I'm trying to create a checkout using Checkout API, my app is a sales channel and has the access of "writing_checkouts". The product is listed on the sales channel but when I try to create a checkout, the request-response in 200, return a complete checkout object, but there is no field added like email, line_items or shipping address. Here is the example code:
If you are still experiencing this issue, would you be able to provide the 'x-request-id' header from the response to any of the requests you have made to the Checkout API. This will allow me to check our internal logs.
