Operations

Update billing interval for a subscription contract

Request

Updates the billing frequency (how often the customer is charged) for a subscription contract. This comprehensive operation recalculates billing dates, adjusts pricing, updates selling plans, and may also modify delivery intervals.

Key Features:

  • Changes billing frequency while maintaining subscription continuity
  • Automatically adjusts delivery interval when linked to billing
  • Recalculates next billing date based on store settings
  • Reprices all line items for the new frequency
  • Finds and applies matching selling plans
  • Handles anchor day adjustments for consistent billing
  • Validates prepaid subscription constraints

Billing Interval Types:

  • DAY: Daily billing (use with caution)
  • WEEK: Weekly billing (e.g., every 1, 2, 3 weeks)
  • MONTH: Monthly billing (e.g., every 1, 2, 3 months)
  • YEAR: Annual billing

Validation Rules:

  • Cannot set the same interval as current (no-op prevention)
  • For prepaid subscriptions: billing interval must exceed delivery interval
  • Example: Can't bill monthly if delivering weekly (would be paying for 1 delivery but receiving 4)

Next Billing Date Calculation: The system uses sophisticated logic to determine the new billing date:

  1. Starts from current or last successful billing date
  2. Applies store timezone and order time preferences
  3. Ensures date is in the future
  4. Respects day-of-week preferences if configured
  5. May keep current date if 'enableChangeFromNextBillingDate' is false

Side Effects:

  • Delivery Interval: Updated if currently equal to billing interval
  • Line Item Pricing: Recalculated based on new frequency multiplier
  • Selling Plans: Finds and applies best matching plans for products
  • Anchor Days: Updates billing anchor for consistent scheduling
  • Email Notifications: Sends 'ORDER_FREQUENCY_UPDATED' to customer
  • Activity Logs: Records both billing and delivery changes

Prepaid vs Pay-Per-Delivery:

  • Pay-per-delivery: Billing and delivery intervals typically match
  • Prepaid: Customer pays upfront for multiple deliveries
  • This endpoint enforces prepaid logic to prevent undercharging

Authentication: Requires valid X-API-Key header

Query
contractIdinteger(int64)>= 1required

Subscription contract ID to update. Provide the numeric ID without the gid:// prefix

Example: contractId=123456789

Update next billing date for a subscription contract

Request

Reschedules the next billing date for an active subscription contract. This endpoint allows you to change when the next order will be created and processed.

Key Features:

  • Updates the next billing date to the specified date
  • Optionally reschedules all future orders based on the new date
  • Syncs the updated date to Shopify
  • Sends confirmation email to customer

The rescheduleFutureOrder Parameter:

  • true (default): Updates the next billing date AND recalculates all future queued orders based on the new date. Use this to shift the entire billing schedule.
  • false: Only updates the next billing date. Other queued orders remain unchanged. Use this for one-time date adjustments.

Important Notes:

  • The new date must be in the future (with 10 minute grace period)
  • Date is validated against the shop's timezone
  • If anchor days are configured, future orders may align to those anchors

Process Flow:

  1. Validates the contract exists and belongs to the shop
  2. Validates the new date is not in the past
  3. Updates the billing attempt to the new date
  4. Syncs the updated nextBillingDate to Shopify
  5. If rescheduleFutureOrder=true, regenerates the queue from the new date
  6. Sends confirmation email to customer
  7. Records activity log entry

Date Format:

  • Must be ISO 8601 format with timezone
  • Examples: 2024-03-15T12:00:00Z, 2024-03-15T12:00:00+05:30
  • URL encode the date when passing as query parameter

Timezone Handling:

  • The provided date is used as-is for the billing attempt
  • Validation (past date check) uses the shop's configured timezone
  • All dates in the response are in UTC (Z suffix)

Date Restrictions (Customer Portal Only): When called from customer portal context:

  • Minimum days from today (skipDaysFromCurrentDate setting)
  • Maximum days from today (billingDateRestrictToDays setting)
  • External API calls bypass these restrictions

Authentication: Requires valid X-API-Key header

Query
contractIdinteger(int64)>= 1required

Subscription contract ID to update

Example: contractId=123456789
rescheduleFutureOrderboolean

If true (or value not provided), next billing date will be changed and also schedule for future upcoming orders will be changed based on new updated billing date. If false, then only next billing date will be changed, but the schedule for future upcoming orders will not change.

Default true
Example: rescheduleFutureOrder=true
nextBillingDatestring(date-time)^\d{4}-\d{2}-\d{2}T\d{2}:\d{2}:\d{2}(Z|[+-]\d...required

New billing date in ISO 8601 format with timezone. The date must be in the future and may be subject to merchant-configured restrictions. Common formats:

  • UTC: 2024-03-15T12:00:00Z
  • With offset: 2024-03-15T12:00:00+05:30
  • With timezone: 2024-03-15T12:00:00[America/New_York]

The system will convert the date to the shop's timezone for validation.

Example: nextBillingDate=2024-03-15T12:00:00Z
