Announcement: New apps will only work with OAuth 2.0



Hi Everyone,

Starting tomorrow, any new apps created in HubSpot will only allow users to authenticate using OAuth 2.0, meaning that you’ll need to use the new methods for initiating the OAuth connection and getting the initial access and refresh tokens

This will only affect newly created apps, and will not affect any existing apps. Any existing app currently using our previous OAuth system will continue to work with that system.
