Create a Snowflake connection
You need to know the server and database name to create a Snowflake connection. You must have access credentials to access data stored on a Snowflake database. Once you have created a connection, you can select data from the available tables and then load that data into your app.
In Qlik Sense, you connect to a Snowflake database through the Add data dialog or the Data load editor.
Database properties
Database property | Description | Required |
---|---|---|
Direct Gateway |
This field will only appear if you selected the "via Direct Access gateway" data connection. Select the data gateway through which you need to connect to your data source. Information noteUsers that need to leverage gateway-enabled data connections must have the Can Consume Data permission for the space in which the gateway resides.

Snowflake configuration for OAuth
Your Snowflake database must be configured to use OAuth. The process is described in Snowflake documentation:
-
Configure Snowflake OAuth for Custom Clients
Information noteProof Key for Code Exchange (PKCE), as recommended by Snowflake, is enabled.
When configuring the OAuth authorization server, the redirect_uri must be set to: https://connector.qlik.com/auth/oauth/v2.htm
Key pairing
Qlik Cloud Government does not support Snowflake key pairing.

Account properties
Credentials
Credentials are used to prove that a user is allowed to access the data in a connection.
There are two types of credentials that can be used when making a connection in Qlik Sense SaaS. If you leave the User defined credentials check box deselected, then only one set of credentials will be used for the connection. These credentials belong to the connection and will be used by anyone who can access it. For example, if the connection is in a shared space, every user in the space will be able to use these credentials. This one-to-one mapping is the default setting.
If you select User defined credentials, then every user who wants to access this connection will need to input their own credentials before selecting tables or loading data. These credentials belong to a user, not a connection. User defined credentials can be saved and used in multiple connections of the same connector type.
In the Data load editor, you can click the underneath the connection to edit your credentials. In spaces or Data manager, you can edit credentials by right-clicking on the connection and selecting Edit Credentials.
See which authentication type applies on each connector's page.
