Amphtml: Overwriting ampdocUrl in Google Analytics/amp-analytics not working

[ryanlombardo]

Setting a custom value for ampdocUrl does not override the default value being sent to in the Google Analytics request.

By default, Google Analytics sends the AMP url and we want to change it to the canonical url.

Here's our config:

  <script type="application/json">
    {
      "vars": {
        "account": "{{Analytics.google_analytics_id}}"
      },
      "requests": {
        "pageviewWithCD27": "${pageview}&cd27=${cd27}"
      },
      "triggers": {
        "trackPageviewWithCustom": {
          "on": "visible",
          "request": "pageviewWithCD27",
          "vars": {
            "ampdocUrl": "CANONICAL_URL",
            "cd27": "amp"
          }
        }
      }
    }
  </script>

And here's the request sent to GA showing the default value still being used. (Look for the dl parameter.)

@ryanlombardo I believe you said this was working for you last week?

[ryanlombardo]

Yes, we tested it on Friday and I'm fairly certain that it was working.

Please override documentLocation variable and set it to CANONICAL_URL. We had to make the change because setting ampdocUrl to canonical Url did not make sense semantically.

[rudygalfi]

@ryanlombardo Hopefully @avimehta's suggestion helps resolve this. Please re-open if not.

[ryanlombardo]

It works! Thanks.

How to override documentLocation? I can't find anything like this on documentation or source code of the generated page.

[avimehta]

@tzkmx Does the following work?

<amp-analytics type="googleanalytics">
<script type="application/json">
{
  "vars": {
    "account": "UA-XXXXX-Y"
  },
  "triggers": {
    "trackPageviewWithDocumentLocation": {
      "on": "visible",
      "request": "pageview",
      "vars": {
        "documentLocation": "https://www.examplepetstore.com/pets.html"
      }
    }
  }
}
</script>
</amp-analytics>

[tzkmx]

Yeah, it does! Thanks a lot!
