List Contact Devices

List every device a contact has registered, including revoked and expired ones.

Use this to answer support questions — "why didn't this customer get the notification?" — by checking device status, permission state, and whether the Arsel SDK is embedded.

Field	Type	Description
id	string	Device ID (UUIDv7)
installation_id	string	The natural key. Correlate on this across every push route.
platform	string	android, ios, web
vendor	string	fcm, apns, web_push
status	string	ACTIVE, EXPIRED, REVOKED, FAILED
revoke_reason	string | null	user_opt_out, contact_opt_out, dead_token, or admin
device_token_masked	string | null	First and last few characters only
enablement_status	string | null	OS permission last reported by the device
sdk_enabled	boolean	Whether the Arsel SDK is embedded on this device
sdk_version	string | null	e.g. android/1.2.0
last_used_at	string | null	Last time Arsel sent to this device
last_seen_at	string | null	Last time the device checked in

The raw device token is never returned

device_token_masked shows only the first and last few characters. The full token is a sendable credential — anyone holding it and your Firebase project could push to that device — so Arsel never returns it, not even to the account that supplied it. Correlate on installation_id instead.

Reading revoke_reason

Value	Meaning	Reversible?
user_opt_out	The user opted out in your app	No — durable
contact_opt_out	Revoked via Unregister Device	No — durable
dead_token	The transport rejected the token permanently (uninstall, ~270 days inactive, or the token belongs to a different Firebase sender)	Yes — a successful re-register clears it
admin	Revoked by Arsel staff	—
