I need my e-commerce store that currently runs on shop-script premium switched from accepting paypals API Certificate to accept paypals API Signature.
Shop-Script Premium only supports the API Certificate, so the code would need to be changed in order to accept the API signature.
I am using paypal website payments pro.
Paypal only allows you to use one or the other. I would need you to backup the site first and would need this done virtually seamlessly.
