Could not get preview url while searching for preview urls
I am trying to search dropbox files inside my application. Although I am bale to find the folders and the files there is no way I can get the preview url of them so that I can redirect the user to th...
Sapu21 , the 'preview_url' is only available for shared items. It won’t be possible to retrieve a preview_url if the folder or file is not shared. Once you share the folder or file, the preview_url will be provided in the metadata within the response object.
A workaround for this case would be implementing the 2/sharing/create_shared_link_with_settings endpoint to create a shared link to your file or folder. If you use the settings parameter with the value 'audience: no_one', this will set the link so that it can't be used by anyone. The link will only direct the user to the content and will not grant additional rights to the user.

Hey thanks a lot for the workaround..can this link which we are getting be used multiple times to view the file or the folder? Suppose if we store the link as a string in our db. Also can you please explain this part

Yes, these links can be used multiple times.
When using 'audience: no_one', the shared link itself does not grant any access. Someone who gets the link wouldn't be able to use it to access the file content unless they already have access to that file via their account anyway, such as if the file is in their account or in a shared folder they already have access to. That being the case, this kind of link is a good way of being able to link to the file but only for accounts that have access anyway.
Thanks a lot
