Question posted in 
I have gathered some functions and bundled them into a single Google Scripts file that I use with Google Sheets. The functions are: (1) getTwitterUserFollowers(id), (2) getTwitterUserFollowing(id), (3) getTwitterUserName(id) and the (4) postBlockTwitterUser(id).
While the first 3 functions work perfectly, I can’t get the 4th to work (the postBlockTwitterUser(id). Keep on getting:
"Request failed for https://api.twitter.com/1.1/blocks/create.json?screen_name=EladRatson returned code 403. Truncated server response: {"errors":[{"code":220,"message":"Your credentials do not allow access to this resource."
What am i doing wrong?

You’re trying to use app-only authentication OAuth, but you need to use 3-legged authentication with a user token in order to use the blocks endpoint. You’ll need to modify your code to include all four tokens (consumer key and secret and user token and secret) if you want to post to that endpoint.
@andy-piper can you please modify the above code for 3 legged authentication?
I am also using the above script, but don’t know how to post tweets using it. I have the access token and secret but don’t know how to use it.
