View OpenAPI Document

The HubSpot CRM Line Items API manages the priced rows that compose deals, quotes, invoices, and subscriptions in HubSpot Commerce. It exposes single-record CRUD, batch read, batch create, batch update, batch upsert, batch archive, and search for line item records with full property and association support. Use it to build a quote out of products, attach line items to a deal during pipeline progression, or sync line-level pricing data between HubSpot and an external billing or e-commerce system.

Use Cases

Patterns agents use Line Items API for, with concrete tasks.

★ Build a Quote with Multiple Products

When a sales rep or agent assembles a quote in HubSpot, each product on the quote is a separate line item record. Using the batch create endpoint, an integration can write all the line items in a single call and link them to the parent quote via the associations array. This pattern keeps the quote consistent with the source product catalogue and avoids per-row API calls.

POST /crm/v3/objects/line_items/batch/create with up to 100 line item records, each carrying an associations entry for the parent quote, and confirm the response status array reports zero errors.

Mirror Stripe Subscription Items into HubSpot

Reflect the line-item composition of a Stripe subscription on the corresponding HubSpot subscription record so the CRM shows the same priced rows the customer is actually being billed for. Batch upsert keyed by an external Stripe item ID handles both create and update in one call, which is the typical pattern for a sync that runs every few minutes off Stripe webhooks.

POST /crm/v3/objects/line_items/batch/upsert with line item records keyed by stripe_item_id, each linked via associations to the HubSpot subscription record.

Agent-Driven Quote Adjustment

An AI agent that drafts or revises quotes can search for the existing line items on a deal, recompute pricing or quantities, and update the records via batch update. Through Jentic, the agent finds the relevant line item operations by intent and chains search and update calls without browsing HubSpot's REST docs.

Search line items via POST /crm/v3/objects/line_items/search filtered by associated deal ID, then POST /crm/v3/objects/line_items/batch/update with new price values reflecting the agent's revised quote.

Why though Jentic?

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

Credential isolation

HubSpot OAuth and Private App tokens are stored encrypted in the Jentic vault. Agents receive scoped access references, never raw tokens.

Intent-based discovery

Agents search by intent (e.g., 'add line items to a HubSpot quote') and Jentic returns the matching operations with input schemas including the associations array shape.

Time to first call

Direct integration: 1-2 days for OAuth, batch sync, and association handling. Through Jentic: under 30 minutes.

FAQs

Specific to using Line Items API through Jentic.

What authentication does the HubSpot Line Items API use?

OAuth 2.0 Bearer tokens or HubSpot Private App tokens in the Authorization header. Jentic stores the token encrypted in the vault and provides a scoped reference to the agent so the raw token never enters the prompt.

Can I create a line item and link it to a deal in one call?

Yes. POST /crm/v3/objects/line_items accepts an associations array on the request body so the line item is created and linked to a deal, quote, invoice, or subscription in a single call.

What are the rate limits for the HubSpot Line Items API?

Standard HubSpot quotas apply: 100 requests per 10 seconds for OAuth apps and 110 for Private Apps, plus daily caps that vary by Hub tier. Batch endpoints accept up to 100 records per call and count as one request, which is the recommended pattern for high-volume sync jobs.

How do I add multiple line items to a quote through Jentic?

Run pip install jentic, call client.search('add line items to a HubSpot quote'), client.load to get the schema for POST /crm/v3/objects/line_items/batch/create, and client.execute with the line item array — each entry includes properties and an associations array pointing at the parent quote.

Can I search line items by product ID?

Yes. POST /crm/v3/objects/line_items/search accepts filterGroups, including a filter on hs_product_id, so you can find every line item that references a particular product across deals and quotes.

How do I keep line items in sync with an external billing system?

POST /crm/v3/objects/line_items/batch/upsert keyed by a unique external identifier property (such as stripe_item_id) handles both create and update in one call, which is the typical sync pattern when mirroring Stripe or another billing system into HubSpot.
