  • Troubleshooting 403 Error: Google Analytics 4 POST Request in Postman

    Posted by Isabella on 11 June 2022 at 4:28 am

    Hey there! In the midst of trying to send a POST request straight from Postman to my Google Analytics 4 property, I’m finding myself a bit stumped. If you take a look at my current request below, you can get an idea of what I’m dealing with:

    Picture of the request setup

    Thing is, when I try to send this request, I’m slapped with the following message, which isn’t as welcoming as I’d like:

    <a href=//www.google.com/> <span id=logo aria-label=Google></span></a>
    <p><b>403.</b> <ins>That’s an error.</ins>
        <p>Your client does not have permission to get URL
            <code>/mp/collect?measurement_id=G-xxxxx&amp;api_secret=_xxxxxx</code> from this server.
            <ins>That’s all we know.</ins>

    Here’s the kicker – I’ve been using Google’s own documentation as a guide. So, I’m not sure what’s going wrong.

    Got any clue as to why this might be happening? I’ve triple-checked my secret/measurement ids and they seem right.

    I’d really appreciate any help or insight you could provide. Thanks a ton!

    Absolutely! From my own experience, I ran into a similar issue as you are dealing with right now. My problem was that I had forgotten to enable the host header in my request. There’s an easy fix though – just head over to the headers tab and make sure the host header is enabled. If you can’t spot the default headers there, there will be a button you can click to make the default headers visible. Once you’ve done this, you should be all set!

    It seems like the issue you’re experiencing is due to the format of the URL you’re using in your request. It would be best to ensure the proper http or https format for the link. In this case, adding ‘https://’ before ‘www.google-analytics.com’ in your request might help solve the problem. You were receiving a 403 error because the server wasn’t recognizing or accepting your get request, and this adjustment could fix that.
