For Agents
Look up the HubSpot users available as record owners and resolve owner IDs, emails, and team memberships before assigning CRM records.
Use for: I need to find the HubSpot owner ID for a sales rep by email, List all active owners on the HubSpot account, Retrieve the team membership for a specific HubSpot owner, Get the primary team for the owner I'm about to assign a deal to
Not supported: Does not create users, manage permissions, or modify team membership - use for read-only owner lookup before record assignment only.
The HubSpot CRM Owners API returns the owners that can be assigned to CRM records (contacts, deals, companies, tickets, and custom objects) via the hubspot_owner_id property. It exposes a list endpoint and a single-owner lookup endpoint, both of which include team membership information when teams are enabled on the account. Agents typically call this API to resolve an owner email or ID before creating or updating a record so the new object lands with the correct sales rep or CSM.
Install Jentic One Beta
Connect the CRM Crm Owners to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the CRM Crm Owners, 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://jentic.com/install.sh?src=apis&api=%2Fapis%2Fhubspot.com%2Fhubspot-crm-owners" | sh2
Step 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fhubspot.com%2Fhubspot-crm-owners" | 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 CRM Crm Owners API.
List all CRM owners on the HubSpot account via GET /crm/v3/owners/
Retrieve a single owner's details and team membership with GET /crm/v3/owners/{ownerId}
Filter the owners list by email to find the right user before assigning a record
Page through large owner directories using the standard after cursor pagination
Identify each owner's primary team to route records by territory or pod
Use Cases
Patterns agents use CRM Crm Owners API for, with concrete tasks.
★ Resolve Owner Before Record Creation
Before creating a contact, deal, or custom object, look up the correct hubspot_owner_id by the rep's email so the record lands in the right rep's queue. The list endpoint accepts an email query parameter, returning the matching owner with their ID, team memberships, and active status. This avoids hard-coding owner IDs that change when reps leave or join.
Call GET /crm/v3/owners/?email=jane@example.com, extract the id from the first result, and use it as hubspot_owner_id when creating a new deal.
Owner Directory Sync
Mirror the HubSpot owner directory into an internal user system or routing engine so downstream automations can map records to teams. The list endpoint returns paginated results with team membership, so a nightly job can cache the full directory and detect joiners and leavers. Use the after cursor to walk through accounts with hundreds of users.
Page through GET /crm/v3/owners/ until the paging.next.after cursor is absent, collecting every owner's id, email, and primary team into a local lookup table.
Team-Based Record Routing
Route incoming leads, tickets, or deals to a specific team by first finding owners on that team. Each owner's response includes a teams array marking the primary team, so a routing agent can pick the next owner from the matching team using a round-robin or load-balanced strategy. This keeps territory rules consistent without duplicating team data outside HubSpot.
Fetch GET /crm/v3/owners/ filtered to active owners, group results by primary team, then pick the next owner from the EMEA team to assign a new lead.
Owner Lookup via Jentic for AI Agents
An AI agent creating a HubSpot record needs to set hubspot_owner_id without prompting the user. Through Jentic, the agent searches for the owners lookup operation, executes it with the rep's email, and chains the resulting ID into the next CRM call. The whole flow runs on a single Jentic credential without exposing the HubSpot API key to the model.
Use Jentic to search 'find a HubSpot owner by email', execute GET /crm/v3/owners/ with email=alex@company.com, and pass the returned id to the next create-deal call.
Key Endpoints
2 endpoints — the hubspot crm owners api returns the owners that can be assigned to crm records (contacts, deals, companies, tickets, and custom objects) via the hubspot_owner_id property.

What agents get from Jentic-routed access to this vendor.
Setup
Wiring the HubSpot Owners API by hand means handling its OAuth 2.0 authorization-code flow or a private app token, targeting api.hubapi.com, and coding the owner lookup and pagination yourself. Through Jentic you install once, import HubSpot Owners from the API Directory, store the token once, and your agent calls it.
Permission scoping
This API is read-only and HubSpot gates it with the owners read scope, so you grant only that scope and you choose which operations it may call: you can allow listing owners and fetching one owner by id and nothing that writes, since no write operation exists here to add.
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 'find a HubSpot owner by email' or 'list CRM owners', and Jentic returns the owners operation with its query parameter schema so the agent calls the right endpoint without browsing the reference docs.

FAQs
Specific to using CRM Crm Owners API through Jentic.
What authentication does the HubSpot CRM Owners API use?
The Owners API accepts OAuth 2.0 access tokens with the crm.objects.owners.read scope or HubSpot private app API keys passed in the private-app or private-app-legacy header. Through Jentic the credential lives in your Jentic One instance and is injected at request time, so the API key never enters the agent's context.
Can I look up a HubSpot owner by email with this API?
Yes. GET /crm/v3/owners/ accepts an email query parameter that filters the response to the matching owner. This is the recommended way to resolve hubspot_owner_id from a rep's email rather than hard-coding numeric IDs that can change.
What are the rate limits for the HubSpot CRM Owners API?
Owners calls share HubSpot's account-wide limit - typically 100 requests per 10 seconds for OAuth apps and 190 per 10 seconds for private apps on paid tiers. Cache the owners list for the duration of a sync job rather than calling per record.
How do I get an owner's team through Jentic?
Run jentic.search('get a HubSpot owner with team details'), load the schema for GET /crm/v3/owners/{ownerId}, and execute it with the owner ID. The response includes a teams array marking the primary team, which Jentic returns as structured JSON.
Does the Owners API let me create or update users?
No. This API is read-only for the owner directory. Adding or removing users is done through the HubSpot UI or the Settings APIs - Owners only exposes who is currently available for record assignment.
What is the difference between an owner ID and a user email?
The owner ID is the numeric value HubSpot uses internally for the hubspot_owner_id property on records. Email is the user's login. Always set hubspot_owner_id with the numeric ID returned by GET /crm/v3/owners/, not the email.
Can I limit what my agent is allowed to do with the HubSpot CRM Owners API?
Yes. Because Jentic One is self-hosted, you decide which operations your agent may call, and you can allow just the two read operations this API exposes: listing owners with GET /crm/v3/owners/ and fetching a single owner by ID with GET /crm/v3/owners/{ownerId}. The API is read-only and HubSpot gates it with the owners read scope, so you grant only that scope and no write operation is ever available to the agent. You also control the stored HubSpot token, which is injected at request time and never enters the agent's context.
