Update Account Preferences
Updates the account’s preferences. Each top-level key present in the body is replaced as a whole; omitted keys are left untouched. ads_payment_methods always requires a primary entry. backup is optional when the primary is platform_balance — omitting it removes any configured card — while a card primary requires a platform_balance backup. A platform_balance entry may omit id to use the account’s own balance ledger. Changing which funding sources are configured requires a user token, while account API keys may only swap primary and backup.
