export GOOGLE_APPLICATION_CREDENTIALS='key.json'

Note: If it doesn’t work, then provide the complete file path.

"q": ["How are you feeling today"],
"target": "hi"
}

Use the curl command to hit the Translation API endpoint

$ curl -X POST -H "Authorization: Bearer "$(gcloud auth application-default print-access-token) -H "Content-Type: application/json; charset=utf-8" -d @request.json https://translation.googleapis.com/language/translate/v2

You can test the same using postman as well.

Congratulations :) Now you successfully learned how to create and use the Google Cloud Translation API service.
