Hi,
I'm not familiar with these "Google Cloud Storage APIs".
From what I read:
https://cloud.google.com/storage/docs/apisIndeed, you could try the Java interface that should work with Genero:
https://googleapis.dev/java/google-cloud-storage/latest/index.htmlThe other option is the REST apis with JSON or XML:
https://cloud.google.com/storage/docs/json_apihttps://cloud.google.com/storage/docs/xml-api/overviewAs Google does not provide a service description (WSDL or openapi) we cannot automatically generate the client stubs.
You will need implement the client functions with GWS low level apis. That can be done with your 3.10 version.
You might mis a PATCH verb for some apis. PATCH is only available with V4.
Depending on the number of Google apis you use that could be quite fast as Google provide request/response samples.
About the OAuth authentication you have a simple in $FGLDIR/web_utilities/services/openid-connect.
Maybe you can contact our professional services and see if they can help you.
Best regards,
Sisa.
