Our need is to periodically call an external API from within a Hubspot application. That API will return data in the necessary format so that Hubspot can add new contacts. using /contacts/v1/contact
External to Hubspot, we capture lead/contact data at conventions/trade shows and this data is sent to a web application, so that exhibitors of the event can login and see their leads. What we are trying to do is use your API to get this data into their Hubspot account.
Is there a way within Hubspot to call an external API, and process the response?
