What is the best way to see if OAuth Token is valid?
Make an API to /admin/shop.json request and see if you get a 401.
The response that I get from making an API call to /admin/shop.json for an invalid OAuth Token is:
[API] Invalid API key or access token (unrecognized login or wrong password)
Is this what I should be seeing?
Take a look at your servers response code. It's most likely a 401, but that's how you know for sure that your API request was denied due to invalid access tokens
Thanks Chris! I've found it!
