title: Can't authenticate to google webrisk api
body: <p>I am trying to authenticate to google webrisk api in python3, but I can't figure out a way to do it. This is what I have done</p>
  <ol>
  <li><p>Create a service account key from console.cloud.google.com</p>
  </li>
  <li><p>Setup an environment variable GOOGLE_APPLICATION_CREDENTIALS=&quot;path/to/keyfile.json&quot; with the pointed file containing the key downloaded from the previous step</p>
  </li>
  <li><p>In the code I wrote</p>
  </li>
  </ol>
  <pre><code>client = webrisk_v1.WebRiskServiceClient()
  request = webrisk_v1.SearchUrisRequest(
    uri = &quot;some_url&quot;,
    threat_types = [&quot;SOCIAL_ENGINEERING&quot;, &quot;MALWARE&quot;, &quot;UNWANTED SOFTWARE&quot;]
  )
  response = client.search_uris(request = request)
  </code></pre>
  <p>However, I keep getting error saying &quot;ACCESS_TOKEN_EXPIRED&quot;. What am I doing wrong/missing?</p>
