I created a mvc project with AspNetWebHooks TrelloReceiver (.net 4.5) and deployed it on appharbor. In the web.config I wrote the following:
<add key="MS_WebHookReceiverSecret_Trello" value="My Secret"/>
And when the request comes, in the logs I see the following:
The WebHook signature provided by the 'x-trello-webhook' header field does not match the value expected by the 'TrelloWebHookReceiver' receiver. WebHook request is invalid.
As a secret i'm using my Trello Oauth token. What could be the problem?
