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 | sh

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 instance

Jentic 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.

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.

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

11 endpoints — the hubspot carts api manages cart records inside hubspot commerce, representing in-progress purchases that can be associated with contacts, line items, and deals.

Why Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Your HubSpot OAuth token or private app token is stored once, encrypted, by your own Jentic One instance and injected at execution time. It never enters the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'sync an abandoned cart to HubSpot' or 'read cart records', and Jentic returns the matching cart operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

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.

Can I limit what my agent is allowed to do with the HubSpot Carts API?

Yes. Because you run Jentic One yourself, your own rules decide which HubSpot Carts operations and credentials your agent may use. HubSpot gates this API with per-object OAuth scopes, so you can grant read-only cart access, letting the agent search carts and retrieve a single cart while leaving batch create, batch upsert, batch update, and archive out of the allowed set. You control exactly which endpoints the agent can call and which HubSpot token it runs with.
