Categories Data

This connector is based on the Snowflake SQL REST API. Snowflake’s Data Cloud is powered by an advanced data platform provided as a self-managed service. Snowflake enables data storage, processing, and analytic solutions that are faster, easier to use, and far more flexible than traditional offerings. The connector uses the Snowflake REST API V2 to submit synchronous and asynchronous queries and retrieve corresponding results.

How to get credentials

Set up Microsoft Entra ID authentication for Snowflake by following these steps:

  1. In Step 1: Configure the OAuth Resource in Microsoft Entra ID, 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 Microsoft Entra ID, 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 Microsoft Entra ID Information for Snowflake entirely.
  6. Copy and paste the text below into your Snowflake worksheet, which is where you execute your queries in Snowflake. Before you execute the query, make sure you make the following replacements so that your query succeeds. A. In Microsoft Azure, go to your Snowflake OAuth Resource app and click on Endpoints. B. 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. C. 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.
    D. Replace the Audience List URL in line 7 with Application ID URI from Step 1. Keep the quotation marks.
    E. 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.
    F. Make sure you've set your role as ACCOUNTADMIN. Now you can execute your query.

Known issues and limitations

  1. If you get a 500 response when creating a new connection, that is a transient error. Please wait a few minutes and try again.
  2. If you get a 401 response and your Host field in Step 1 follows this format "orgname-accountname," replace the Host field with your "locator" URL.
  3. The connector may time out with large query results.

FAQ

  1. How can the connector be used within Power Apps? Currently, Power Apps does not support dynamic schema. You can still use the connector from Power Apps by calling a flow from the app instead of directly from an app.
