I can’t make in app purchases

See if any of the following articles can help:

• Payment methods you can use in the iTunes Store, App Store, and iBooks Store - Apple Support
• If your payment method is declined, or you have billing issue with a previous purchase in the iTunes Store - Apple Support

Hi

Go to iTunes main page bottom of page apple I'd click that view I'd Go to manage payments check your credit card details are correct.

If you don't have a credit card buy a iTunes gift card redeem at the bottom of iTunes page.

Cheers
