COINBASE API Purchase and Completion

There are two pages that need to be altered for completion. The API creation has already been established with CoinBase. We need software edits and AJAX development to complete the process. 1: A user needs to be able to enter the amount of money they wish to deposit and with one click this is sent to CoinBase. The API is already established. This will most likely need AJAX to be completed. There are specific fields that need to be sent to CoinBase, so this may be more complex than a simple <form>. 2: The other page is the callback page from CoinBase. We need to capture the Merchant Transaction ID as the transaction ID into our database. The purchase amount. The email of the user who made the purchase. The ID of the user who made the purchase. The time the transaction was completed. All of this data will be inserted into our database upon receiving a successful callback from CoinBase. 3: When the information is inserted to our database, an email will need to be sent to that users email who made the purchase. You can use "This is a sample email" With the Subject "Test GPG Email" for testing purposes. We will complete the email form at a later time. Thank you. Ryan
