Connecting Dropbox to your ownCloud installation requires only a few steps. Then you can easily keep a Dropbox folder in sync with an ownCloud folder. This guide assumes you already have a Dropbox account.
Install the External Storage Dropbox app from the ownCloud Marketplace
Click Market in the ownCloud web UI drop-down menu on the left side
Go to the Storage category
Select External Storage: Dropbox App
Next, you need to create a Dropbox app. To do that, open the new app creation form, where you see three settings:
"Choose an API" –> "Scoped access"
"Choose the type of access" –> "App folder"
"Name your app"
Read and agree to the Dropbox API Terms and Conditions before clicking the blue Create app button. After you do that, the settings page for the application loads.
|Redirect URI: Here you must enter the exact URL of the page where you configure the storage.
When configuring as an admin:
When configuring as a user:
Take note of the App key and App secret since you’ll need them in the next step.
Return to the ownCloud web interface. Under, check the Enable external storage checkbox if it’s not already checked. Then, in the drop-down list under External storage, select Dropbox V2.
Then, you need to provide a name for the folder in the "Folder name" field and a "client key" and "client secret" under "Configuration". The client key and client secret values are the "App key" and "App secret" which you saw earlier in your Dropbox app configuration settings.
After you have entered these values, click Grant access. ownCloud then interacts with the Dropbox API to set up the new shared folder. If the process is successful, a green circle icon appears at the far left-hand side of the row next to the folder name.
After a Dropbox share is created, a new folder is available under "All Files" with the name you provided when you created the share. It is represented by an external share folder icon as in the image below.
This links to a new folder in your Dropbox account underwith the name of the Dropbox app that you created.
Now, if you add files and folders in either the new Dropbox folder or the new ownCloud folder, they will be visible in both after they’ve been synced.
