I need to call an external API call during checkout, after the shipping step. This call will use data from the cart. When the API is called, the cart data is passed to my app, returned, and displayed in the order summary in the Billing-Step.
Thank you for replying.
I have created a custom payment method.
Now I have a third-party API for the payment process. I have to load that API to send the billing details.
and I don't how can I load that API in Payment Information.
I want to load that API when the setup Payment Information is load in checkout when we select the payment method.
