[support] Help with payment solution development(Call back url)

[Mutuku Ndeti]

I am developing(rather adapting uc_echecknet) for a local payment
solution. The payment solution provider posts the results back to my
shopping cart to a callback url.

I am able to post data to the provider...but I am not sure which url
to give the provider. Is there a stardard one or do i need to create
one with the module? Any direction on how to do this?

Thanks
