Claim Widget - Return minting address and confirmation

Is there an option/solution to be able to return the minting address and success confirmation to the webapp hosting the widget?

We will using the Claim Widget (buy now) to complete a minting transaction but need confirmation of a successful transaction in the app along with the minting address.

A solution integrated in the widget would be great but if there is an alternative (api, etc.) we would be open to that as well.

Thank you for your help!
