# List your sandbox sessions

`GET /v1/whatsapp/sandbox/sessions`

Returns all of the authenticated user's non-expired sandbox sessions
(pending + active) plus the sandbox phone number. In practice there
is at most one session per user since the sandbox is one-phone-per-user;
the array shape is preserved for forward compatibility.

## Response `200`

    - `id` string, required — Session id. Use this to revoke via DELETE.
    - `phoneE164` string, required — Digits-only E.164 form (no +, spaces, or dashes).
