Hello guys, i’m new to shopware and i’m having some problems.
I have a submit button and I want to change the action url but whatever url I put there it gives me a controller error, and i don’t know were is the controller to modify it.
Can someone help?

Hey bogdanvoodo,
do you want to call a controller from the backend or from the frontend?
Maybe you can give us a explicit example of what you want to do 😉
Regards,
Simon 😉

I managed to put a link to a button to go to an external page with a payment method, but i dont know how to deliver the amount from the site to the external page.
And another think, I dont know how to make a new controller

If you have no idea - my advise is to use existing payment-method plugins.
You are dealing with serious securtiy issues and must have a decent knowledge about shopware’s structure to implement a secure shopware payment plugin!
