How to Set Up a PayPal Checkout

1. Go to paypal.com to activate a PayPal business account (See Resources). There is an 'Account Login' window at the opening website and select the 'Sign Up' link. Follow the on-screen sign-up information and select the business account when prompted.
2. Open the main page of the PayPal business account. Log in using the user name and password.
3. Select the 'Profile' navigation tab at the top of the site. Find the 'Account Information' category. Select the 'API Access' option, then the 'Request API Credentials' and click 'Get Started.'
4. Select the 'Credential Type' as 'API Signature.' A form will be displayed for 'API Credential Request.' Fill out the form in its entirety and click the 'Submit' button when finished.
5. Copy the user name and password created for the API certificate and then download the certificate's file to the computer.
6. Apply the credentials for the PayPal checkout to the website. Log in to the website settings and apply a replacement checkout process. Enter the user name and password for the API credential and upload the file to the website as prompted, then save the changes. When the checkout button is clicked, the website will be directed to PayPal to finalize the transactions and, once finished, be redirected back to the initial website.
