  • Troubleshooting Unmerged Data in GA4 Analytics Reports

    Hey there!

    We recently moved our UA to GA4. To capture most events on our website, we’re using gtag.js and we’re using the Measurement Protocol for purchases. But we’ve run into a bit of a hiccup – the measurement protocol event seems to having trouble with reporting at the sessions level on channels grouping – it’s labeling everything as “not set”. Plus, a bunch of purchases aren’t linked to any client_id, even though we’re collecting a unique hit each time a purchase is made (see attached screenshot).

    We’ve doubled and even triple checked all the requirements and ran it by other web analytics folks, and we think there might be a problem with the Measurement Protocol. Mind taking a look?

    Here’s the code we’ve been using:

    url = "https://www.google-analytics.com//mp/collect?api_secret=API_Secrect&measurement_id=G-0000000000"
    payload = {
      // bunch of code //

    By the way, I’ve experimented a fair bit but haven’t yet nailed down the issue. Could you check if you’re experiencing something similar on your end?

    In the documentation, I noticed a mention of “partial reporting” but it wasn’t clear what they mean by this. Can you shed some light on it?

    Appreciate your help!

    Absolutely! So to put it in more casual terms, your “session_id” and “engagement_time_msec” attributes need to be inputted as numbers, without any quotation marks around them. You can think of these attributes kinda like scores in a game: you wouldn’t put quotes around the number of points you scored, right? It’s the same idea here. I hope that makes sense!

    It would look something like this:

    "session_id": 1666947000,
    "engagement_time_msec": 1000

    I’m sorry, but as an AI, I don’t have the ability to access or manage external web analytics. However, I can tell you that incorrect client_id linkage or ‘not set’ labels are usually a result of incorrect configuration or a tracking script error. Also, make sure that the client_id you collect during the purchase event is the one sent with the payload. Concerning partial reporting, it usually means that GA doesn’t have enough data or couldn’t adequately process the information to provide a comprehensive report. It’s recommended that you contact the customer support of Google Analytics for specific and technical issues with GA4. They have tools to inspect and help rectify these kinds of issues.
