Trello API credentials for a server based integration
Go to this page and make a note of your key.
Follow the link to “Token” to do the oauth dance and get a token.
Once you have noted your key and token, calling the API is very simple.
I spent hours over a three day period of circling through Trello’s docs trying to find where to create apps so that I could get a set of keys and tokens for consumer and app in order to do the oauth dance.
If you have landed here from the internet in search of an answer to the question of “How do I get a set of credentials that I can use in a server context and call the Trello API”, I hope this helps.
