Private Click Measurement & Attribution Reporting module for Ingestly

As of 22nd July, 2021, this module only supports Safari's Private Click Measurement. Chrome's Attribution Reporting will be supported soon.

Prerequisite

You must have your own Ingestly Endpoint. See the guide for Ingestly Endpoint.

Installation (Endpoint)

1. Create a table for this module on BigQuery

• Use a table schema in ./BigQuery/table_schema

2. Create a new logging cndition on Fastly

On Fastly console, open "Conditions" menu then add a request condition by copy-and-paste below code.

(req.url ~ "^/\.well-known/(attribution-reporting|private-click-measurement)/.*")

3. Create a new logging endpoint on Fastly

• Go to "Logging" then create a new BigQuery endpoint.
• Usually you can duplicate settings from the existing logging configuration for Ingestly Endpoint.
• Specify a table name for this module (must be matched with a table name you created as #1)
• Copy & paste a log format from ./BigQuery/log_format to the Fastly console.

Installation (Client)

In this scenario,

• "Referrer" is a news media website running Ads business. (Publisher)
• "Destination" is an E-commerce website who is a customer of "Publisher". (Advertiser)

1. Add attributes to the link tag on the Referrer side website.

On the web page of Referrer side, add attributionSourceId, attributeon and attributionDestination to a link to the Destination. If your (eferrer side) domain is report.destination, and your client is link.destination: - attributeon should be https://link.destination (same with link destination) - attributionDestination should be https://report.destination (same with your website)

<a href="https://link.destination/"

attributionSourceId="123"
attributeon="https://link.destination"
attributionDestination="https://report.destination"

attributionsourceeventid="123"
attributionreportto="https://report.destination"

>A link to the destination</a>

2. Place a pixel tag to a "conversion" page on the destination website

On the web page of Destination side, add the following pixel tag to trigger the PCM reporting scheduling event.

The PCM requires a "pixel" request for triggerring a PCM reporting. The pixel request must be redirected to a "well-known" structured URL with HTTP 302.

So, use the following pixel tag.

<script>
    (function (w, e, pd, pp) {
        var d = window[w].document,
            i = d.getElementsByTagName('script')[0],
            t = d.createElement('img');
            t.style = 'visibility:hidden;';
        t.async = true;
        t.src = 'https://' + e + '/ingestly-pixel/pcm/?trigger_data=' + pd + '&trigger_priority=' + pp;
        i.parentNode.insertBefore(t, i);
    })('self', 'example.com', '00', '00');
</script>

You need to modify at least three parameters in the last line.

Parameter	Example	Description
Target Window	self
Hostname	example.com
Trigger Data	00	A trigger event type. You need to define the type ID between 00 to 15, and the value must be 2 digit string.
Optional Priority	00	A trigger priority. PCM stores a single attribution for each trigger data, so if you want to breakdown a conversion into multiple steps, assign the priority and PCM may keep an attribution with highest priority. A value must be between 00 to 63, and must be 2 digit string.
