For Agents
Create, read, update, archive, search, and upsert HubSpot Commerce cart records, including line item associations and contact links for abandonment workflows.
Use for: I need to create a cart record in HubSpot from a storefront event, Retrieve a cart by its CRM object ID, Search for abandoned carts older than 24 hours, Update the status of a cart to converted or abandoned
Not supported: Does not process payments, manage inventory, or render storefront UI — use only for HubSpot CRM cart object records.
The HubSpot Carts API manages cart records inside HubSpot Commerce, representing in-progress purchases that can be associated with contacts, line items, and deals. It exposes the standard CRM v3 object pattern — read, create, update, archive, search, and batch upsert — so cart state from a storefront can be synced into HubSpot for marketing, abandonment workflows, and reporting. Each cart can carry custom properties, line item associations, and currency information.
Install Jentic One Beta
Connect the Carts to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Carts, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.
Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine
# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh2
Step 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register # connects your agent to your Jentic One instanceJentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.
Capabilities
What an agent can do with Carts API.
Create cart records with associated contacts, line items, and currency properties
Batch upsert carts by an external storefront id to keep HubSpot in sync without duplicates
Search carts by contact, status, or last-modified date using filter groups
Retrieve a single cart with its associated line items and contact in one call
Update cart properties (status, total, currency) as the storefront state changes
Archive completed or abandoned carts in batch to keep active CRM views clean
Page through all carts for export or warehouse sync
Use Cases
Patterns agents use Carts API for, with concrete tasks.
★ Storefront Cart Sync
Sync cart state from a custom storefront into HubSpot Commerce so marketing automation can target abandoned carts. The batch upsert endpoint handles up to 100 carts per request keyed on the storefront's cart id, so retried webhooks never create duplicate records.
POST 100 cart payloads to /crm/v3/objects/carts/batch/upsert with idProperty set to external_cart_id and contact associations from the session.
Abandoned Cart Identification
Find carts that have been idle for over 24 hours so a marketing workflow can email the contact. The search endpoint filters by hs_lastmodifieddate and cart status, returning the cart id, contact id, and total for the email template.
POST /crm/v3/objects/carts/search with filterGroups for hs_status equals "OPEN" and hs_lastmodifieddate older than 24h, returning hs_total and associated contact id.
Cart-to-Deal Conversion
When a cart is purchased, update its status, archive it, and create a corresponding deal record. Combine the carts API with the deals API so the conversion is recorded as a sales pipeline event with the cart total and contact intact.
PATCH the cart status to "CHECKOUT_COMPLETED", then POST a deal to /crm/v3/objects/deals/batch/create with the cart total and contact association.
AI Agent Recovery Workflow
An AI agent monitors abandoned carts hourly, generates a personalised recovery message based on cart contents, and triggers the marketing email. Jentic exposes the cart search and contact read operations with typed schemas, so the agent does not need to read HubSpot docs.
Search /crm/v3/objects/carts/search for OPEN carts older than 1 hour, fetch associated contact emails, and trigger the recovery email template with the cart total.
Key Endpoints

Why Jentic?
Three things that make agents converge on Jentic-routed access.
Credential isolation
HubSpot OAuth and private app tokens are encrypted in the Jentic vault. Scoped tokens are injected at execution — raw credentials never enter the agent's context or logs.
Intent-based discovery
Agents search Jentic by intent (e.g. 'sync abandoned carts to hubspot') and Jentic returns the matching cart operation with its typed input schema, so the agent calls the right endpoint without browsing docs.
Time to first call
Direct integration: 2-3 days for OAuth, idempotent upsert, and webhook retry handling. Through Jentic: under 1 hour — search, load schema, execute.

Alternative
Stripe
Stripe checkout sessions handle the cart-to-payment flow without HubSpot CRM linkage.
Choose Stripe when the storefront does not need cart data inside HubSpot CRM and only requires payment capture.
FAQs
Specific to using Carts API through Jentic.
What authentication does the HubSpot Carts API use?
The Carts API supports OAuth 2.0 and HubSpot private app tokens. Through Jentic, tokens live in the encrypted vault and a scoped token is injected per request so raw secrets never enter the agent context.
Can I associate line items with a cart through the HubSpot Carts API?
Yes — pass an associations array of line item ids on cart create, or use the CRM Associations API afterwards. The GET /crm/v3/objects/carts/{cartId} endpoint returns associated line items when you set the associations query parameter.
What are the rate limits for the HubSpot Carts API?
It uses HubSpot's standard CRM v3 limits — 100 requests per 10 seconds for OAuth apps and 110 per 10 seconds for private apps on Pro and Enterprise. Use /crm/v3/objects/carts/batch/upsert (up to 100 carts per call) for bulk storefront sync.
How do I upsert carts through Jentic?
Run the Jentic search "upsert hubspot cart" to find POST /crm/v3/objects/carts/batch/upsert, load the schema, and execute with idProperty set to your storefront's external cart id. Jentic handles auth and returns per-record results.
Is the HubSpot Carts API free?
The Carts API is part of HubSpot Commerce. Access is included in plans that have Commerce Hub or the Commerce features bundled. There is no per-call HubSpot fee on top of the tier subscription.
Can I search carts by total amount?
Yes. POST /crm/v3/objects/carts/search with a filterGroup on the hs_total property using GTE, LTE, or BETWEEN operators. Combine with hs_status to find, for example, abandoned carts above a recovery threshold.
