I'm trying to integrate the Redys payment gateway into a web created in Angular 4 and backend in Node.js.
The backend I have managed to work using the package, redsys-polite .
The problem is that I do not know how to integrate it with the frontend because the backend automatically redirects me to the Redys page and when the user finishes or cancels the purchase redirects me to a backend route not from the frontend.
Thank you.
