# Contact Sync Logic

### Contact Sync Logic

When syncing Popl leads to your HubSpot account, the integration will first perform a read operation to see if the contact already exists. This search (query) uses the contact's **"email"** as a primary key to match any existing contact already in your HubSpot. Based on the search, two flows can be taken:

**Create New Contact if No Contact Found:**

If no contact is found from this initial email search, then the integration will proceed to create a new contact. Contact ownership and any custom mappings will be applied based on the configuration settings described above. 

**Update Existing Contact If an Existing Contact is Found:**

If a contact is found with the Popl lead's specific email, then the integration will proceed to update that Contact accordingly instead of creating a new, duplicate Contact. Contact ownership and any custom mappings will be applied based on the configuration settings described above.
