Snowflake connector is based on the Snowflake SQL REST API. Snowflake enables data storage, processing, and analytic solutions that are faster, easier to use, and more flexible than traditional offerings. The connector uses the Snowflake REST API V2 to submit synchronous and asynchronous queries and retrieve corresponding results.

Prerequisites

  • Users must have Microsoft Entra ID for the external authentication.
  • Users must have a premium Power Apps license.
  • Users must have Snowflake account.

How to get your credentials

Set up Azure AD authentication for Snowflake by following these steps:

  1. In Step 1: Configure the OAuth Resource in Azure AD, follow steps 1-10 and define the scope as SESSION:ROLE-ANY by following these instructions.
  2. In Step 2: Create an OAuth Client in Azure AD, follow steps 1-13.
  3. Navigate to Authentication -> Platform configurations -> Add a platform -> Add "https://global.consent.azure-apim.net/redirect" -> Click Save. Ensure that the redirect URL is set in the Snowflake OAuth Client and not the Snowflake OAuth Resource.
  4. Go to the resource created in Step 1 and go to Expose an API -> Add a client application -> Add your APPLICATION_CLIENT_ID from earlier in step 3 above -> Click Save
  5. Follow Step 3: Collect Azure AD Information for Snowflake entirely.
  6. If you have already established a connection using the Snowflake certified connector, follow the steps in section Update existing security integration in Snowflake. If you are establishing a new connection, follow the steps in section Create new security integration in Snowflake. Make sure you've set your role as ACCOUNTADMIN before executing the query.

Create new security integration in Snowflake

  1. In Microsoft Azure, go to your Snowflake OAuth Resource app and click on Endpoints.

  2. To get the AZURE_AD_ISSUER in line 5, copy the link in the Federation metadata document field and open the link in a new tab. Copy the entityID link which should something look like this: https://sts.windows.net/90288a9b-97df-4c6d-b025-95713f21cef9/. Paste it into the query and make sure you have a / before the last quotation mark and that you keep the quotation marks.

  3. To get the Keys URL in line 6, copy the link in the OpenID Connect metadata document field and open the link in a new tab. Copy the jwks_uri which should look something like this: https://login.microsoftonline.com/90288a9b-97df-4c6d-b025-95713f21cef9/discovery/v2.0/keys. Paste it into the query and make sure you keep the quotation marks.

  4. Replace the Audience List URL in line 7 with Application ID URI from Step 1. Keep the quotation marks.

  5. If your Snowflake account uses the same email address as your Microsoft Azure account, then replace login_name in line 9 with email_address. If not, keep it as is and do not type in your login name. Keep the quotation marks.

CREATE SECURITY INTEGRATION <integration name>
type = external_oauth
enabled = true
external_oauth_type = azure
external_oauth_issuer = '<AZURE_AD_ISSUER>'

external_oauth_token_user_mapping_claim = 'upn'

Update existing security integration in Snowflake

ALTER SECURITY INTEGRATION  <existing integration name>
set external_oauth_audience_list = ('<existing power bi audience list url>', '< Application ID URI from Step 1>')

Using the credentials

While creating the connection in power platform, use the credentials as shown in below snapshot.

  1. Client Id: Snowflake OAuth Client ID from registered Client app in Azure
  2. Client Secret: Snowflake OAuth Client secret from registered Client app in Azure
  3. Resource URL: Application ID URI from registered Resource app in Azure
