I think you'll want to do one of: 1. use Make.com's data store feature 2. save the variables to your Google sheet, associated with the user 3. return the variables in your response to be sent in the payload of the second request by your assistant 4. have your scenario call itself with the variables in the payload, or have a second scenario which is called with this data If none of that helps you might be better off asking in a Make.com-specific support forum, rather than Vapi 🤷‍♂️ (though there's a lot of no-coders here who may want to weigh in)
