**We are looking to integrate parts of 5 different systems to work together (simpler than it sounds):** *FastSpring - to handle sales and update secure payments/subscriptions/customer info/checkout/etc. *Our website (cloud app) run with Mysql/php/javascript - so users can manage billing, subscriptions, cancelation with FastSpring etc. *Our marketing website (eg. our blog, etc.) *PostAffiliatePro - integrate affiliate program to handle auto-generating referral links for users (not hard with PAP on your server), and partner programs (links, diff commission rates, banners, ads, etc). *ZenDesk - knowledge base (on the marketing site), submit tickets, manage customer service, tickets. ## Deliverables --Don't apply if you aren't doing the hours yourself. Eg. no programming companies, etc. MUST be an individual-- Our company is finishing up a year of programming on our new web app. We are aiming to launch our beta version on March 1st. Our product is "paid membership" (subscription) access to a cloud app that lets users manage their freelance business from the website. **We REQUIRE high proficiency (minimum 4 years work experience) in the following:** *Strong English *PHP *MYSQL *CSS *JAVASCRIPT *eCommerce security and safety measures (eg.

We would like a central user database - eg. centralized in FastSpring (where the sales are recorded is usually a good managing location). They need to be secure connections - no security risks. We use PivotalTracker and Github for collaboration. We require that you use these. We don't imagine this would take very long for a very talented API, PHP/MYSQL programmer. We can't wait to work with you. **Please SUBMIT the following:** *An example of a API integration you've done. *Your fixed quote
