consumer key as parameter - definitions.yaml

[gftpayments]

Hi, according to https://docs.apigee.com/api-platform/istio-adapter/examples#api_key_as_query_parameter documentation, we can overwrite part of definitions.yaml configuration in httpapispec.yaml. My question is: I want to accept consumer key via parameter, not header. I know we can do it in httpapispec.yaml. But I would like to do it in definitions.yaml and make it global. Probably I will need to change this line: api_key: request.api_key | request.headers["x-api-key"] | "" but I do not know the syntax. Could someone help me? Best regards
