Status URL
The status URL provides a way of sending status information about the app's status to a web site and for the web site to send commands back to the iPad. It can be used as a webhook to send information to your website or to online tools such as Integromat or Zapier.
When enabled the app will send an HTTPS POST request containing information about the app to the status URL at regular intervals. The web site receiving the HTTPS POST request can send a JSON response containing commands for the iPad to execute such as login details or sync information.
The status URL can be enabled in the App Settings screen by setting the URL to call, the update interval and an optional password.
Status Information Sent by the iPad

The POST parameters are:
auth: SHA1 hash of the vendor id + time + password
hash: reserved for future use
time: the time since the Unix epoch - also used to calculate the SHA1 hash for the auth parameter
request: the HTTP POST request type. Currently this will always be "ipad status"
username: the user name if the iPad is logged in
name: the name of the iPad
model: the model of the iPad
user_id: a unique string identifying the username
id: the vendor id of the iPad - also used to calculate the SHA1 hash for the auth parameter
status: the status of the iPad or the screen currently being displayed when in photo booth mode
info: a JSON string providing more detailed information about the status of the app
Sending Commands to the iPad in the Response String
The web server can send a JSON string containing commands in the body of the response to the POST request.
WARNING: Please take care to validate the POST request (e.g. by only responding to known verndor ids and checking the auth parameter) before returning sensitive information such as the username and password
The following commands are currently supported:
JSON command |
Description |
{"cmd":"login","user":"<username>", "pw":"<password>"} |
Login using the given username and password |
{"cmd":"logout"} |
Logout |
{"cmd":"sync","method":"get","eventSyncServer":"<URL>"} |
Sync using GET and the given sync server URL |
{"cmd":"sync","method":"post","eventSyncServer":"<URL>","eventSyncServerPostPassword":"<password>"} |
Sync using POST and the given sync server URL and password |
{"cmd":"sync","method":"dropbox","dropboxPrefix":"<prefix>"} |
Sync using Dropbox and the given Dropbox prefix |
{"cmd":"start","event":<event_number>} |
Start photo booth by running the given event. Set <event_number> to 0 to run the first event in the list of events, 1 to run the second event etc. |
{"cmd":"exit"} |
Exit photo booth mode and return to the start screen |
{"cmd":"update"} |
Sync the current event using the current sync settings |
{"cmd":"updateAll"} |
Exit photo booth mode and update all events using the current sync settings |
{"cmd":"email", "to":"<email_addr>"} |
Email the iPad's status together with a copy of the journal.txt file and the settings.xml file to the given email address. A screenshot can be included by adding "screenshot":true to the JSON response e.g. {"cmd":"email", "to":"<email_addr>", "screenshot":true} The email server can be specified by adding the SMTP server, username, port number and password to the JSON response e.g. {"cmd":"email", "to":"<email_addr>", "server":"<smtp_server>", "port":<port_number>, "user":"<username>", "pw":"<password>"} |
An optional "next" value can be added to the command to specify the interval in seconds before the next status update from the iPad (this overrides the <statusUpdateInterval> setting).
e.g. login and send next status update in 60 secs: {"cmd":"login","user":"<username>", "pw":"<password>", "next": 60}
Sample PHP Script for responding to status updates
The sample PHP script below shows how the status URL can be used to log information about the app status, log iPads in and send commands to iPads.
<?php
// ipad_status.php
//
// PHP script to log status information sent by iPads running Breeze Booth for iPad
// and to return commands to the iPad.
// To enable iPad status messages set the following tags in the settings.xml file on the iPad:
// <statusUrl>https://yoursite.com/ipad_status.php</statusUrl>
// <statusUpdateInterval>600<statusUpdateInterval>
//
// statusUpdateInterval is the update interval in seconds. Set this to 0 to disable updates.
// In version 1.1.2 of Breeze Booth for iPad the update interval can be overridden by adding
// a "next" value to the JSON response.
//
// Sample JSON data sent in the info argument:
// {
// "version":"1.0.5",

// "availableInMB":36142,
