Poll (Unified)

Poll (Unified)

POST /?endpoint=poll

The preferred endpoint for the Android service loop. A single POST replaces the need for separate calls to heartbeat, pending_messages, get_config, and command fetching. Call this every few seconds from the background service.

Recommended: Use poll as your primary background-service loop. It replaces pending_messages, heartbeat, get_config, and command fetching in a single request.

Request Body (all fields optional)

Field	Type	Description
service_active	boolean	`true` if the background service is running.
sms_count	integer	Total SMS messages sent since last reset.
fail_count	integer	Total failed messages since last reset.
whatsapp_enabled	boolean	`true` if WhatsApp is connected on the device.
is_default_sms	boolean	`true` if this app is the default SMS handler.
fcm_token	string	Updated FCM token (send only when it changes).
ack_ids	integer[]	Array of command IDs to acknowledge and delete before receiving new ones.
sms_limit	integer	Max SMS items to return in this response (1-10, default 1).
wa_limit	integer	Max WhatsApp items to return in this response (1-10, default 10).

}

Response Fields

Field	Type	Description
config	object	Key/value device configuration set from the web panel.
commands	array	Pending commands for this device. ACK them via `ack_ids` on the next poll.
sms	array	Claimed SMS messages ready to send (same schema as `pending_messages`).
whatsapp	array	Claimed WhatsApp messages ready to send.
ai_config	object\|null	WhatsApp Gemini AI configuration (system prompt, keys, model settings). `null` if not configured.

Command Payload

command	Description
restart_service	App should restart its background SMS service.
set_default_sms	Prompt user to set app as default SMS handler.
update_config	Re-fetch config (payload contains changed keys).

On every poll, the server automatically resets messages stuck in processing for more than 5 minutes back to pending. This handles app crashes without manual intervention.

Typical Service Loop (Android)

Kotlin (pseudocode)

while (serviceRunning) {
    val resp = api.poll(
        service_active = true,
        sms_count      = smsSentTotal,
        ack_ids        = pendingAckIds
    )
    pendingAckIds.clear()

    for (cmd in resp.commands)  handleCommand(cmd)
    for (sms in resp.sms)       sendSms(sms)
    for (wa  in resp.whatsapp)  sendWhatsApp(wa)

    Thread.sleep(pollIntervalMs)
}
