Regional Payment Methods
Use address conditions to choose among payment methods that are already configured for the website and country.
For example, a DACH profile can be assigned to the intended customer groups and require a shipping country of Germany, Austria or Switzerland. Its allowed list might contain the store's existing bank-transfer and card methods.
Create another profile for other countries or allow Magento's normal methods when no profile matches. Test each address, especially the exact country boundaries and virtual orders, which use the billing address for condition evaluation.
Payment Profile cannot make an integration available in a country where that payment module itself rejects the quote.
