    Front supports plugins. A plugin is a small web application that can communicate with Front using a JavaScript API. It allows you to extend Front with new features, making it possible to connect it with other tools you use and optimize the workflow of your team:

    Plugin example

    Creating a plugin

    You can use any web framework or library you wish: it's just a web page that can communicate with Front. It has to be hosted on your servers and include our library. Just add:

    <script src=""></script>

    To create a new plugin, go to > Plugins & API > Plugins ans click on "Add a plugin":

    Add a new plugin

    We provide a small sample plugin that shows some basic things you can do using our Javascript API. You can check the code on If you want to test directly, you can even set the plugin URL to be to see what the basic plugin can do.


    In order to avoid compromising your data, every time the plugin SDK is loaded, Front will check if the plugin's current URL matches the one saved in the settings. If it doesn't, no data will be sent to it. This is why we recommend designing your plugin as a single page applications.


    On your side, it might be desirable to ensure that your plugin is indeed requested by Front, especially if it displays confidential information.

    Front provides a simple way to verify that your plugin is requested by Front. In the settings of your plugin, you will see an authentication secret. This secret will be passed as a query parameter named auth_secret when requesting your plugin.

    Plugin authentication

    If you need any help in getting your plugin working, would like more information or a new feature please drop us a line at we will be happy to help.

    Mobile restrictions

    Plugins can be used on Mobile devices directly from a conversation. Some helper methods have not been implemented and will not work on iOS and Android:

    - insertHTML
    - setPanelWidth
    - updateDraft
    - addTopic 

    Getting events from Front

    Front.on('conversation', function (data) {
        // triggered when a conversation is loaded
    Front.on('no_conversation', function () {
        // triggered when no conversation is selected
    Front.on('panel_visible', function (visible) {
        // triggered when your plugin becomes visible or invisible
        // you can also test Front.visible

    Every time the current conversation changes (for example, when you click a new conversation in the list), an event is sent to our library.

    The data object sent to the callbacks of the event contains 4 fields:

    The contact object will look like this :

      "id": "crd_55c8c149",
      "handle": "",
      "initials": "J",
      "display_name": "John Doe",
      "description": "",
      "avatar": null,
      "color": "hsl(47,60%,70%)",
      "source": "email",
      "role": "reply-to",
      "num_notes": 0

    The conversation object will look like below, for clarity sake some objects have been removed:

      "id": "cnv_55c8c149",
      "link": "",
      "message_type": "email",
      "status": "unassigned",
      "replied": false,
      "reacted": false,
      "num_messages": 1,
      "contact": {}, // Similar to the contact JSON above
      "assignee_id": "tea_55c8c149",
      "inbox_ids": ["inb_55c8c149"],
      "follower_ids": ["tea_55c8c149"],
      "tag_ids": ["tag_55c8c149"],
      "seen_by": ["jane"],
      "subject": "test again",
      "summary": "Just testing some stuff",
      "has_draft": false

    The message object will look like below, message found in otherMessages will not have body field as they are only loaded when expanded.

      "id": "msg_55c8c149",
      "ext_id": "",
      "type": "email",
      "status": "imported",
      "date": 1422909585000,
      "inbound": false,
      "blurb": "This is a test",
      "recipient_opened_date": null,
      "subject": "More testing",
      "body": "This is a test", // body will only be loaded in the first message
      "from": {
        // Similar to the contact JSON above
      "recipients": [
          // Similar to the contact JSON above
      "attachments": [{
          "id": "fil_55c8c149",
          "uid": "1234567890",
          "filename": "chart.jpg",
          "content_type": "image/jpeg",
          "size": "391970"

    Controlling Front

    The javascript library exposes several helper functions to send commands to the app. Most functions accept either an alias or an object returned by Front.fetchInboxes, Front.fetchAllowedTeammates or Front.fetchAllowedTags.



    Unassign the currently selected conversation.



    Assign the currently selected conversation to a teammate.

    Toggle archived


    Toggle the archive flag of the currently selected conversations.

    Toggle trashed


    Toggle the trashed flag of the currently selected conversations.

    Open URL


    Request Front to open a URL. Using a conversation URL (cf: the field link in the conversation object), it lets you open a conversation.

    Compose new message

        from: '',
        to: [''],
        cc: [''],
        subject: 'Optional subject',
        body: 'Optional body',
        attachment_uids: [],
        hide_composer: false

    Open a new message. Will do nothing if an inbox cannot be selected (for example, if you try to compose to a Twitter handle, but have no Twitter inbox).

    The options object accepts the following fields :

    Compose reply

        to: [''],
        subject: 'Optional subject',
        body: 'Optional body',
        attachment_uids: []
    }, replyAll);

    Send a reply to the latest message of the current conversation. Will do nothing unless a conversation is selected.

    The options object accepts the following fields :

    The replyAll parameter will transform a simple reply in a reply all if set to true.

    Compose forward

        to: [''],
        subject: 'Optional subject',
        body: 'Optional body',
        attachment_uids: []

    Update draft

    Front.updateDraft(draft_id, {
        recipients: {
            to: [''],
            cc: [],
            bcc: []
        attachment_uids: []
    }, callback);

    Updates the draft of the current conversation. You can get the draft_id by calling the fetchDraft method.

    Tagging/Untagging a conversation


    You can add or remove tags from a conversation. For this, you will need the alias of the tag. The alias is a URL-friendly, human-readable name for the tag that is unique to your company. You can find the alias of a tag by looking at your browser URL when you click on a tag in Front.

    Moving a conversation to an inbox


    You can move a conversation to an inbox. You can request a conversation to be moved to a team inbox not accessible by the user, but they will get a confirmation dialog (as they will lose access to the conversation).'search query terms');

    Perform a search

    Insert HTML

    Front.insertHTML('Automatically inserted HTML');

    Lets you insert HTML in the message composer where the user cursor is.

    Add topic

        type: 'web',
        name: 'Link example',
        ext_link: ''
    }, function() {

    A topic is an external link attached to your conversation. It has a type, a name and an URL.

    Field Type Description
    type String Type of the topic. Can be either web, github, jira, trello or assana.
    name String Name of the link which will appear on the conversation.
    ext_link String URL of the topic.

    Set Width


    The plugin initially appears with a width of 270px. However, you can request more space very easily:


    Dialogs can be used to ask the user for confirmation or input a value. Use them instead of window.alert, window.confirm, window.prompt.

    Unlike window.alert, Front dialogs are asynchronous and expect a callback.


        title: 'Title of the alert',
        message: 'Body of the alert.',
        okTitle: 'Label of the OK button (optional)'
    }, function () {
        console.log('User clicked OK.');

    The Front.alert() method displays an alert dialog with the optional specified content and an OK button.

        title: 'Title of the report',
        message: 'Body of the report'
    }, function() {
        console.log('User closed the report');

    The method displays an alert dialog with the optional specified content without any buttons.


        title: 'Title of the confirm dialog',
        message: 'Body of the dialog.',
        okTitle: 'Label of the OK button (optional)',
        cancelTitle: 'Label of the OK button (optional)'
    }, function (confirmed) {
        console.log('User confirmed?', confirmed);

    The Front.confirm() method displays a modal dialog with an optional message and two buttons, OK and Cancel.

    The callback will received a confirmed boolean, indicating whether the user clicked OK or Cancel.


        title: 'Title of the confirm dialog',
        message: 'Body of the dialog.',
        okTitle: 'Label of the OK button (optional)',
        cancelTitle: 'Label of the OK button (optional)'
    }, function (val) {
        console.log('User entered:', val);

    The Front.prompt() method displays a dialog with an optional message prompting the user to input some text.

    The callback will receive a val with the text entered by the user (or null if the user canceled).

    Prompt Date

    var position = {
        left: event.screenX - window.screenX,
        top: event.screenY - window.screenY,
        position: position,
        val: defaultDate,
        before: forceSelectionBefore,
        after: forceSelectionAfter
    }, function (date) {
        console.log('User selected:', date);

    The Front.promptDate() method displays a dialog to select a date. It will pass the callback a JavaScript Date (or false if the user canceled):

    Item List

        items: [
            {title: 'Options 1'},
            {title: 'Options 2'},
            {title: 'Options 3'}
    }, function (item) {
        if (item)
            console.log('User selected', item.title);
            console.log('User canceled');

    The Front.fuzzylist() method displays a list of elements with a search field (for quick selection).

    You can pass extra parameters in addition of title. They will still be in the item when the callback is called.

    Copy to Clipboard


    This method will copy a string to the user's clipboard.

    Accessing Front data

    The plugin API enables you to extract some data from Front, always remember that these data are relative to the teammate using the plugin, if teammate A does not have access to inbox B then you will not see inbox B when calling fetchInboxes().

    Fetching data through the plugin API is asynchronous, this means that you will need to provide the js library with a callback every time you want to retrieve data.

    Please also note that the data you extract from these calls is just a snapshot of Front's state when you asked for it, any updates happening afterward will not update the data you received nor call your callback again.

    User Profile

        "url": "/api/1/companies/planet_express/team/bender",
