Name your connection. Keep in mind each connection can connect to only 1 database so include your database name in the Liked Service name. 

Click on Description and add a clear description for future users

Click the "{accountName}.east-us-2.azure" field.

Click the paste your instance name. Remember that Azure format, AWS, and Google cloud URLs are slightly different. Please review documentation for specifics.

Add your System user name responsible for Loading data.

We selected the DB name directly out of Snowflake and reviewed the ROLE to ensure it has the correct permissions "GG_DEVELOPMENT_OPPS"

Type the name of your Warehouse used for loading data. In our case we use "LOADING"

Type the role that has access all of the required permissions to perform data pipeline related functions in ADF. "LOADING"

You can select the Role help icon to drill down.

Click "Test connection". If it does not work (It never does first time), Snowflake is good about returning useful errors to help you find out what may need to be updated.
