Insert HTML into HubSpot Site <head> Using API

I am developing an app in HubSpot. Once a HubSpot merchant add our app to their site, I want to insert some HTML code, including script tags, into the head section across their entire website. How can I achieve this using the HubSpot API?

Hello,

At this time, HubSpot’s APIs don’t provide a way to programmatically update the Site header HTML (the <head> section).

To make sure you get the right outcome, it’s helpful to clarify a few things:

  • Is your site fully hosted on HubSpot CMS, or are you embedding HubSpot forms/tracking into an external site?
  • Do you need the code across all pages or just certain HubSpot landing pages?
  • What type of code are you looking to add (analytics tracking, chatbot, verification tag, etc.)?

Let me know if this helps, or if you have any other questions!
