REST API URLs
To communicate with the PayPal REST APIs, you'll pass JSON-formatted HTTP requests to the API endpoint in either the sandbox or production environment.
This following sample call, which generates a the next available invoice number in the merchant's account, is made to the sandbox environment for testing.
curl -v -X POST https://api-m.sandbox.paypal.com/v2/invoicing/generate-next-invoice-number \ -H "Content-Type: application/json" \ -H "Authorization: Bearer <Access-Token>"
When you're ready to take your code live, change the base URL.
curl -v -X POST https://api-m.paypal.com/v2/invoicing/generate-next-invoice-number \ -H "Content-Type: application/json" \ -H "Authorization: Bearer <Access-Token>"
