google cloud datastore - I get a 401 error when accessing GCD via a URL -

-

i have tried access following url when typed browser message:

"not found"

when use in talend rest component error message:

401 error.

https://www.googleapis.com/datastore/v1beta2/datasets/my-project/runquery?key=aizasyca_j4wyyen-3q0nzwncmcoqcrrw17ec1y

an idea?

all cloud datastore api methods expect post requests. that's why error when access url via browser.

the 401 error because need provide credentials access cloud datastore api. can find more information client libraries on cloud datastore getting started page or google apis client libraries page.
