Some connectors such as:

1. Apple App Store
2. Delighted
3. SAP Concur
4. ServiceNow
5. Twilio

required config parameters to create the connector include personal information (such as such as username, password, api keys)  instead of only  classic ones such as schema and table name.  It would be desirable that fivetran only requires schema/table config parameters to be able to create the connector, and then to require personal information for the authorization.

If fivetran only requires schema/table config parameters, the design for connector integrations would be the same for all connectors, instead of having some connectors where parameters should be defined by the customer, which  implies a different configuration process for these connector.
