of 20.Stacking Discount Codes
Checkout sessions, payments, and subscriptions accept up to 20 stacked codes via thediscount_codes array (max 20 entries). Codes are applied in array order, so the first eligible code reduces the base price first, the next code reduces the already-discounted price, and so on. The full set of applied discounts is returned in the response under discount_ids (on payments/subscriptions) and discounts (richer per-discount detail, including position and remaining subscription cycles).
The singular
discount_code field is deprecated but still fully supported for backward compatibility — existing integrations continue to work without changes. It cannot be combined with discount_codes in the same request. We recommend migrating to discount_codes (the array form) when convenient, even for single codes, to take advantage of stacking and the richer response shape.API Management

Let customers enter a code at checkout without passing one upfront.Best Practices
- Name clearly: Use recognizable codes that match campaign names
- Time‑box: Add expirations to drive urgency and prevent misuse
- Scope wisely: Limit to specific products to avoid margin leakage
- Validate early: Check code applicability before confirming checkout
- Monitor impact: Track usage and conversion by campaign
Discount codes are powerful levers for acquisition and retention. Start with simple, well‑named offers, validate thoroughly, and iterate based on performance.
