The following refers to what used to be called the CloudDrive API although it may be called something else these days ?
I set up a security profile, whitelisted it, and got a confirmation email that it had been whitelisted (this was back in 2015 and I've only recently picked this project up again, due to issues I was having at the time).
When I try to authorise using the API, I get a '400 Bad Request. An unknown scope was requested' error.
My request URL looks like this: (obviously the <my client ID> bit is replaced by my actual client ID)
Any suggestions as to what I'm doing wrong, please ?
