Where to find the parameters definitions ?

[Andy-d-g]

Hello, i'm trying to use your API but I can't find the type definition of the parameters.

For exemple :

Endpoint :  post /order/cart/{cartId}/webHosting 

duration: Duration
planCode: string;
pricingMode: string;
quantity: long;

Where am I supposed to find the expected value for pricingMode | planCode | duration ?

Thank you and have a good day
