I have 2 RESTful Rails apps I'm trying to make talk to each other. Both are written in Rails 3 (beta3 at the moment). The requests to the service will require the use an api key which is just a param that needs to be on every request. I can't seem to find any information on how to do this.
You define the url the resource connects to via the site= method. There should be an equivalent query_params= method or similar.
There is one good blog post I found related to this and it's from October 2008, so not exactly useful for Rails 3.
Update: I had a thought. Would a small Rack middleware or Metal be the answer to this? It could just pass through the request, tacking it's api_key on.
