Labels and attributes belong to the connected phone number. Use them to group contacts and to store extra fields, such as a plan name or a city.

​
Labels

Open Contacts, then Labels.
  • Create a label and assign it to contacts.
  • Import or export the label list.
  • Filter broadcasts and automation conditions by label.
A contact can have more than one label. Deleting a label removes it from contacts. It does not delete the contacts.

​
Attributes

Open Contacts, then Attributes. Attributes are the custom fields on a contact, separate from first name, last name, and phone number. Define the attribute once, then set a value on each contact. You can import and export attribute definitions the same way as labels.

​
Where they show up

  • Broadcast contact selection can filter the audience with labels and attributes.
  • Automations can check a label or an attribute, then set either one as a step.
  • The Developer API lists and updates both catalogs with GET /v1/labels and GET /v1/attributes. Contact payloads reference those ids.
