Get product swap variant groups for a contract

Request

Retrieves product swap variant groups for the next 10 billing cycles of a specific subscription contract. This endpoint calculates and returns which products will be swapped to in future billing cycles based on configured swap automations.

Response Structure: Returns a 2D array (List<List>):

  • Outer array: Represents the next 10 billing cycles
  • Inner arrays: Contains the variant(s) that will be swapped to for that specific cycle
  • Index 0: Variants for the next (upcoming) billing cycle
  • Index 1: Variants for the cycle after that
  • And so on for the next 10 cycles

Variant Details: Each variant object includes:

  • variantId: Shopify variant ID
  • quantity: Number of units to swap
  • title: Variant title (e.g., "Medium Roast - 12oz")
  • image: Product/variant image URL
  • productTitle: Full product name
  • productId: Shopify product GID
  • variantTitle: Full display name combining product and variant titles
  • swapId: ID of the swap automation rule that triggered this swap

How It Works:

  1. Takes the current products in the subscription
  2. Applies configured swap automations for the next 10 cycles
  3. Calculates which products will be swapped based on:
    • Billing cycle number
    • Swap rule configurations (forBillingCycle, checkForEveryRecurringOrder)
    • Rule sequence/priority
  4. Returns the projected product lineup for each cycle

Use Cases:

  • Preview upcoming product swaps in customer portals
  • Show customers their subscription product timeline
  • Build interactive swap calendars
  • Display "what you'll receive" for future orders
  • Debug and verify swap automation configurations

Important Notes:

  • Returns 10 cycles even if no swaps are configured (returns current products)
  • Multiple variants in an inner array means multiple products will be in that order
  • Empty inner arrays indicate no products for that cycle (rare edge case)
  • The swapId can be used to trace which automation rule triggered the swap

Get all one-time products for a subscription contract

Request

  • Returns ALL one-time products across all queued billing attempts
  • Each product includes the billing attempt ID to identify which order it belongs to
  • Includes product details: variant ID, quantity, title, image, and price
  • Products are automatically removed after the associated billing attempt is processed

Use Cases:

  • Display all one-time products added to a subscription across all upcoming orders
  • Allow customers to review their one-time add-ons in customer portal
  • Enable merchants to see all one-time products for a contract
  • Integrate with external systems to manage subscription add-ons
