What are client actions?

Client actions are actions  are the actions that a Flock client takes clients take when a user interacts with controls like buttonsSlash Commandsslash commands, and so on, that have been provided by an app. Flock Attachment PickersLauncher Buttons, and so on. 

Flock currently supports three kinds of client actions. They are:

How do I configure a client action?

Different controls have different ways in which their respective client actions can be configured:

...

Opening a Widget

You can use widgets to render web applications inside an iframe or a webview within Flock. They can not only do everything that a normal webapp can, but also interact with the Flock client hosting them.

To open a widget, the following info is required:

  • URL of the widget
  • Type of widget in desktop – it can be either modal or sidebar
  • Type of widget in mobile – this is usually optional. The only acceptable value is modal.

Opening the Browser

You can also choose to open a URL in the browser. To open the browser, provide the following:

  • The URL to open.
  • Whether to send event context or not. When enabled, event parameters are appended to the URL.

Sending an event to the event listener URL

Or if you prefer to remain silent, you can send an event to the event listener URL.

What happens when a client action is triggered?

An event is generated every time a client action is triggered.

The events sent by various controls when a client action is triggered are listed below:

The event name along with its attribute provides sufficient context for the client action.

How do I configure a client action?

There are multiple ways to configure client actions in Flock, all of which are described below.

Developer Dashboard

Use the developer dashboard to configure an action for a Slash CommandLauncher ButtonChat Tab Button or Attachment Picker. Once you have enabled the control, you can select the appropriate action and provide any additional info that's required.

Attachment Buttons

Client actions for attachment buttons are configured while creating the corresponding Attachment. Use the action property of a button to set the appropriate ActionConfig object.

    }]
}

flock.js

Widgets can open another widget or the browser using flock.js.

flock.openWidget("<widget url>", "modal")
Code Block

titleOpening the browser using flock.js
flock.openBrowser("<url>", true);

FlockML

FlockML's action tag can also be used to trigger client actions:

Code Block
languagexml
titleOpening a widget using FlockML
<flockml>click <action type="openWidget" url="<url>" desktopType="sidebar" mobileType="modal">here</action> to launch a widget.</flockml>
Code Block
languagexml
titleOpening the browser using FlockML
<flockml>click <action type="openBrowser" url="<url>" sendContext="true">here</action> to open the browser.</flockml>
Code Block
languagexml
titleSending event to the event listener using FlockML
<flockml>client <action type="sendEvent">here</action> to send an event to the event listener URL.</action>

Can client actions be triggered for users who haven't installed the app?

Yes. Your app may send a message to a user who may not have installed your app, or a group where some users may not have installed your app. When these users interact with this message's attachment (e.g. click on an attachment button, or take some action inside the attachment widget), a client action is triggered.

If you verify that the validation event token sent with the corresponding event is really signed using your app's secret (you should always do this anyways), you can be certain that the event originated from Flock and was actually triggered by the user whose userId is included in the validation event token (even if they haven't installed the app).
