Handle payment method
Cetelem requires instance of Redirect Manager in order to be presented to the user:
1const manager = await headless.createPaymentMethodManager('MONEXT_CETELEM')MONEXT_CETELEM must be returned as PaymentMethod.type in the onAvailablePaymentMethodsLoad callback.
When the user has selected the payment method, call the start function. This function automatically:
- opens a popup to present a loading indicator, then the payment method web page
- shows an overlay on top of your page that prompts the user to focus on the popup

myButton.addEventListener('click', () => { manager.start()})
This code is intended solely for illustrative purposes. As many redirect payment methods share a common approach, it is recommended to centralize the implementation of these methods within your codebase. For a practical demonstration of how to achieve this, please refer to the guide on how to handle payment methods with redirect.
