Get the affiliate_id from the URL

Hi, I put my chatbot inside a wordpress website. After asking the user information, the data are save to airtable. The chatbot works fine.
But I want to get the 'affiliate_id' and 'transaction_id' as well if the visitor comes from affiliate url.
From what I understand the data can be capture if they are inside the chatbot only.

Example link: https://example.com?affiliate_id=2&transaction_id=33682vb3

I use everflow to track the affiliate. Is it possible?

Thank you in advance
