For a connector you can define connection variables. These are used to replace elements of the base URL of the
connector. For example, if you have a connection variable called apiBaseUrl and the base URL of the connector is set
to https://{{apiBaseUrl}}.example.com, then the value of apiBaseUrl will be replaced in the base URL.These variables are set on each connection, along with the credentials required to authenticate with the external
system. This is very useful for embedded integrations where you are integrating with a system
where each of your End Users could have their own instance hosted on a different domain. Using connection variables, you
can use one connector and your users can seamlessly connect to their own instances.
