Obtaining API Credentials
Creating an API Certificate
50 August 7, 2012 Express Checkout Integration Guide
6. Click Done to complete the process.
Creating an API Certificate
Create an API certificate only if your website requires it. Typically, you want to create an API
signature for your credentials instead.
You must have a PayPal Business account to create an API certificate.
NOTE: The certificate for API credentials is not the same as an SSL certificate for your
website; they are not related to each other.
If you do need a certificate, follow these instructions:
1. Log in to PayPal, then click Profile under My Account.
2. Click My selling tools.
3. Click API Access.
4. Click Request API Credentials.
5. Check Request API certificate and click Agree and Submit.
