Hey sking ,
We do have webhooks and integrations planned on our roadmap for Q2 this year, however, development of our redesigned and improved editor took a little longer than articipated, so the integrations will be moved to the upcoming two months. Hubspot would be a great addition to this as well. So we'll work on it soon!
Can you let us know in what way you would like to use Hubspot with Buttonizer? Then I'll be able to discuss it with my colleagues 🙂
Hope to hear from you soon!
