There's a new version of the HubSpot API

As of November 30, 2022, HubSpot API Keys are being deprecated and are no longer supported. Continued use of HubSpot API Keys is a security risk to your account and data. Your API Keys could be deactivated at any time after Nov. 30th, and we recommend that you migrate to Private Apps as soon as possible so you do not lose business-critical functionality.

Developer Preview Overview

What is a developer preview?

We want to make it even easier to discover and experiment with the next generation of HubSpot product releases. 

Whenever you see the “preview” tag anywhere on the developer site, you are encountering a pre-release feature, API, or endpoint. Items with a "preview" tag should be considered a non-stable release that will be subject to bugs and breaking changes while under development. Please take this into account as you build against a release.

New features and bug fixes will be released based on developer feedback throughout the preview period.

To communicate feedback during this developer preview you can:
  • Watch for updates in the HubSpot developer community within the announcements category
  • Keep up to date on the latest releases by subscribing to our changelog
