Depending on the Form or Data Source Connector you want to use, you may need to set up a Connection with the external service to authenticate communication between the two platforms.
These Connections store the authorization and destination details of your target external service account, allowing you to push and pull data from them with Form or Data Source Connectors.
To add a Connection, navigate the side menu to: Data Hub > Connections

On the Connections page, click the Add Connection button at the top right or click adding a connection to choose a Connection type.

Next, you’ll need to configure or grant access by filling in the required details for the connection you add.
Some connections—such as Google—require you to click on an Authorize or Sign In button, which will open a login window for your target service account and authorize our platform to access it.
After granting access, you should be returned to the Connections page.
Then, Save your changes to store configurations and automatically verify the connection.
Now you can successfully add Form and Data source Connectors to push and pull your data from the authenticated external service.
