Question about Paypal Sandbox
Hi. When I run the Checkout Wizard, it has a Checkbox that's already checked to opt to use the Paypal Sandbox for testing. I do want to use it and I do have a Paypal Sandbox, but my questions are:
1) Do I put the Sandbox API Credentials or the real credentials in?
2) When I'm ready to go live, do I just change the credentials in the PHP page to the real ones? Or what do I have to do when I'm ready to go live to change to the real credentials?
