Simple file name retrieving using javascript

The Dropbox Chooser is a way to allow end-users to select specific files/folders and send them to the app. Based on your description, it sounds like that's not exactly what you're looking for. The Dropbox Embedder might be a better solution for you though. That lets you supply a (view-only) shared link, e.g., for a particular folder, and displays the contents of that folder on a web site.

Alternatively, if you need a more custom integration, you would need to use the Dropbox API instead. That allows you to programmatically list files and folders. For example, to list the contents of any particular folder, you would use the /2/files/list_folder[/continue] endpoints to list the contents of a specific path, and the results would include the name of each item. By the way, those are links to the documentation for the HTTPS endpoints themselves, but we recommend using one of the official SDKs if possible. Those have corresponding native methods for the HTTPS endpoints. The Getting Started and File Access guides may also helpful if you decide to use this option.

Hello,

I am currently using the ajaz call below to achieve what I need but am still facing issues.

$.ajax({
type: 'POST',
url: 'https://api.dropboxapi.com/2/files/get_metadata',
data: "{\"include_deleted\":false,\"include_has_explicit_shared_members\":false,\"include_media_info\":false,\"path\":\""}",
contentType: "application/json",
beforeSend: function(xhr) {
xhr.setRequestHeader("Authorization", "Bearer ***")
}, success: function(data){
console.log(data);
}
})

Please clarify what you mean when you say you are "still facing issues". For example, share any unexpected error or output.

Sorry about that!

The issue that is appearing now is 

Failed to load resource: the server responded with a status of 400 () https://api.dropboxapi.com/2/files/get_metadata

The entire code I have is this:

<script>

What's in the response body for that response with the 400 status code? It should contain a more specific error message.

Is this what you mean?  

Here's more 

Error in call to API function "files/get_metadata": Your app is not permitted to access this endpoint because it does not have the required scope 'files.metadata.read'. The owner of the app can enable the scope for the app using the Permissions tab on the App Console.

This latest message is what I was referring to. It indicates that the call failed because your app does not have the necessary scope for that endpoint. You can enable the scope on the app's page on the App Console as described. Note that you'd need to then get a new access token as that change does not retroactively affect existing access tokens.
