When your account is created you are to request an API Certificate within your PayPal account.
Security note:It is recommended to keep your certificate outside web root folder and upload it one level up, for example in the folder /home/yourhomefolder/ and not in 'htdocs' or 'public_html' subfolder which is usually your web root folder, so no one can download your PayPal security certificate via web and use it for hacking your PayPal account.
