Braintree Payment Gateway, Mailchimp Trigger API Integration - Basic Project

We are looking at integrating Braintree as a way of customers buying tickets to events and subscribing as recurring members (with a login panel to cancel their subscription). We need the option for customers to add their name, email address and the ticket quantity (£10 per ticket) or to register/login and manage their membership recurring fees. When transactions are successful we need to keep a log of these in a SQL database. All I need is the PHP pages for the checkout process and it to feed into Braintree transactions and a MySQL database with the ticket details/customers/members. When a purchase is successful we also need the API trigger into Mailchimp, to send an event ticket email. Details of the pages are as follows- - Event Ticket Purchase (Non-Recurring Payment) with 'Name', 'Email' and 'Ticket Quantity' to store in SQL database - Event Ticket Confirmation Page - Upon Successful Payment - Membership Subscription Purchase (Recurring Payment) with 'Name', 'Email' and 'Password' to store in SQL database - Membership Confirmation Page - Upon Successful Payment - Membership Login - To login using password setup in subscription purchase - Membership Homepage - To cancel recurring payments and update customer details
