Create an Input
First, navigate to the Connectors app and click on Add a connector.!
Next, we can input the credentials for the data connector (Postgres, MySQL, MongoDB...) that we want to connect to RestApp. This will serve as either an input (source) or an output (destination).
Confirm the data connector is active
After creating your data connector, confirm that the connection status is active by clicking the Test Connection button. Make sure that testing the connection returns green before continuing to the next step. If the connection is failing, you can always edit your data connector credentials and try again.
