How can I get credentials ?

You can get Log In with PayPal credentials as long as you have a PayPal account in your country. To get Log In with PayPal credentials, create an application on the Applications tab on developer.paypal.com. Formerly, credentials were obtained at devportal.x.com. If you had an application at devportal.x.com, and had credentials for that application, your application and credentials have been migrated to the Applications tab on developer.paypal.com. The credentials will continue to work and your apps will continue to work.
