Configure data retrieval in REST API from GET to POST

[jnimander]

When working in a highly secure enviroment, having possibly sensitive data as a query parameter in a GET request is not allowed. (See CWE-598) I know using GraphQL eliminates this but not all client applications can easily switch to using GraphQL. It would be great if you could force DAB to use POST requests instead and use some format to pass the OData parameters in the request body.
