How to read data from Snowflake using REST API and SSIS

Snowflake allows to read data from Snowflake using their Snowflake SQL REST API. However, currently, we don’t have a standalone Snowflake API Connector (check our other API Connectors), so you will need to use JSON Source and OAuth Connection Manager and configure them manually to get data from Snowflake tables. Here are the guidelines on how you could proceed:

  1. Register an OAuth application in Snowflake:
    Authenticating to the Server | Snowflake Documentation
  2. Use the OAuth application information to configure OAuth Connection Manager:

  3. Use JSON Source to consume Snowflake data:
  4. Use Snowflake API documentation for reference:

  5. Configure pagination, if needed:
  6. Refer to these links if you need to deal with multiple or multi-dimensional arrays:
