Scenario: On a discovery call with The Legend of Sleepy Challah, the bakery says that they need to make sure contact records in HubSpot match the contact records in Salesforce. Which direction does data need to sync to make this update possible?

In the HubSpot Data Integration certification, a bidirectional sync is the correct choice because the goal is to ensure that contact records in both HubSpot and Salesforce consistently "match" one another, regardless of where an update occurs. A bidirectional sync establishes a two-way flow of information where changes made to a record in Salesforce are automatically pushed to HubSpot, and vice-versa, maintaining data parity across the entire tech stack. This ensures that sales and marketing teams are always viewing the same real-time information, preventing the data silos and discrepancies that typically arise from a one-directional sync, which only allows one system to act as the source of truth while the other remains a passive recipient.
