Setup tests

Fivetran performs the following Azure Functions connection tests:

• The Validate Secrets test checks if you have entered the secrets in a valid JSON format.
• The Private Link connectivity test checks if we can connect to your Azure function using Private Link.

  IMPORTANT: To connect to Azure Function using Private Link, you must be on the Business Critical Plan. We skip this test if you are not on the Business Critical Plan.

• The Function Connection test checks if we can connect to your Azure Function and if the function’s response format is correct.

IMPORTANT: The setup tests may timeout if your function’s response size is more than 500 megabytes (MB). In the setup tests request, Fivetran passes the setup_test field as true; and your function must return a lightweight JSON object with the hasMore field as false, not exceeding 500 MB in size. The 500 MB size limitation is only applicable to the setup tests and not for your syncs.
