I have an application that downloads new software to an embedded processor (TI CC3200) by using the Dropbox API. It just stopped working. It worked fine the day before yesterday, but now every request for the file to download returns a 403 error.
If I delete the file from the download directory on Dropbox, the embedded application correctly figures out that there is no file to download. If I place the file to download in the directory, I always get the 403 error.
I know the API will be deprecated in June of 2017, I will be changing the application before that.
Solved! Go to Solution.
This is diagnostic output from our embedded application when this transpires. I have redacted the API keys.
