Dropbox API

Dropbox does offer an API you can use for listing, uploading, and downloading files, among other operations. You can find everything you need to get started with the Dropbox API, including documentation, tutorials, and SDKs here.

To get started, I recommend reading the Getting Started Guide. For information on how the authorization process works, including information on access tokens and offline access with refresh tokens, check out the OAuth Guide. And for information on interacting with files, refer to the File Access Guide.

Hi Zaidwithdkg,

Most simple way would be installing official Dropbox application and put your files in Dropbox folder. 😁 Joke. Using some of the family of upload endpoints (depending on your file size and their count) would do the trick. Of course, there are corresponding methods in all supported Dropbox SDKs if you use some of them.

Hm..🤔 I have no any idea of such a "offline access token". Where do you see such a thing? 🧐 Don't read untrusted sources!

Access token is used for call to all regular API endpoints and currently is supported only short lived access token. There was time when was possible to choose long lived access token too, but it impossible now. For long term access you need refresh token usable for "refresh" (regenerate in fact) the access token. The refresh token doesn't expire automatic and can be used till revoke (either by application itself or by user). You receive refresh token when you perform OAuth2 flow with offline access type.

Hope this helps.
