PayPal to Braintree API Change

Our current site uses paypal's integrated processing and we need to have it changed to use braintree. API Docs: [login to view URL] Here is where it uses the credit card processing API on our site: 1) go to www.*.com/[login to view URL] 2) use **/** for login 3) Click "Upgrade" button on the ad that is not upgraded 4) Tick "Silver" and "Credit Card" 5) Forwarded then to credit card form. This current old way was with paypal, we need to change it out for braintree and add function of customer ticking to save card for future use. Then on future visits to this credit card for page they will see their saved card that they can then just click Submit without having to reenter their information every time. Will need to also have a link to edit card on file when there is a card on file. Along with add a link to their member area here: ****/[login to view URL] that will allow if they have a card on file to edit it any time they wish as well. Now keep in mind we cannot store actual cards on our system. We store a token/string that braintree gives us after a successful store on their server of someones credit card information. Need the credit card form to submit to Braintree all user data and also be sure to carry thru these hidden values: invoice sid amount v And then... Upon successful charge submit those hidden values and other values to the [login to view URL] script as you will see the notes in that script that indicate the area that needs to execute upon a successful charge and then a failed charge All existing code that is being integrated with is simple php. Also need a way for users to setup from their ****/[login to view URL] page a link to click to join the "VIP Seller Program" and when they click on that it sets up a subscription of every 30 days billing customers card $39. When a user has an active subscription setup, please create a db table called "vip" with "user_id"|"1" and then when they cancel or they have a failed charge then on recocurring charges to their card the "1" would change to a "0" as not active membership. Need a link on same sign up page for membership to then once setup to cancel membership or change card on file. Please only apply if you can help fix this today and have experience with PayPal API so that braintree api is no harder. Thank you!
