问题
When I create a new Logic App and choose, for example, "SFTP file is added or modified" I am prompted to add the connection information. I have already created an API connection to my SFTP server. How to choose this existing connection instead of creating a new one in Designer? Or do I have to switch to Code View in order to use an existing connection?
Update: I tried in code view to copy over my connections ( the "$connections" element from another Logic App) and go this error:
Operation failed: The template validation failed: 'The template parameters '$connections' are not valid; they are not present in the original template and can therefore not be provided at execution time. The only supported parameters for this template are ''.'.

The answer is that the new Logic App has to be in the same region as the existing API Connection.
