It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.
With the lack of details, any suggestion we might have for how you could accomplish this yourself would just be a shot in the dark.
What you should do is ask the developer/vendor of the e-commerce application.
