Yes, I’ll test, again, this evening. It might have failed due to a mis-typed Content-type. However, I’m testing with a simple garage door app and don’t want to crush my wife or her car!
Being able to POST to a API is extremely important for my production apps and I don’t want to hard code the access token for security reasons.
I appreciate your advice and I’ll reply with the results of further testing.
NOTE – I believe the content type is “application/x-www-form-urlencoded”, not what you suggested above.
