Trying to setup an app with a sandbox account on PayPal. I already had a Business account with PayPal and have created a new application under the Sandbox.
I am provided with 3 credentials by PayPal:
Sandbox account
which has the appearance of an email addressClient ID
Secret
However, using Omnipay with Laravel and it asks me for Username, Password and Signature in the config/env. I have some legacy prod credentials which look nothing like those provided by PayPal above, so can't even make an educated guess.
Thank you in advance.
