How to send data to form or even a document

Hello, there probably is a way how to use data stored inside Infinity – either with automations or Zapier or Webhooks or API, I hope :wink: Let me explain a use case:
We have a database of contacts stored in one Folder (Business name, Address, emails, phones etc.) and everytime we agree on a deal with partner, it would be really great if I can click a button or so and that wil automaticaly fill in the blanks in (infinity) Form or – even better – send the data to something like Google sheets / doc to particular part/field of a document.
This will save a lot time while creating a /legal) contract/s, and when creating invoices, as you may imagine.
Any suggestions please?
