Push Liked CMS item ID into member fields in Airtable upon click

Hi there,
I am trying to build an app where if a user likes an item and adds it to its favourites, a webhook pushes the CMS item ID into member fields in Airtable. My plan is to have certain workflows in Airtable based on what items a user likes in Airtable.
For example: If a member likes a certain city, I want to automate a workflow where they will get newsletters about the liked city.
I have the solution to automate from Airtable, but I am struggling to find a solution to get liked CMS item into the member field in airtable.
I am using Zapier for integrations, Memberstack for memberships, and Airtable for data management.
Any help would be greatly appreciated.
Thanks so much!
