Make Orders API calls from your server
The standard payments integration provides client-side helper functions to call the PayPal Orders API. These functions make it easy to quickly integrate with PayPal for the first time. However, there are business reasons that making API calls from your server is necessary.
- You have data in a database that you need to look up before you make the API call.
- Your buyers' cards are stored on your server.
- You need to make another API call before you call PayPal.
- Anytime you have data on your server that you need to use for a specific call.
