Error: You need to have a valid payment method associated with your ad account before you can create ads.
You haven't linked payment method in Ad Account, that you are using to create an Ad. You can link a bank card (though in this case there is no minimum payment, we do not recommend the use of virtual cards, because Facebook is afraid of fraud and often blocks such accounts) or to sign a direct contract with us and pay by wire transfer (minimum budget is $3000).
To sign the agreement, write to us email@example.com
To link your bank card a map, you must go to the Business Manager https://business.facebook.com/settings/ad-accounts
