You can add your Hubspot calendar to a Vidyard player as an event by following these steps:
1. Go to the Sales section of Hubspot.
2. Press Sales Tools.
3. Finally Meetings.
After going to the meetings sections, you will be able to access your HubSpot embed code. Copy this and paste the code into a Vidyard Event - the post-roll area is most likely the ideal spot. You can refer to this link for more details on adding embed codes to events.
