Can I show different payment gateways for different countries or locations in my store?

Sure. If you are using the Conditional Payments for WooCommerce plugin, it allows you to create unlimited Conditional Payments rules and configure them for your store. To enable different gateways for different countries/locations, create rules by specifying which payment methods to enable for which country. An example rule could be - Condition: Location is Austria, Action: Enable Payment Method Cash on Delivery. Repeat the same for other locations.
