Support for Egnyte is deprecated and will be removed in a future version of SyncBackPro.
During the authorization procedure (through SyncBackPro), if you receive the following error from Egnyte then most likely you have registered your API Key as being Private:
{"errorMessage":"Incorrect request type GET for resource owner flow. Please check the documentation and try again."}
You must use Publicly Available Application for the type. Contact Egnyte support for help changing the type.
