I have access to the sandbox API creds but on paypal.com, there is no option to "Request API Credentials" under NVP/SOAP API. it only says "Manage API Credentials" and on click it says "Couldn't confirm it's you".
Though I have put a request from developer.paypal.com. enabled Paypal Here, Personal and Account information on both Live and Sandbox Accounts. but to no avail.
