I am building an API that will import order's information from ETSY to a proprietary back office platform.
However, while creating the OAuth connection, I got this error: "Fatal error: Class 'OAuth' not found in..."
I did some research and apparently it is because OAuth is not enabled in my website's server. After contacting the provider (ipage) they said it is not activated in their server and it is in the pipeline of future developments.
Is there any alternative to Authenticate for ETSY?
