I am using PayPal classic API. When I try to reach out for the sandbox test account API credentials, I got the empty screen below. Can anyone tell me what is going on?
user2183113's steps didn't work for me - I couldn't find the API credential link.
I ended up just creating a new business account in Sandbox using the same email I used in 'normal paypal', this new Sandbox account comes with its own API credentials already.
