# People Sync Logic

#### People Sync Logic <a href="#contact-sync-logic" id="contact-sync-logic"></a>

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

**Create New Record if No Record Found:**

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

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

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