Strict GET request restrictions are frequently the cause of seeing a 403 error with Azure API Management (APIM) when executing a SQL query containing a WHERE clause. This problem is common when creating REST APIs using Azure Functions and APIM, particularly when retrieving data from sources such as Databricks Delta Lake. In order to handle queries securely while permitting helpful SQL commands, the paper provides options for setting up APIM policies and managing SQL validation. Developers can increase **security** and **query flexibility** without running the danger of unauthorized data access by using optimized backend techniques.
