Get Line Items by ID

Return the items and configurable attributes based on item IDs.

Trim Mode is an optimization feature that reduces the payload size of the GetCartItems API response. Instead of returning the full set of cart item fields, Trim Mode restricts the response to only what is explicitly required.

When enabled, the API response includes these:

A fixed set of 22 default fields (identity, hierarchy, and status)
Fields specified via the fields query parameter
Fields defined in the GCITrimFieldsToInclude field set in Salesforce

All other fields are removed from the response. Structural nodes such as PricebookEntry, Product2, and productChildItemDefinition are always preserved.

Trim Mode applies only to:

getCartItemList
getCartItemListById

See, Enabling Trim Mode

Communication (vlocity_cmt)

For API parameter names and descriptions, see Cart-Based API Swagger Reference.

Response Format	JSON
Resource URL	/services/apexrest/{namespace}/v2/cpq/carts/{cart_ID}/items?id=80236000000Z0QNAA0,01t36000000pfcKAAQ&validate=true

An entire result can be thousands of lines long. This example has been truncated.
If a child line item Id is passed in the input request, then the whole bundle is returned in the response.

To validate or price a bundle, pass the rootItemId instead of the itemId.

Option 1: Per-Request (Recommended for Controlled Adoption)

Enable Trim Mode for specific API calls using a query parameter: /services/apexrest/vlocity_cmt/v2/cpq/carts/{cartId}/items?gciTrimMode=true /services/apexrest/vlocity_cmt/v2/cpq/carts/{cartId}/items?gciTrimMode=true&fields=UnitPrice,vlocity_cmt\_\_OneTimeCost\_\_c

Use this approach for:

Targeted integrations
Specific UI components
Testing and gradual rollout

Option 2: Org-Wide Configuration

Enable Trim Mode globally via CPQ configuration:

Set gciTrimMode = true in CPQ Configuration Setup. This applies to all GetCartItems API calls across the organization.
Configure field set:
- Product2.Name
- UnitPrice
- TotalPrice
- Description All responses include default fields, field set fields, and additional fields via fields parameter (if provided).

Trim Mode removes fields from the API response. Any code, UI, or integration that depends on those fields will break unless the fields are explicitly requested.

API Parameter	Config Setting	Result
TRUE	any	Trim ON
FALSE	any	Trim OFF
not provided	TRUE	Trim ON
not provided	false / unset	Trim OFF

The API parameter always takes precedence. Use gciTrimMode = false to override org-wide settings per request.

These 22 fields are always present when trim mode is on, without needing to request them:

Id, RootItemId, ParentItemId, AssetReferenceId, LineNumber, Product2Id, PricebookEntryId, OrderId, QuoteId, OpportunityId, Quantity, Status, Action, IsRootItem, ProductHierarchyPath, ProductHierarchyGroupKeyPath, BillingAccountId, ServiceAccountId, InCartQuantityMap, CpqMessageData, CpqCardinalityMessage, CpqPricingMessage

/services/apexrest/vlocity_cmt/v2/cpq/carts/{cartId}/items?gciTrimMode=true&fields=Product2.Name,TotalPrice

Returns a lightweight payload (~24 fields vs 150+).

/services/apexrest/vlocity_cmt/v2/cpq/carts/{cartId}/items?gciTrimMode=true&fields=UnitPrice,vlocity_cmt__OneTimeCost__c,vlocity_cmt__RecurringCost__c,vlocity_cmt__OneTimeMargin__c

/services/apexrest/vlocity_cmt/v2/cpq/carts/{cartId}/items?gciTrimMode=false

Returns full response regardless of org settings.
