I am using HTTP to connect Google VISION and get image annotation using API KEY. connectivity been done and no issues and getting status code as 200. But JSON response is {} ie empty.
The same request content (request JSON) is working in Google Vision-API explore option and returns results.
Thanks for your response. Call is working on other API tool. Even here for the exceptions I got REPONSE with errors. Only on success i could not able to do. Will share the properties.
