You can enable and disable wherever payment method you want by contacting the "[email protected]" asking to enable/disable a specific payment method, which will allow you to control the payment methods available to your customers in PayTabs's PayPage. However, you should know that is not the preferable way to perform it if you will frequently change enabling those payment methods a lot, due to the process takes some time to handle.
Example from the WooCommerce plugin.
You definitely can choose which payment methods should appear to the customers while creating your PayPage (whether hosted payment page or even managed/own form one), you are able to do this by passing an array of the only payment methods that you want to display, or just display them all.
'payment_methods': [ 'creditcard', 'applepay', 'amex', 'mada', ... ]
'payment_methods': [ 'all' ]
You can also easily remove this parameter completely and the PayTabs' PayPage will just be generated with all the enabled payments methods in your PayTabs account.
And here's the list of all available payments. Supported with Paytabs.
To use (enable/disable) any payment method from the above-mentioned list, it should be enabled on your account first. To enable any of them, just contact the "customer [email protected]" mentioning the specific methods you want to add/enable.
