"BILLING" Option is not working with paypal orders checkout API for landing_page paramter.
I'm trying to use the paypal ordering APIs to create a payment flow where I send the product details and I want the user to enter the credit card details or paypal account to complete the payment then registering the web-hook and the return_url to confirm the order, I tried to use the landing_page option to be setup to "BILLING" as the documentation says, but I keep getting
"details": [ {"field": "/payment_source/paypal/experience_context/landing_page","value": "BILLING","location": "body","issue": "INVALID_PARAMETER_VALUE","description": "The value of a field is invalid." } ],then I tried to use an example from their postman collection which is referenced in their docs, and I got the same error
Here is my full request without the access token
