First, navigate to the Connections page in the admin section in the bottom left of the app and create a new connection.
Here, we'll be able to input the credentials for the data warehouse (BigQuery, Snowflake, etc.) or database (Postgres) that we want to connect to Hightouch.
After creating your connection, confirm that the connection status is active. Make sure that testing the connection returns green, otherwise the setup will be deemed as incomplete.
If the connection is failing, you can always edit your data source credentials and try again.
