Marketing API Beta

HubSpot Employee

What is the Marketing API v3 beta?


To date, one of the most consistent points of feedback that we’ve heard from the external development community is that our Marketing APIs are difficult to use because they are not standardized. Our product team is hard at work building a new set of Marketing APIs based on a more modern and consistent framework. As part of this Beta, you will have the opportunity to test this new functionality and provide feedback directly to our product team.
