For Agents
Manage HubSpot blog author records and their multi-language variants, so an agent can attach the correct byline to a blog post before publishing.
Use for: Create a HubSpot blog author named Jane Doe, Find the author profile linked to a translated blog post, List all blog authors that have been archived, Retrieve an author by their HubSpot object ID
Not supported: Does not write blog posts, manage tags, or upload avatar images - use for managing HubSpot blog author records and their language groupings only.
The HubSpot CMS Blog Authors API manages the author records that appear as bylines on HubSpot-hosted blog posts. It exposes single and batch endpoints for creating, reading, updating, and archiving authors, plus a multi-language group so the same author can be linked across translated blog content. Use it to keep author profiles, photos, and bios in sync with an external system of record such as a headless CMS or HR directory.
Install Jentic One Beta
Connect the Authors to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Authors, 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-cms-authors" | 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-cms-authors" | 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 Authors API.
Create blog author profiles individually or in batches with name, bio, and avatar fields
Look up an author by object ID before assigning them as a blog post byline
Archive authors that are no longer active without deleting their historical posts
Attach an author to a multi-language group so translated posts share one byline identity
Update author metadata for every language variant in a single batch call
Detach a translated author from its language group when a profile is split
Use Cases
Patterns agents use Authors API for, with concrete tasks.
★ Sync Author Directory From HRIS
Companies that publish blog content from named employees often want HubSpot author records to mirror their HR directory. Using the batch create and update endpoints, a nightly job can mint new authors when employees join and archive them when they leave. The multi-language endpoints keep one author identity across translated posts so the byline stays consistent.
Read 50 employee records from the HRIS, transform them into the HubSpot author schema, and POST them in one call to /cms/v3/blogs/authors/batch/create.
Multi-Language Byline Management
Brands publishing in multiple languages need each translated post to credit the same human author rather than a duplicate per locale. The multi-language endpoints attach an author to a language group, set the primary language, and update bios across variants in one call. This prevents fragmented author pages and improves SEO for branded content.
Group three author records (en, es, de) under one language group via /cms/v3/blogs/authors/multi-language/attach-to-lang-group and mark the English variant as primary.
Author Profile Cleanup
Editorial teams accumulate stale author records over time. The list endpoint paired with batch archive lets an agent identify authors with no recent posts and retire them in one operation, leaving past blog posts and their original byline intact.
List all authors via /cms/v3/blogs/authors, filter to those whose ID is not referenced in the last 100 blog posts, and archive them with /cms/v3/blogs/authors/batch/archive.
Agent-Driven Blog Publishing
An AI publishing agent that drafts a blog post must attach a real author. Through Jentic, the agent searches for the author lookup operation, picks the correct profile by name, and passes the returned ID to the CMS Posts API. Jentic abstracts the OAuth handshake and returns the operation schema directly to the agent.
Use Jentic to search 'find hubspot blog author by name', load the schema, execute it with name='Jane Doe', and pass the returned objectId into the next blog post creation call.

What agents get from Jentic-routed access to this vendor.
Setup
Wiring HubSpot Authors by hand means setting up the OAuth authorization-code flow or a private app token, targeting api.hubapi.com, and coding the batch create, read, and update calls plus paging yourself. Through Jentic you install once, import Authors from the API Directory, store the token once, and your agent calls it.
Permission scoping
Most Authors writes travel in the request body through batch endpoints, so scope your agent to the operations it needs, such as listing authors or reading one by id. You choose the operations it may call, so batch archive is only available if you include it.
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 'create a HubSpot blog author' or 'attach an author to a language group', and Jentic returns the matching Authors operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs
Specific to using Authors API through Jentic.
What authentication does the HubSpot Blog Authors API use?
It accepts HubSpot OAuth 2.0 access tokens or a Private App token in the Authorization header, with the content scope. Jentic stores those credentials in its vault so the agent only receives a scoped execution token at call time.
Can I bulk-create blog authors with the HubSpot Authors API?
Yes. POST /cms/v3/blogs/authors/batch/create accepts an array of author objects in one request, returning created records with their HubSpot object IDs. Pair it with /cms/v3/blogs/authors/batch/update for revisions.
What are the rate limits for the HubSpot Authors API?
Standard HubSpot public API limits apply: 100 requests per 10 seconds for OAuth apps and 110 requests per 10 seconds for Private Apps on Pro and Enterprise. Batch endpoints count as one request even when they update many authors.
How do I attach an author to a translated blog post through Jentic?
After pip install jentic, search 'attach hubspot blog author to language group', load the returned schema, and execute it with the author IDs and locale. Jentic resolves OAuth and posts to /cms/v3/blogs/authors/multi-language/attach-to-lang-group on the agent's behalf.
Does the Authors API let me delete an author permanently?
No. HubSpot only supports archiving via /cms/v3/blogs/authors/batch/archive. Archived authors are hidden from new selections but their byline remains on historical posts.
Can the API upload an author's avatar image?
Not directly - the spec exposes metadata fields like fullName, bio, and avatar (URL) but not file upload. Host the image first via the HubSpot Files API, then pass the URL into the avatar field.
Can I limit what my agent is allowed to do with the HubSpot Blog Authors API?
Yes. Because you run Jentic One yourself, you decide which HubSpot Authors operations your agent may call, so you can grant read-only access such as listing authors or retrieving one by object ID while withholding the batch create, update, and archive endpoints. Most writes travel in the request body through those batch operations, so an agent scoped to only the read operations cannot mint or archive author records. Batch archive is available to the agent only if you explicitly include it, and your stored HubSpot token is injected at execution time rather than exposed to the agent.
