responseParameters property
A key-value map specifying response parameters that are passed to the method response from the backend. The key is a method response header parameter name and the mapped value is an integration response header value, a static value enclosed within a pair of single quotes, or a JSON expression from the integration response body. The mapping key must match the pattern of method.response.header.{name}, where name is a valid and unique header name. The mapped non-static value must match the pattern of integration.response.header.{name} or integration.response.body.{JSON-expression}, where name is a valid and unique response header name and JSON-expression is a valid JSON expression without the $ prefix.
Implementation
final Map<String, String>? responseParameters;
