Is there any API exists which we can configure to our admin panel and course will automatically added to In-App? Please help me and save my life...

use a consumable 'token'. The user buys one or more of these tokens through an IAP. Then they exchange one or more tokens to get access to your content. Your app keeps track of the tokens that the user has puchased and used. It is appropriate to use something like the user's iCloud Key Value file to allow the user to gain credit for their use of the token on all of their devices. That is, although it is a consumable IAP the purchase is really a non-consumable so you need some way of 'restoring' a purchase.

Is there any way to change price of in app purchase dynamically and provide instalment feature of the content
