How can it be implemented that information about electronic auctions enters the Crm system?

Question

ERP

We are developing a system. We will sell it to clients.
We would like to be able to automatically receive information about new ongoing auctions and display this information on our CRM system.
how can this be implemented?
Maybe there is some kind of integration tool with all electronic trading?
Or just do an automatic search on certain sites?
