Why do it: If no payment methods have been configured in the system yet, you need to add at least one to be able to receive orders.
Procedure:
1. Access the Checkout editing module.
2. In the first section (Content), scroll down until you find the box titled Payment Methods.
3. Inside this box, if there are no active methods, click the Add Payment Methods button.
4. An external module for configuring payment methods will open. Complete the configuration and save the settings in that module.
5. Once the external module is saved, the Payment Methods section in the Checkout will automatically update, showing the newly added methods.
6. Select the checkboxes for the payment methods you want to enable for this specific checkout.
7. Proceed with the other steps of the module and, when finished, click Save Changes to apply the Checkout settings.
