Contacts
Understand the customer record used by audiences and flows.
A contact represents a customer, identified primarily by phone number. Standard fields and custom attributes provide the data your flows and audience rules use.
For an appointment reminder, a contact might have a name, phone number, and an appointment date stored in a custom attribute. Creating the record does not contact that person.
Imports match existing records by primary phone number and can update them. Review updates before importing.
Next: create a contact or import contacts.
