Hi, I have been coding bitcoin payment by using bitcoin API before, and actively working and mining on cryptocurrency. You must be new to this bitcoin system, actual bitcoin payment do not need to get customer bitcoin address before payment, whereas you will generate an unique address for this customer for payment. And you will generate a single unique address for each customer, this is how you will keep track of customer payment.
And I assumed that you do not need integration to your wordpress, right? 2 pages of forms:-
1) Input of customer email.
2) Showing your bitcoin address and waiting for customer payment. Payment status will update in this page once payment done.
Please correct me about the spec. And I will deliver earlier than 10 days, should be in 7 days, I just put 10 days for safe because the detailed spec haven't confirm yet. Thank you and have a nice day~~
