How to get the API Connector to initialize when providing a Stripe ID as a parameter

Hi Everyone.

I am using stripe through the API connector, and I the connected account will change based on the user - but I am unable to initialize the api call because the key value is empty. What do I put in the key value so that I can initialize the call and change the value with each different user’s account id?

Looks like it would be the connected stripe account id
