Using the Methods API you can retrieve a list of the payment methods currently active on your profile. This is useful especially if you would like to integrate the payment method selection into your own checkout flow, since it allows you to automatically load in all available payment methods.
For payment methods with issuer selection such as iDEAL, you can also retrieve the current list of issuers via the Methods API.
For more information on customizing your checkout experience, see Build your own checkout.
Payment methods can be activated via the Mollie Dashboard or via the Enable payment method endpoint on the Profiles API. Payment methods are activated per profile. If you run multiple websites, you can create a profile for each website and activate payment methods for each profile separately.
