Social Media Integration Login APIs

I have a small kiosk program for my business. I have it setup to login in to facebook, twitter and foursquare. Due to the recent changes to the twitter portion and foursquare API's portion of the website do not work correctly. I need someone skilled in the Twitter API, Facebook API and Foursquare API. All the code has already been written but just needs to be updated to work with new API standards. Here is a description of what I need each social network to be able to do: Twitter Integration: 1. User clicks image that says Tweet about us on Twitter 2. Twitter login page comes up 3. User loges in and automatically Tweets a predefined tweet about our store 4. User is automatically logged out after tweet is successful 5. User is brought to a final screen that reveals a secret word pulled from a database to tell cashier that he/she has checked in. Foursquare Integration: 1. User clicks image that says check in on Foursquare 2. Foursquare login page comes up 3. User logs in and automatically check's in at my location (location information is pulled from a mySQL database that is already established). 4. User is automatically logged out after successful check-in. 5. User is brought to a final screen that reveals a secret word pulled from a database to tell cashier that he/she has checked in. Facebook Integration: (Currently this app works flawlessly and I can use it to demonstrate how i need Twitter and Foursquare apps fixed.) 1. User click image that says check in on Facebook 2. Facebook login page comes up 3. User logs in and automatically check's in at my location (location information is pulled from a mySQL database that is already established). 4. User is automatically logged out after successful check-in. 5. User is brought to a final screen that reveals a secret word pulled from a database to tell cashier that he/she has checked in. Facebook Integration 2: (this method is not setup yet) 1. User clicks Like Us on Facebook to reveal secret word. 2. Facebook login page comes up 3. User logs in and automatically likes my Facebook page 4. User is automatically logged out after liking my page 5. User is brought to a final screen that reveals a secret word pulled from a database to tell cashier that he/she has checked in. The system is already setup just needs some updates. I can demonstrate everything for you over a remote session once project is accepted. I am a Frontend Developer/Designer that as been tasked to complete this project for my company. Please let me know if you have any questions. TY.
