Purpose of the job is to give me the ideas/solutions to secure API accesses.
You will only need to give us the best way to do that. We will do the job ourself.
We are developing an iPhone App with distant access to datas trough API.
For the moment, iPhone App get access to api with a JSON request like this :
[url removed, login to view]
User need to access directly to the Api without setting any username/password.
Api is almost "public" but only for user of the iPhone App.
