Epicor P21 Pricing Engine

Hi all

I was wondering if any one is using pricing engine from outside of P21?

So, in the quote/order P21 screen, instead of using the built-in pricing engine with pages/books/libraries, has anyone used an external API call to provide pricing? There are numerous companies out there that provide pricing analysis along with pricing API calls.

Please let me know as I am trying to understand if anyone else has gone down this road, what their options and pain points were as well.

Thank you
