Do you know why the payload is a string rather than a hash ?What format is the data being posted in (form data,json, xml etc ?) It seems to me that your first problem is to solve this - even if you were to solve the strong parameters bit presumably your code is expecting params[:user] to be a hash

The payload is a string because the app was generated using rails-api new myapp rather than rails new myapp.  I am using rails-api because I am doing all interactions with the rails app in json.  Using rails-api eliminates all of the rendering code and keeps heroku happier from a memory usage point of view.

When I generate the exact same app using just plain rails new myapp it responds correctly to the incoming json with its own json results.  In other words, params(:user) returns an object which responds to the permits method with rails but the same code returns a string with rails-api, raising the NoMethod exception.

I have found many "solutions" to this on the web (so I am not the first to encounter it), but for some reason none of them work for me.  The explanation below gives more technical details  (this one came from StackOverflow):
