## Response `200`

A page of the audience's contacts.

- AudienceMemberList
  - `data` AudienceMember[], required: Page of audience members, each a contact paired with the time it joined the audience.
    - `contact` Contact, required
      - `id` string, required
      - `email` string, email, nullable, required: The contact's email address, in its stored form, trimmed and lowercased before uniqueness is checked. Unique within the workspace. `null` when the contact has no email address.
      - `phone_number` string, nullable, required: The contact's phone number in normalized international form: a leading `+` and four to 15 digits. We normalize formatting but do not verify the number against numbering-plan metadata. The number is unique within the workspace. Because carriers recycle disconnected numbers, use `external_id` as the durable key for your own records. `null` when the contact has no phone number.
      - `first_name` string, nullable: The contact's first name. Available in broadcast templates as `bird.contact.first_name`.
      - `last_name` string, nullable: The contact's last name. Available in broadcast templates as `bird.contact.last_name`.
      - `external_id` string, nullable: Your own identifier for this contact, such as a user ID in your system. Unique within the workspace when set.
      - `data` object: Custom property values for this contact, available in broadcast templates as `bird.contact.<key>`. Each key is a property created via the contact properties API, and each value is a string, number, boolean, or RFC 3339 datetime matching the property's declared type (strings up to `500` characters). Total size is capped at 2 KB serialized. Values stored under a property that was later archived remain readable here.
      - `audiences` AudienceRef[]: The audiences this contact belongs to, most-recently-joined first. Only present when listing contacts; omitted from every other contact operation.
        - `id` string, required
        - `name` string, required: The audience's display name.
      - `created_at` string, date-time, required
      - `updated_at` string, date-time, required
    - `joined_at` string, date-time, required: When this contact joined the audience. Members are listed in join order, most recent first.
    - `audiences` AudienceRef[]: The audiences this contact belongs to, including the one being listed, most-recently-joined first.
      - `id` string, required
      - `name` string, required: The audience's display name.
  - `next_cursor` string, nullable, required: Cursor for the next page. Pass back as `starting_after` to advance forward. `null` when no next page exists.
  - `prev_cursor` string, nullable, required: Cursor for the previous page. Pass back as `ending_before` to step backward. `null` when no previous page exists.
  - `refresh_cursor` string, nullable, required: Refresh anchor, the first row of this response. Pass back as `ending_before` to fetch what precedes it in the current sort order. On a newest-first sort those are the items that have appeared since; on any other sort they are the items that sort earlier, so refreshing such a list means re-fetching it instead. Non-`null` whenever `data` is non-empty; `null` only on an empty page. Distinct from `prev_cursor`.
