Where, in PayPal Developer, do I find the API username, password and signature?
I'm looking to update gateways.php to include our client's live PayPal credentials but PayPal Developer seems to have changed so much since I last used it. Could you help me create/locate the API username, password and signature?
You'd also helped us set up an IPN for refunds made in PayPal, in a Sandbox test environment, and we need to make sure that's set up in the new live account.
Hope to hear from you.
