PayPal Developer Sandbox API Credentials do not provide username, password and signature

Question

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 address
• Client 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.

Answer 1

• client ID+secret are API credentials from a REST App , which if for sandbox mode will be tied to a particular sandbox account when the app is created

• For the old classic NVP/SOAP API Username/Password/Signature credentials, go directly to the sandbox account list and in manage accounts (...) select View/Edit account, second tab.
