PayPal API credentials for sandbox

Question

I'm trying to implement recurring payments with PayPal in PHP. I found this example, which I'm looking into, but I need some API credentials. I created a PayPal sandbox account, and from there I created a merchant account. I'm trying to get the API credentials for that sandbox merchant account to replace the values in the example, but I can't find where. All the guides I find point to non-existant parts of the sandbox user interface. Does anyone know where I can find the API credential details for sandbox merchant accounts?

Thanks.

Answer 1

I'm beginning to I loathe PayPal. Spent an hour on their site looking for this, only to find it here on SO (works as of Oct-2014):

Live: https://www.paypal.com/us/cgi-bin/webscr?cmd=_login-api-run

Test: https://sandbox.paypal.com/us/cgi-bin/webscr?cmd=_login-api-run

Answer 2

To get API credentials in sandbox you must use the API Credentials menu in sandbox itself, instead of logging into the sandboxed account.
