How to save a file from Dropbox link in my Dropbox - dropbox

If my client choose a file from Dropbox using Dropbox Chooser and we have a link like https://dl.dropboxusercontent.com/1/view/og7hvjnt7p57jjw/Penguins.jpg. Now if client removes file from his Dropbox account we have nothing so my question is how can I add this file to my Dropbox using PHP instead of Dropbox Saver?

You can use a normal HTTP GET request to download the file from the link while the link is still valid. (Note, the "direct" link type you have in your question expires after four hours.)
Then, you can use the Dropbox API to upload the file to your own Dropbox account:

The kind of Dropbox link you're referring to isn't a "direct" link, but rather a "shared" link, where the link itself points to an HTML preview page, where the user can download the file if they want. You can find information on this feature here:
https://help.dropbox.com/files-folders/view-only-access
Dropbox does offer an API you can use for listing, uploading, downloading, and sharing files, among other operations. You can find everything you need to get started with the Dropbox API, including documentation, tutorials, and SDKs here:
https://www.dropbox.com/developers
Dropbox does offer a .NET SDK in particular:
https://github.com/dropbox/dropbox-sdk-dotnet
To create a shared link for a file or folder using the .NET SDK, you would use the CreateSharedLinkWithSettingsAsync method:

Can I upload files from a custom website form to Dropbox?

I have clients uploading files directly to my Dropbox folder. I was curious if I can build a website form that uploads the file to my Dropbox folder and also saves the forms data to my server with a reference to the file that was uploaded to Dropbox? They are legal documents and I don't want to worry about security if Dropbox handles that.
It looks like it should definitely be possible.
You would have to use the dropbox api:
https://www.dropbox.com/developers
https://github.com/dropbox/dropbox-js
There are some javascript examples that would likely be what you would need to go directly to dropbox without going to your server first.

uploading files to Dropbox, bypassing authorization page?

I have a form with some upload file fields, and I want to store the files in a Dropbox folder. However, the API always asks you to register before uploading files.
Does anyone knows how to do it without having to go through the authorization page ??
I would like to click upload, and directly upload the file to my repository.

Using dropbox Chooser drop-in to retrieve a non-expiring link to files

I would like to use the Chooser drop-in to select a file from dropbox and then synchronize my app with that file occasionally in the background.
https://www.dropbox.com/developers/dropins/chooser/js
A scenario would be:
List item
User selects file.
File uploads to my app.
User returns to my app a few days later after modifying the file in dropbox.
My app should synchronize and pull down that particular file (without again displaying the Chooser drop-in).
The problem is that the Chooser provides an expiring link to the file:
"direct" is an expiring link to download the contents of the file
I can use the Core API exclusively which would work, however I would have to build my own UI to browse the user's dropbox directory. Ideally, I'd prefer to not introduce the world to another file browser; Dropbox has a file browser - and people are familiar with it. Is this possible?
Thanks,
You can just get a preview link and convert it. See https://www.dropbox.com/developers/blog/53/programmatically-download-content-from-share-links.

Dropbox Application; Is it possible to check when a folder or a file is created or modified?

Is it possible to check when a folder or a file is created or modified in my Dropbox Application's folder?
All right, I found the answer.. Developers who want to get information of changes user did in application can use dropbox Delta API or REST API Delta URL..
dropbox.com/developers/reference/api#delta
"https://api.dropbox.com/1/delta" URL in REST API returns last changes as a Json Object.
