# Remove multiple products from subscription

Removes multiple product line items from an existing subscription contract in a single request. Products are removed sequentially, allowing partial success if errors occur.

Key Features:
- Sequential processing - items removed one by one
- Partial success allowed - previous removals persist if later ones fail
- Validates each removal against current subscription state
- Smart discount cleanup for line-specific discounts
- Comprehensive validation for each product removal
- Triggers all side effects after each successful removal

Processing Order Matters:
Items are removed in the order provided:
1. First item validated and removed
2. Second item validated against updated state
3. Continue until all processed or error occurs
4. Returns final subscription state

Validation Per Item:
- Line item must exist in subscription
- At least one recurring product must remain
- Build-a-Box min/max quantities maintained
- Minimum cycle commitments honored
- One-time and free products don't count toward minimum

Discount Handling:
When removeDiscount=true:
- Removes discounts applied ONLY to the removed line
- Preserves discounts that apply to multiple lines
- Each removal evaluates discounts independently
- Build-a-Box discounts auto-adjust based on quantity

Side Effects Per Removal:
Each successful removal triggers:
- Activity log entry created
- Customer email sent (except one-time products)
- Shipping price recalculation
- Build-a-Box discount resync
- Product discount adjustments

Partial Success Scenarios:
If removing 3 items and the 2nd fails:
- 1st item: Successfully removed
- 2nd item: Fails, error returned
- 3rd item: Not attempted
- Result: Subscription with 1st item removed

Performance Considerations:
- Each removal is a separate Shopify API transaction
- Multiple emails may be sent to customer
- Consider using single remove for 1-2 items
- Large batches may timeout
- Recommended max: 5-10 items per request

Build-a-Box Handling:
For Build-a-Box subscriptions:
- Validates total quantity after EACH removal
- May fail mid-batch if minimum breached
- Discounts recalculate after each item
- Consider removal order carefully

Important Notes:
- NOT atomic - no rollback on partial failure
- Order of line IDs affects success probability
- Customer receives email per removed item
- All validations apply as if removing individually
- Response shows final state after all attempts
