ZAF Client API

The ZAF client lets your app in the iframe communicate with the host Zendesk product. You can use the client in your apps to listen for events, get or set properties, or invoke actions. The ZAF client also provides additional methods for building apps.


var client = ZAFClient.init();client.get('').then(function(data) {  console.log(data); // { "": "Mikkel Svane" }});

ZAFClient Object

When you include the ZAF SDK on your website, you get access to the ZAFClient object.

<script type="text/javascript" src=""></script>

The ZAFClient object has the following method:


Returns a client object.


var client = ZAFClient.init();

Client Object



Requests context for the app, such as the host and location. Depending on the location, the context may provide additional identifiers that you can use with the REST API to request additional data.


A JavaScript Promise object.

var client = ZAFClient.init();client.context().then(function(context) {  console.log(context);  /*    {      "instanceGuid": "7712c893-bec7-4e00-9db0-87fbb0c12914",      "product": "support",      "account": {        "subdomain": "mondocam"      },      "location": 'ticket_sidebar',      "ticketId": 1234    }  */});


Gets data from the UI asynchronously. For a complete list of supported paths, see:

Some path segments can take arguments that you can specify using a colon syntax. For example, to retrieve information about the options available to the type ticket field, you could call client.get('ticketField:type.options').

  • paths an array of path strings or a single path string

A JavaScript Promise object.

var client = ZAFClient.init();
client.get('ticket.subject').then(function(data) {  console.log(data); // { 'ticket.subject': 'Help, my printer is on fire' }});
// or
client.get(['ticket.subject', '']).then(function(data) {  console.log(data); // { 'ticket.subject': 'Help, my printer is on fire', '': 'Mikkel Svane' }});

client.has(name, handler)

Returns whether or not an event has the specified handler attached to it.

  • name the name of the event
  • handler the handler you want to test
var client = ZAFClient.init();
client.on('app.registered', function appRegistered(e) {  // do stuff});
client.has('app.registered', appRegistered); // trueclient.has('app.activated', appRegistered); // false


Initialize a ZAFClient for another location.

var client = ZAFClient.init();var otherClient = client.instance('9e012b1f-1397-484e-8810-c444b8085e55');
  • instanceGuid - the GUID for the desired instance of the app

An instance of ZAFClient for the requested instance GUID

Note that instances are transient in some locations (like ticket sidebar), so if the ticket tab is closed that instance is destroyed.


This example demonstrates how to open a top bar app from a ticket sidebar iframe.

The app in this example must run in the top_bar and ticket_sidebar locations. The manifest would contain a snippet like this:

{  "location": {    "support": {      "ticket_sidebar": "assets/ticket_sidebar.html",      "top_bar": "assets/top_bar.html"    }  }}

The ticket sidebar app runs the following code:

var client = ZAFClient.init();
var topBarClientPromise = client.get('instances').then(function(instancesData) {  var instances = instancesData.instances;  for (var instanceGuid in instances) {    if (instances[instanceGuid].location === 'top_bar') {      return client.instance(instanceGuid);    }  }});
topBarClientPromise.then(function(topBarClient) {  // opens the top bar app, even if its iframe hasn't been loaded  topBarClient.invoke('popover');});

client.invoke(name [, ...args])


Executes an action identified by the name path parameter, or multiple actions defined in the obj argument, within the product interface. For a complete list of supported paths, see:

Some path segments can take arguments that you can specify using a colon syntax. For example, to hide the priority ticket field, call client.invoke('ticketFields:priority.hide').

  • name the path to call
  • args (optional) arguments to be passed to the call, or
  • obj an object containing invoke paths as keys and arrays of arguments as values

A JavaScript Promise object with the value returned from the method call(s).

var client = ZAFClient.init();
client.invoke('ticket.comment.appendText', 'Help!').then(function() {  console.log('text has been appended');});
// or
client.invoke({  'ticket.comment.appendText': ['Help!'],  'ticketFields:priority.hide': []}).then(function(data) {  console.log(data); // { 'ticket.comment.appendText': value, 'ticketFields:priority.hide': value }});


Requests metadata for the app, such as the app ID and installation ID.


A JavaScript Promise object.

var client = ZAFClient.init();
client.metadata().then(function(metadata) {  console.log(metadata);  /*    {      "appId": 123,      "name": "My App",      "installationId": 12345,      "version": "1.0",      "settings": {        "title": "My Installation Name"      }    }  */});, handler)

Allows you to remove a handler for a framework event.

  • name the name of the event
  • handler the function you attached earlier with on
var client = ZAFClient.init();
client.on('app.registered', function appRegistered(e) {  // do stuff then remove the handler'app.registered', appRegistered);});

client.on(name, handler, [context])

Allows you to add handlers to a framework event. You can add as many handler as you wish. They will be executed in the order they were added.

For available events, see:

See also Working with framework events.

  • name the name of the framework event you want to listen to. This can be framework, request, or custom events
  • handler a function to be called when this event fires
  • context (optional) the value of this within your handler
var client = ZAFClient.init();client.on('app.registered', function(e) {  // go nuts});

Note: As soon as communication with the framework is established, the SDK triggers an app.registered event. You can add as many handlers to app.registered as you like. They're called immediately after the init callback.


Dispatches network requests via the Zendesk Apps framework.

  • options the url of the resource to request, or an object containing a combination of the following properties with their supported values. All values are case sensitive.
options Type Description
