var onRequestReferenceData = function () {
    var link = event.data.link;
    var referenceData =  event.data.referenceData;
    var path = event.data.path;
    ...

        "c": event.data.c,
        "fileType": "xlsx",

onRequestSendNotify - the function called when the user is mentioned in a comment.

The message and the list of emails is sent in the data parameter. The comment data is received in the data.actionLink parameter and must be then used in the configuration as the value for the editorConfig.actionLink parameter.

The list of users to be mentioned should be completed by setUsers method.

In version 5.4, onRequestSendNotify event can only be used if onRequestUsers event is set. Starting from version 5.5, there is no such dependency between onRequestSendNotify and onRequestUsers - both can be set independently.

Example
```
var onRequestSendNotify = function (event) {
    var ACTION_DATA = event.data.actionLink;
    var comment = event.data.message;
    var emails = event.data.emails;
    ...
};

var docEditor = new DocsAPI.DocEditor("placeholder", {
    "events": {
        "onRequestSendNotify": onRequestSendNotify,
        ...
    },
    ...
});
```

onRequestSharingSettings - the function called when the user is trying to manage document access rights by clicking Change access rights button.

When the access rights is changed, you must call the setSharingSettings method to update the information about the settings which allow to share the document with other users. If the method is not declared the Change access rights button will not be displayed.

Example

var onRequestSharingSettings = function () {
    docEditor.setSharingSettings({
        "sharingSettings": [
            {
                "permissions": "Full Access",
                "user": "John Smith"
            },
            {
                "isLink": true,
                "permissions": "Read Only",
                "user": "External link"
            }
        ]
    });
    ...
};

var docEditor = new DocsAPI.DocEditor("placeholder", {
    "events": {
        "onRequestSharingSettings": onRequestSharingSettings,
        ...
    },
    ...
});

onRequestStartFilling - the function called when the user is trying to start filling out the ready forms by clicking the Start filling button in the pdf editing mode. If the event is not declared, this button will not be displayed.

When the user clicks the Start filling button, the startFilling method is called to lock the pdf editing (only pdf viewing becomes available).

Example
```
var onRequestStartFilling = function () {
    docEditor.startFilling();
    ...
};

var docEditor = new DocsAPI.DocEditor("placeholder", {
    "events": {
        "onRequestStartFilling": onRequestStartFilling,
        ...
    },
    ...
});
```
onRequestUsers - the function called when the user can select other users to mention in the comments, grant the access rights to edit the specific sheet ranges, or set the user avatars.

Starting from version 7.4, the operation type can be specified in the data.c parameter. It can take two values - mention or protect. Prior to version 7.4, only the mention operation was available with this event.

Starting from version 8.0, the info operation type is added to set the avatars for the users with the ids specified in the data.id parameter.

To set a list of users, you must call the setUsers method which can take different lists of users depending on the specified operation type. The onRequestUsers event is called once for each c type when the corresponding operation is performed. If the setUsers is called with an empty list, then the onRequestUsers event will fire again.

Example
```
var onRequestUsers = function (event) {
    var c = event.data.c;
    var id = event.data.id;
    ...

    docEditor.setUsers({
        "c": event.data.c,
        "users": [
            {
                "email": "john@example.com",
                "id": "78e1e841",
                "image": "https://example.com/url-to-user-avatar1.png",
                "name": "John Smith"
            },
            {
                "email": "kate@example.com",
                "id": "F89d8069ba2b",
                "image": "https://example.com/url-to-user-avatar2.png",
                "name": "Kate Cage"
            },
            ...
        ]
    });
};

var docEditor = new DocsAPI.DocEditor("placeholder", {
    "events": {
        "onRequestUsers": onRequestUsers,
        ...
    },
    ...
});
```

};

var docEditor = new DocsAPI.DocEditor("placeholder", {
    "events": {
        "onSubmit": onSubmit,
        ...
    },
    ...
});

    },
    ...
