You can easily integrate Aura frames with Dropbox using IFTTT. First, you need to download the IFTTT app and create an account.
Once you have created an IFTTT account follow these steps to sync Dropbox photos with the Aura app:
Open the IFTTT app and search for "Aura Frames"
Scroll down to "Send new JPEG files from Dropbox to your Aura Frames"
Scroll down to where you see "Subfolder name". Please tap the bar underneath to name the folder that you plan to add photos to.
Scroll down to "Which Frame?" and select the frame that you would like the photos uploaded to.
Your Dropbox has now been connected! Be sure to click "Finish" on the final screen.
Open your Dropbox account and add the photos you want integrated with the Aura app into the designated dropbox album.
Your photos will automatically be uploaded from Dropbox onto the frame!
