Thank you!

you can use both but Certificate having some restriction.

  • API Signature: A user name, password, and a unique string of numbers and letters that identify your account. Because API Signature credentials don't expire, they're easier to implement and more commonly used.
  • API Certificate: A user name, password, and a downloadable certificate that identify your account. API Certificate credentials are valid for three years, and you must renew them before they expire. PayPal recommends this method for optimal security.

Thank you CS User!
