There are various actions and events that trigger a sync between HubSpot and Salesforce. HubSpot also checks for new information that needs to be updated across your HubSpot and Salesforce accounts every 15 minutes, and a sync is triggered as needed.
Please note: if you update the value in a mapped Salesforce field that is included in the formula, that update will trigger a sync. However, updates to a Salesforce formula field will not trigger a sync.
If a HubSpot contact meets the sync criteria, check the Salesforce Sync card in their contact record for errors.
In your HubSpot account, navigate to Contacts > Contacts.
Click the name of the contact.
The Salesforce Sync card will display any error(s) preventing the contact from syncing to Salesforce. Click View error detail for more information on what the error is and how to resolve it. Learn more about common Salesforce integration sync errors.
