Membership Contracts

Create and add custom discount to subscription

Creates a custom discount and applies it to a subscription contract. This endpoint allows you to create on-the-fly discounts without requiring pre-existing discount codes in Shopify.

Discount Creation & Application:

Custom Discount: Creates discount directly on subscription contract
Flexible Types: Supports percentage off or fixed amount off
Cycle Limits: Optional limit on number of billing cycles discount applies
Item-Level Control: Option to apply discount to each item vs entire order
Immediate Effect: Discount applies to next billing cycle

Discount Parameters:

Percentage: Percentage discount (e.g., 15 for 15% off) - use for discountType=‘PERCENTAGE’
Amount: Fixed amount discount (e.g., 10.00 for $10 off) - use for discountType=‘FIXED_AMOUNT’
Title: Display name for the discount (e.g., ‘Loyalty Discount’)
Cycle Limit: Number of billing cycles discount applies (null = unlimited)
Applies On Each Item: true = per-item discount, false = order-level discount

Discount Types:

PERCENTAGE: Percentage-based discount (use ‘percentage’ parameter)
FIXED_AMOUNT: Fixed dollar amount discount (use ‘amount’ parameter)

Cycle Limit Examples:

recurringCycleLimit=1: Discount for first order only
recurringCycleLimit=3: Discount for first 3 orders
recurringCycleLimit=null: Discount applies forever

Use Cases:

Customer retention offers (e.g., 20% off next 3 orders)
Loyalty rewards and point redemptions
Win-back campaigns with limited-time discounts
Customer service compensation discounts
Referral program rewards
First-order discounts for new subscribers
Seasonal promotions on existing subscriptions

Example Scenarios:

Retention Offer: 25% off for 2 billing cycles
- percentage=25, recurringCycleLimit=2, discountType=‘PERCENTAGE’
Loyalty Reward: $5 off every order forever
- amount=5.00, recurringCycleLimit=null, discountType=‘FIXED_AMOUNT’
First Order Deal: 50% off first order only
- percentage=50, recurringCycleLimit=1, discountType=‘PERCENTAGE’

Returns: Updated subscription contract object with discount applied

Authentication: Requires API key authentication via X-API-Key header or api_key parameter
