Payment options for Premium account and sponsored item features

Hi all, I am new to this discussion forum.

I have a question

I am developing an ecommerce app. In which user can sell or buy physical goods. I want to put premium account (paid) functionality in it. also I want sponsored item feature, in which seller can highlight his item by paying a small fee. What should I use for payment for both of the features? in-app-purchase or other third party payment gateway?

It sounds like there are two types of 'products' being sold - the actual physical goods and the premium listing (i.e.'seller can highlight' and 'premium account functionality'). Regarding the physical goods - you cannot use IAP and depending on how you interpret 11.2 you may, or may not, use a 'PayPal' like system within your app. You can use a PayPal like system accessed through your website for the physical goods. Regarding the premium listing - I think you must use IAP for that.
