Why is it important to renew my API Certificate?

API Certificates are used to authenticate you to PayPal APIs. If your Certificate expires, PayPal can't authenticate you as a valid API user. As a result, you won't be able to process any transactions via the APIs. If your Certificate has expired, you can renew or change your API Signature or Certificate credentials.
