Contact Identifier

Identifiers refer to distinct values representing contacts, such as an email address, phone number, or external ID. When adding or updating contacts, these identifiers are used for identification purposes and will prevent duplicates when adding more contacts in the future.

When starting to use contacts, it is essential to determine which identifier you wish to support.
This will depend on your use case:

email: used when primarily sending emails to contacts. This is the identifier by default.
phone: used for SMS and voice communication as the primary means of interacting with contacts
external ID: this is a unique identifier assigned to an individual. Typically, this value represents a person in your backend systems, such as a unique username, user ID, employee ID, or contract number.
Naxai ID: this unique identifier is created by Naxai to identify the contact
