Install Jentic One Beta

Connect the Lists to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Lists, 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.

Capabilities

For Agents

Create and manage HubSpot CRM lists, edit filter definitions, add and remove records from lists, and organise lists into folders.

Use for: I need to create a static list of high-value contacts for a campaign, I want to add 500 contacts to an existing HubSpot list, Search for all lists scoped to the deals object, Find a list by its name without knowing its ID

Not supported: Does not handle marketing email sending, workflow execution, or contact property creation - use for HubSpot CRM list and membership management only.

Use Cases

Patterns agents use Lists API for, with concrete tasks.

★ Programmatic Audience Curation for Campaigns

Build a static list of contacts for a marketing send or workflow trigger by creating the list and then adding members in bulk. The Lists API exposes both a one-shot add endpoint and a combined add-and-remove endpoint, which is the right shape for incremental curation as new records qualify or fall out of scope. Lists of tens of thousands of members are routinely managed this way and feed directly into HubSpot Workflows.

POST /crm/v3/lists with a static list payload, capture the listId, then PUT /crm/v3/lists/{listId}/memberships/add with the contact IDs to add, in batches of up to 100.

Migrate from Legacy List IDs

Older HubSpot integrations stored v1 list IDs that are not interchangeable with the modern v3 list IDs returned by current endpoints. The Lists API offers single and batch ID translation endpoints so a migration script can rewrite stored references in bulk without manual lookup. Translating thousands of legacy IDs typically completes in a single batch request.

POST /crm/v3/lists/idmapping with an array of legacy list IDs and persist the returned modern IDs against each downstream record in the migration script.

Agent-Driven Active List Tuning

An AI agent that maintains marketing audiences can search for an active list by name, inspect its current filter definition, and update the filter when the underlying segmentation logic changes. Through Jentic, the agent finds the search and update operations by intent and chains them, which is useful for marketing-ops copilots that respond to brief updates.

Find the list with GET /crm/v3/lists/object-type-id/{objectTypeId}/name/{listName}, then PUT /crm/v3/lists/{listId}/update-list-filters with the revised filter branch.

Key Endpoints

25 endpoints — the hubspot crm lists api manages static and active (filter-defined) lists for any crm object - contacts, companies, deals, custom objects.

Why Jentic?

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

Credential isolation

Your HubSpot 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 'add records to a HubSpot list' or 'search CRM lists', and Jentic returns the matching membership operation with its input schema, including listId and the member id array shape, so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using Lists API through Jentic.

What authentication does the HubSpot Lists 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 the agent with a scoped reference, so the raw token never enters the prompt.

Can I create a list that auto-updates as records change?

Yes. Create the list with a filter definition (an active list) and the membership is recomputed automatically as records change in the portal. PUT /crm/v3/lists/{listId}/update-list-filters can revise that definition later.

What are the rate limits for the HubSpot Lists API?

Standard HubSpot quotas apply: 100 requests per 10 seconds for OAuth apps and 110 for Private Apps, with daily caps that vary by Hub tier. Membership add and remove calls accept up to 100 record IDs per request, which is the recommended pattern for bulk curation.

How do I add contacts to an existing list through Jentic?

Run pip install jentic, call client.search('add records to a HubSpot list'), client.load to get the schema for PUT /crm/v3/lists/{listId}/memberships/add, and client.execute with the listId and an array of contact IDs.

Can I look up a list by name instead of ID?

Yes. GET /crm/v3/lists/object-type-id/{objectTypeId}/name/{listName} returns the list metadata for a given name and object type, which avoids storing list IDs in downstream systems.

How do I migrate from legacy v1 list IDs to v3 IDs?

POST /crm/v3/lists/idmapping accepts an array of legacy list IDs and returns the corresponding modern IDs in a single call. This is the recommended pattern for migration scripts that have legacy IDs persisted against downstream records.

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

Yes. Because you run Jentic One yourself, your own rules decide which operations and credentials the agent may use. Since this API carries the list ID in the URL path (/crm/v3/lists/{listId}/...), you can pin the agent to a single list and allow only the operations you intend, such as reading that list with GET /crm/v3/lists/{listId} and adding members with PUT /crm/v3/lists/{listId}/memberships/add. A destructive operation like DELETE /crm/v3/lists/{listId} stays out of reach unless you explicitly grant it.
