Our adult website is changing from credit card payment to SOFORT payment. Payment and member management was done by credit card processing site so this all needs to be replaced by new scripts on our own server. First you need to install member management script which stores data in a MySQL database, you can use a ready available free or commercial script or you can write your own script. Then make the scripts connect with the SOFORT payment system API; people buy membership on our site, get directed to the SOFORT interface for payment, when payment is cleared then your script creates an account for this member and sends him an e-mail with payment confirmation and his password. We already have an account with SOFORT, we will give you access to our SOFORT account and to our server.
