[erlang-questions] Twitter Account Activity API (webhooks) problems

[Peter Andersson]

Hi Marc,

Just wanted to let you know that I got my problem solved thanks to you. I
used erlang-oauth to generate the signature, but not to create the POST
request to Twitter. It looked to me like the form of the erlang-oauth
request did not match the Twitter API spec. However, reading the Zotonic
twitter client code I noticed that it uses oauth:post/5, so I checked the
form of this POST request again, compared it to my own, and realized I had
made mistakes (I must have misunderstood the Twitter API docs).

Thanks again for helping! I truly appreciate it!

  Peter
