Contacts are the basis of all customer data in Airship. Contacts records can store all sorts of data such as contact information and personal details. A contact record can also have any number of transactional records attached to them to represent a contact's timeline of interactions. For example, Table Bookings, WiFi interactions, Feedback, Purchase History and more.
Airship automatically merges contact records together based on unique customer identifiers. These identifiers are email or mobile_number. In other words, if you write a contact to us with an email address or mobile that already exists as part of a contact on Airship, we'll automatically update and/or append the data you send to the pre-existing contact record.
