hi! I don't know a huge amount building Stripe Apps and my team's expert on them is not around today.
As far as I know though it doesn't really work that way, you don't just get a raw API key for the account that installed the app. When they install the app, you get access to the permissions that you specified in your manifest file, and you'd directly call the Stripe API using your own API key and the stripe_account header set to the ID of the account that installed the app(https://stripe.com/docs/stripe-apps/build-backend#authenticate-requests)

I don't think you can do something like turn over a key to a third party like Fivetran and have them ingest data that way, instead the way it works is you call the API and get whatever information you need in terms of actual API objects and then would need to do things with that
