Customer identities and merged customers
ACustomer object represents one customer identity. This identity is tied to a browser cookie, so the same person may have separate Customer objects when they use different browsers or devices.
Text can connect identities that belong to the same person and return their combined data as a merged customer. The original Customer objects remain separate and continue receiving updates.
Use Get customer to retrieve one identity or Get merged customer to retrieve combined data.
