Using online code generator, it appears that collectionformat == “multi” is not respected.
*Online Swagger Codegen Version: *2.2.3 *Was this issue fixed in version 2.3.0? Reference Link - * https://github.com/swagger-api/swagger-codegen/pull/6199 If so, can the online generator be pushed to a later version? 2.3.0 appears to have dropped in December and my work proxy will not allow me to download the maven jar file needed to take swagger codegen offline… Generated API call, note Dictionary will never permit the repeating of the key of a key-value pair, and multi requires the repeat of the key in the query string. public ApiResponse< List<ElementVersion> > GetLatestElementVersionsWithHttpInfo (string pageLimit = null, string pageStart = null, List<string> id =
