Hey @JamesClarke

Are you referring to the API documentation from HubSpot? If so, you can find it here: 2026-03 API reference - HubSpot docs

If this doesn’t answer your question, please let me know. The more details, and information you can provide, the better the Community can assist.

Thank you

Sharon

Hi Sharon,

Thanks for the link, I had come across this repository but couldn’t find anything relating to the Knowledge Base. This is definitely where it would live if it had been created and the thread I linked prevously suggests that perhaps it hasn’t.

Unless I’ve oerlooked something? Is there somewhere specific that you think relates to the Knowledge Base API documents here?

Many thanks,

James

Hey @JamesClarke

I can’t see anything related to the Knowledge base in the API documents- However, is not clear to me what is your goal. Could you please provide more information on what you would like to accomplish? :slightly_smiling_face:

Thank you

Hi Sharon,

The knowledge base sits on a sub-domain which is not suitable for our website and so would like to create our own knowledge base page driven by use of the Knowledge Base API.

From what I can gather, this exists but I can’t find any documentation.

Thanks,

James

Hi @JamesClarke

I have been in contact with the team and they confirmed the Site Search endpoint doesn’t yet document the ability to search Knowledge Base articles, but technically it’s currently capable of providing Knowledge Base search results.
There is no article-specific endpoint. The Content Search API is the only way to pull the Knowledge Base article search results. So you can query kb articles but cannot interact with them it would seem.

I hope this helps.

Hi Sharon,

Many thanks for looking into this. Is it something that’s on the road map to buld out?

James, could you create an iframe to view the subdomain to enable all of the search and native functionality of the tool without redirecting?

Hi,

Thanks for this suggestion, it is what we’ve been trying to do but there is some issues with this whereby the autocomplete search results are nn-responsive.

Any ideas would be appreciated.

Thanks,

To update this ticket, we ended up doing some messing around with iframes as we didn’t want to direct the user away from our website to use the knowledge base. This is how it now looks. Help Clothes2order.com

If more time was spent on it, it could look a bit better.

Hi, @michelkamp and @JamesClarke.

Unfortunately, there are no public APIs for the knowledge base tool at this time. Knowledge base articles can currently only be created or modified in the HubSpot UI.

We have heard this request come up before. While I don’t know of any plans to release a Knowledge Base API in the near future, I will pass this feedback to the team and share any relevant details.
In the meantime, the best way to request this feature is to upvote and comment on this Ideas Forum post with your use cases. I’ve already upvoted it myself.

It would be so awesome to be able to pull down the knowledge base content. Please can you let us know if you develop this :slightly_smiling_face:

15

Thanks for posting, @FriendlyManager.

I agree!

If you haven’t already, please be sure to upvote and comment on the official feature request.

Hi Its been over a year since this discussion waw broached. I know Zendesk has an API for knowedge base articles - at a former company we got oour help articles out of their kb and into our application via API. Any update on this for HubSpot?

This is marked as not currently planned but this can change based on feedback and upvotes. You can also see more info with the update from the Product Team.

Thank you

Thanks very much T for the reply and link- upvoted. The original request is 2.5 years old, and with at least one competitors having APIs to docs - lets hope this gets prioritized. Inertia seems absolute at times, but suddenly we can decide

19

Automation is now key to many organzations. If HS is going to be the source of truth, these API’s become more important. CMS and KB needs to be integrated with development, for product updates to our clients.

Also trying to bump this conversation again. While being able to manage the KB docs via API would be great, it is more important that we can access and render them in our native applications.
