New PayPal Module (Latest API 2.0) Configuration in Standard Variant for osCommerce 4-based systems
To configure the new PayPal module in the standard variant click on Modules, Payment and Online tabs, choose the required sales channel and then click on PayPal Quick Setup button.
We assume you already have your PayPal account so choose Yes, connect it in the pop up window and click on Next button.
In the next pop up window you can either have your own REST API keys on hand and know how to set them up or you can get them automatically from PayPal by clicking on Continue to PayPal button. You can also use PayPal sandbox account to test this functionality first (we assume you would like to get your REST API automatically from PayPal).
Login to your PayPal account as the seller.
Click on Agree and Connect button to proceed.
After you see the success page click on Go back to osCommerce Sandbox button.
Scroll it down and you can see your PayPal keys generated on your PayPal account. In case you chose the option have your own REST API on hand and know how to set them up mentioned above you would see this this page and would need to fill in your keys in the corresponding fields yourself.
Click on Test API Details button. If the API connection is successful click on Close icon and on Update button to complete this process.
The system is ready to get the money.
