Need trello.com integration

Hi We have been using Trello and integrating it's api from last many years. We have the experience of integration of Trello through the API they offer. They offer the Curl requests that will respond with the JSON data and that is what we'll be utilizing. there are two ways to fetch the API data, from private board or the public board. For both the authentication is required. But it is a good idea to integrate the board with any app. Best. Charles.
