(JavaScript) Dropbox: Access Your Own Account

To programmatically interact with your own Dropbox account, such as for uploading, downloading, listing files, etc., go to the Dropbox app console and create an application. Then generate an access token in the online app console as shown in the screenshot below. The access token does not expire, and can be used to access your own account from your own non-web application.

The example code, located below the screenshot, shows how to list the files in the root folder.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// Connect to the www.dropbox.com endpoint.

var port = 443;

// Success is indicated by a 200 response status code.
if (rest.ResponseStatusCode !== 200) {
    // Examine the request/response to see what happened.
    console.log("response status code = " + rest.ResponseStatusCode);
    console.log("response status text = " + rest.ResponseStatusText);

        var ckdt = new CkDateTime();
        success = ckdt.SetFromTimestamp(jsonResponse.StringOf("entries[i].client_modified"));
        // The date/time can now be converted to many other formats, or the individual parts
        // can be accessed.
