Once the charges are returned, the second Stripe node gets extra customer information.\n3. Once the customer information is returned, `Merge data` node will merge the customer information with the charges so that the next node `Aggregate totals` can calculate the total amount charged per contact.\n4. Once we have the total amount charged per contact, the `Create or update customer` node will create a new HubSpot property to store the total amount charged.
