Hey @bredlawskk

Monday.com offers API to interact with it.

https://api.developer.monday.com/docs

Additional information about building apps are available at https://apps.developer.monday.com/docs/intro

You can also connect your existing solution (if possible) to monday.com using third-party services like Integromat: https://www.integromat.com/en/integrations/monday

A simple answer is:

Custom designing monday.com to interact with company’s already built applications is not possible for someone without a lot of technical background

Using third-party services like Integromat lets someone build an integration between monday.com and his existing application without writing a line of code, but it requires at least basic dev skills and knowledge.
