For Agents
Create, update, and organise HubSpot blog tags in batches and across multi-language variation groups. Useful for agents that publish or curate blog taxonomy.
Get started with Tags in minutes using your preferred integration method.
# Add to your MCP client config (Claude Desktop, Cursor, Windsurf)
{
"jentic": {
"url": "https://api.jentic.com/mcp",
"auth": "oauth"
}
}
# Then ask your agent:
"create a HubSpot blog tag"
# → Jentic returns the GET /events tool with parameter schema, agent executes.What an agent can do with Tags API.
Create individual or batched blog tags with name and slug values
Update existing blog tag records and rename tags across the CMS
Archive blog tags singly or in batches without affecting tagged posts
Attach blog tags to multi-language variation groups for translated content
Set a new primary language for a tag's translation group
GET STARTED
Use for: Create a new blog tag for a HubSpot blog post, Update the name of an existing blog tag, Archive multiple unused blog tags in one batch call, List all blog tags currently published on the HubSpot CMS
Not supported: Does not handle blog post content, page rendering, or site search indexing — use for HubSpot blog tag taxonomy management only.
The HubSpot Tags API manages blog tags within the HubSpot CMS, including creation, batch updates, archival, and multi-language tag groupings. It supports attaching tags to language variation groups, designating primary languages, and reading tag metadata for use across HubSpot blog content. Tags are scoped to the HubSpot blog system and link blog posts to topical taxonomies for site search and content organisation.
Detach a blog tag from its multi-language group
Retrieve a paginated list of all blog tags or a batch by ID
Patterns agents use Tags API for, with concrete tasks.
★ Bulk Tag Cleanup
Audit and consolidate a HubSpot blog's tag taxonomy by archiving unused tags and merging duplicates. The Tags API supports batch archive and batch update operations so an agent can process dozens of tag records in a single call without rate-limiting on per-record requests. Suitable for content teams cleaning up legacy blogs or merging blog properties.
Read the full list of blog tags via GET /cms/v3/blogs/tags, identify tags with zero associated posts, and call POST /cms/v3/blogs/tags/batch/archive with the unused tag IDs.
Multi-Language Blog Tag Localisation
Maintain translated tag variants across a multilingual HubSpot blog. The API exposes endpoints for attaching, detaching, and creating language variations and for setting the primary language of a tag group. This allows an agent to keep tag translations in sync with localised blog posts and reassign primary languages when the source content changes.
Call POST /cms/v3/blogs/tags/multi-language/create-language-variation to create a French variant of an English tag, then POST /cms/v3/blogs/tags/multi-language/attach-to-lang-group to link it to the source group.
Programmatic Tag Provisioning
Provision a fixed taxonomy of blog tags as part of a HubSpot blog rollout or migration. The batch create endpoint accepts up to 100 tag definitions per call, so a migration script or agent can import a taxonomy from another CMS in seconds rather than creating each tag individually through the UI.
Read a CSV of 50 tag names, build a batch payload, and POST /cms/v3/blogs/tags/batch/create to provision them in one request.
Agent-Driven Editorial Workflow
Use Jentic to give an editorial AI agent the ability to maintain HubSpot blog tags as part of a wider content workflow. The agent searches Jentic for the relevant tag operation, loads the input schema, and executes the call without browsing HubSpot's developer docs. Credential isolation keeps the HubSpot private app token out of the agent's reasoning context.
Use Jentic search query 'create a HubSpot blog tag', load the schema for POST /cms/v3/blogs/tags, and execute the call with the tag name from the editorial brief.
14 endpoints — the hubspot tags api manages blog tags within the hubspot cms, including creation, batch updates, archival, and multi-language tag groupings.

Three things that make agents converge on Jentic-routed access.
Credential isolation
HubSpot OAuth tokens and private app tokens for the Tags API are stored encrypted in the Jentic vault. Agents receive scoped execution tokens; the raw HubSpot credential never enters the agent's context.
Intent-based discovery
Agents search Jentic with intents such as 'create a blog tag' or 'archive blog tags' and Jentic returns the matching Tags API operation with its input schema, so the agent calls the right endpoint without reading HubSpot docs.
Time to first call
Direct HubSpot integration with auth, error handling, and batch logic typically takes 1-2 days. Through Jentic: under 30 minutes — search, load, execute.
Alternatives and complements available in the Jentic catalogue.
HubSpot CMS Blog Posts
Manage the blog posts that the tags are applied to.
Choose CMS-posts when the agent needs to assign tags to specific posts or fetch posts filtered by tag, rather than managing the tag taxonomy itself.
HubSpot CMS Blog Authors
Manage blog author records that pair with tagged posts.
Use CMS-authors when populating author metadata alongside tag taxonomy during a blog migration.
HubSpot CMS Blog Settings
Configure blog-level settings that govern tag behaviour and language defaults.
Pick CMS-blogSettings when the agent needs to set default languages or blog-wide options before provisioning tags.
Specific to using Tags API through Jentic.
What authentication does the HubSpot Tags API use?
The Tags API accepts HubSpot OAuth 2.0 access tokens (legacy authorization code flow) or a private app token sent in the `private-app-legacy` header. Through Jentic, the token is stored encrypted in the vault and never enters the agent's prompt context.
Can I update many blog tags in a single request with the Tags API?
Yes. POST /cms/v3/blogs/tags/batch/update accepts a batch of tag updates in one call, and there are matching batch endpoints for create, read, and archive under /cms/v3/blogs/tags/batch/.
What are the rate limits for the HubSpot Tags API?
HubSpot enforces account-wide CMS API limits — typically 100 requests per 10 seconds for OAuth apps and 250,000 daily on most paid tiers. Use the batch endpoints to reduce request volume on tag-heavy operations.
How do I create a new blog tag through Jentic?
Search Jentic with the query `create a HubSpot blog tag`, load the schema for POST /cms/v3/blogs/tags, and execute with the tag name and slug. Install the SDK with `pip install jentic` and authenticate using your `JENTIC_AGENT_API_KEY`.
Does the Tags API support multilingual blog content?
Yes. The endpoints under /cms/v3/blogs/tags/multi-language/ let you attach tags to language groups, create language variations, set a primary language, and detach tags from a group, so a single tag concept can have synchronised translations.
/cms/v3/blogs/tags/batch/archive
