Register a Snowflake Host

The enhanced onboarding API is a REST API which allows users to register a Snowflake to Immuta with a single set of credentials rather than configuring an integration and creating data sources separately. Then Immuta can manage and enforce access controls on your data through that host. To manage your host, see the Manage a host reference guide.

Requirements

The following permissions and personas are used in the registration process:

  • Immuta permission: CREATE_DATA_SOURCE

  • Snowflake permissions for the user registering the host and running the script:

    • CREATE DATABASE ON ACCOUNT WITH GRANT OPTION

    • CREATE ROLE ON ACCOUNT WITH GRANT OPTION

    • CREATE USER ON ACCOUNT WITH GRANT OPTION

    • MANAGE GRANTS ON ACCOUNT WITH GRANT OPTION

    • APPLY MASKING POLICY ON ACCOUNT WITH GRANT OPTION

    • APPLY ROW ACCESS POLICY ON ACCOUNT WITH GRANT OPTION

    • REFERENCES on all tables

    • USAGE on the schema and database to register data sources

  • Snowflake permissions for the new Immuta system account that is created:

    • APPLY MASKING POLICY ON ACCOUNT

    • APPLY ROW ACCESS POLICY ON ACCOUNT

    • Additional grants associated with the IMMUTA database

Complete the following steps to register a Snowflake host:

  1. Use the /integrations/scripts/create endpoint to receive a script.

  2. Run the script in Snowflake.

  3. Use the /data/connection endpoint to finish registering your host in Immuta.

Step 1: Generate the script

POST /integrations/scripts/create

  1. Using the example request, update the <placeholder_values> with your connection details.

  2. Copy the config object to use later in the setup process.

  3. Run the request.

  4. Copy the returned script and use it in the next step.

curl -X 'POST' \
    'https://<your-immuta-url>/integrations/scripts/create' \
    -H 'accept: application/json' \
    -H 'Content-Type: application/json' \
    -H 'Authorization: <your-bearer-token>' \
    -d '{
    "type": "Snowflake",
    "autoBootstrap": false,
    "config": {
      "host": "<your-Snowflake-hostname-url>",
      "warehouse": "<your-Snowflake-warehouse>",
      "database": "<your-Snowflake-database>",
      "authenticationType": "userPassword",
      "username": "<new-Snowflake-username>",
      "password": "<new-Snowflake-password>",
      "audit": {"enabled": true},

    }
    }'

Payload parameters

AttributeDescriptionRequired

config.host string

The URL of your Snowflake account.

Yes

config.warehouse string

The default pool of compute resources the Immuta system user will use to run queries and perform other Snowflake operations.

Yes

config.database string

Name of a new empty database that the Immuta system user will manage and store metadata in.

Yes

config.username string

The new username of the system account that can act on Snowflake objects and configure the host. The system account will be created by the script in step two.

Yes

config.password string

The password of the system account that can act on Snowflake objects and configure the host. The system account will be created by the script in step two.

Yes

config.audit object

This object enables Snowflake query audit.

No

config.audit.enabled boolean

If true, Snowflake query audit is enabled. Set to true for the recommended configuration.

No

config.workspaces object

This object represents an Immuta project workspace configured for Snowflake.

No

config.workspaces.enabled boolean

If true, Snowflake project workspaces are enabled. If you use Snowflake table grants, set to false because table grants and project workspaces cannot be used together. Set to false for the recommended configuration.

No

config.impersonation object

This object enables user impersonation.

No

config.impersonation.enabled boolean

If true, user impersonation is enabled. If you use Snowflake low row access policy mode, set to false because that mode and impersonation cannot be used together.

No

config.lineage object

This object enables Snowflake lineage ingestion.

No

config.lineage.enabled boolean

If true, Snowflake lineage is enabled. Set false for the recommended configuration.

No

config.userRolePattern object

This object excludes roles and users from authorization checks.

No

config.userRolePattern.exclude array

This array is a list of roles and users to exclude from authorization checks. The roles and users will not have policies applied to them when querying Immuta protected Snowflake tables.

No

Step 2: Run the script in Snowflake

Using your generated script, run it in your Snowflake environment as a user with the permissions listed in the requirements section.

The script will create an Immuta system user that will authenticate using the credentials you specified in the script generation. This new system user will have the permissions listed above. Additionally, the script will create the database you specified in the earlier step.

Step 3: Create the host in Immuta

POST /data/connection

Using the tabs below, copy the request and update the <placeholder_values> with your connection details. The connection details here should match the ones used when generating the script, and the payload from the script generation should be pasted exactly into nativeIntegration. Then submit the request.

Find descriptions of the editable attributes in the table below and of the full payload in the Host registration payloads reference guide. The recommended setting values are included in the example.

Test run

Opt to test and validate the create connection payload using a dry run:

POST /data/connection/test

    'https://<your-immuta-url>/data/connection' \
    -H 'accept: application/json' \
    -H 'Content-Type: application/json' \
    -H 'Authorization: <your-bearer-token>' \
