Missing Web Events due to Ad Blockers and How to Handle It

Hi there Amplitude Community!When using Amplitude Web SDKs, it is possible that some users’ events are not ingested into Amplitude due to ad blockers. Currently, we are not able to estimate the percentage of events that do not get ingested as we do not have the data to support it. While we do not offer official support for circumventing ad-blockers, our Engineering Team has provided a workaround - run a reverse proxy through your own domain. Please note that it is best that this process is done by an Engineer or a Developer as this is a technical workaround.Details on what a proxy service is and how to use it in this setting can be found here:https://www.docs.developers.amplitude.com/analytics/domain-proxy/Hope this helps! ----- please give this post a thumb-up if you find it helpful! This will help us know what content we should publish in the future :) -----Amplitude Team

Instrumenting the Duration Event Property

Media customers that are interested in tracking the amount of time users spend on their products would be interested in instrumenting a property that measures the duration between two events. With this property, users can then measure various items such as Average Property Value, Median Property Value, or use the duration values in complex formulas in our Event Segmentation: Formulas chart.  To track duration, you would need to capture the timestamp of a Start Event and timestamp of an End Event, calculate the difference between the two timestamps, and then pass in the duration as an event property for the End Event. In our demo account this End Event is called Played Song, and here is an example chart: https://analytics.amplitude.com/demo/chart/new/snewb09  As an example for Page View events, let's say you have a Start Event = 'Viewed Home Page' and an End Event = 'Clicked Signup'. When the user fires the 'Viewed Home Page' event, you can create a variable in your code called first_ti

Cross Domain Tracking with GTM and Flutter + UTM data

Hi all, We have installed Amplitude on our Webflow website example.com via GTM. We have installed Amplitude on our Flutter web-app App.example.com via the Flutter SDK. The get UTM info, our dev team added the UTM tracking option to the Javascript script in the index.html file. They enabled the following options:includeFbclid includeGclid includeReferrer includeUtmWe can verify the UTM $identify event is now being fired. One important reason for us to use Amplitude is the ability to track visitors & users across our website and web-app. Example scenario: a visitor visits Example.com and clicks the button "Start for Free". This brings them to the web-app App.example.com where they create an account and start using our app. At the moment, the website and web-app return very different IDs for the same person on the website vs. web-app.  From documentation & other community posts, I learned that when we pass the device_id when people click from our website example.com to our web app

Event not showing up when redirecting user to an external page on button click

We have a button on our website. Clicking on this button will send users to an external page (a page with a different domain) in the same tab. We want to register click event on this button.My code is something like this:const handleClick = () => { track(EVENT_NAME) window.location.href = EXTERNAL_URL}In this case, we are not seeing the event on amplitude.I am assuming this is because we are navigating away from website before amplitude has enough time to send the event.We tried adding `await` to the amplitude `track` event which works but it is resulting in a slight delay which is not a good user experience.Does anyone have any solution for this? This looks like a common use case.

[Amplitude] Page Viewed Default Parameters

Hi Community!I’m new to Amplitude Analytics, and I’m currently using it to track events in my web page.When I entered into different pages, Amplitude Analytics will automatically log the [Amplitude] Page Viewed event in the Amplitude debugger, with some parameters. Here are the two questions I want to ask:One of the parameter is User Id, when this event triggered in my web page, this id will defaultly set to undefined, is there any way for me to change the User-Id here to my custom user-id? Since each user in my web page will be assigned an unique id, is there anyway to show the id in the User Id also?   For the referrer in the Event Properties, why is it that whenever I go to any page it shows the url of home? Or did I misunderstand the referrer? Because I want it to show me the url of the current page when I go to a different page, but why does the referrer stay home? I'd appreciate it if someone could explain it to me! Thanks! ​​​​

Can't see option to merge / transform events

Hi there,I’m looking to consolidate some events and according to this help page I should be able to see a ‘Transform’ option after I select the events to merge (as shown in pic) yet sadly its not available. I believe the ‘Transform’ option feature is available on all plans. Can anyone tell me where I’m going wrong please?Thanks in advance, Tom

Device type groups as property group

Hello, we’re trying to get a consistent and easy to use view of device types, but not at the level that Amplitude uses in it’s event. Ideally we would like to see a breakdown of Desktop (Device type = Mac or Windows) vs Mobile (all others). I tried to do this via Property Groups, however I noticed that Device Type and Device Family do not show up in the dropdown when I search for them. We would like to group by this property in charts instead of having to make two separate events, one for desktop and one for mobile. Thanks!

Trying to add a custom value on user lookup

I’m trying to pull in custom value (it’s a property called “name” that we created) on the user lookup.The goal: we’d like to view the User-Lookup sorted by “username” on our app, rather than the user ID (which is a string of long numbers)Any ideas?

Integrating Subscription Data from App Store & Google Play

I don’t understand from this document and discussion whether Amplitude can automatically retrieve data about my subscriptions from the App Store and Google Play if I add the iTunes Connect Shared Secret. Is this possible, or do I need to manually send this data from my server, which is also notified by Apple and Google about renewals, cancellations, and refunds?

How to see how many users open an app daily

Say I have 100 users. I want to know, for each user, whether they opened the app on day 1, 2, 3, etc.I don’t think I am looking for retention, but as an example, my current retention at day 30 is 40%. But this doesn’t really tell me whether the users in that 60% portion still might be using the app, just very sporadically, even on day 40, or even 100. Right? The nature of my app doesn’t really require constant usage.

Analytics for multi-tenant application

I run a multi-tenant application. Each organization represented in my database has its own deployment. I’d like to be able to easily isolate all events and user sessions per organization. What is the best practice for enabling this?I’m considering the following routes to accomplish this:A single Amplitude Project for all tenant deployments, then tagging every user and event with a tenantID. A distinct Amplitude Project for each tenant deployment.

Compare conversion difference between 2 flows

Hello,I have set up a chart to compare the conversion difference between users:who started with (1A) and then (2) = flow 1A2VS.who started with (1B) and then (2) = flow 1B2as follows: I wonder if this is a correct setup The user U1 who started with view-search-results-page had to go to checkout page and triggered view-checkout-page prior to end the journey with purchase.  The user U2 who started with view-checkout-page went back to view-search-results-page then view-checkout-page and purchase. The question is: can we be sure that U1 is only counted in flow 1A2, and U2 is only counted in flow 1B2?Thank you so much!

User ID as a User Property in GTM source

Hi,I’m setting up Google Tag Manager as the source for Amplitude events. The event is streaming, but without the User ID as a User Property.I have created three tags:All Pages Initialize All Pages Set User ID Track Event (track) with the needed triggerIf I add the User ID to the Event Properties of the Track Event tag, the correct User ID appears in the Event Properties in Amplitude. However, I need it to be in the User Property to connect this event to all other events of this user.According to the manual, since my event is an onboarding event and I need to initialize the User ID at a later time, I have to use setUserId. That's exactly what I need, but it didn’t help.

Best practices for distinguishing events from different products?

Hi, I'm working for an edtech company. So far we had only one product that runs across web & mobile. In order to easily filter or segment events that happen in different platforms, we could use the Platform user property built into Amplitude. Now we are adding a second product which will launch in web first. I’m now wondering what we should do in order to be able to easily filter and segment events happening in one product. Users on both products will now have ‘Web’ as Platform.My initial thought was to just use the data source and use that to filter. But I just checked and found that you cannot filter by source when creating a report.So my question: What best practices do you know for this? How have you solved this problem?I know adding suffixes to the event names of the new product could be an option, but I’m wondering if there’s a better solution (a naming convention would be great to quickly identify in which product an event occurs, but this would really also require us to ret

Event Tracking & Dashboarding Issue

 Hi there,I'm having some issues with our amplitude event tracking & dashboards. Our team has recently set up all our app events to send to Amplitude. When we look at the Amplitude events on their own , for example "subscription_started" or "trial_activated", the data coming into Amplitude is correct and lines up when we Q/A. However, as soon as we try and create a funnel or dashboard to visualize the movement of data through events, for some reason the data doesn't seem to report accurately or in some cases, the events, like "subscription_started", won't fire at all.We've been trying to figure out this issue for almost a month now and it's been preventing us from scaling with Amplitude.Before April 3rd, multiple users could possibly be associated with the same device ID. With our understanding, this should not affect the funnels/dashboards. Since April 3rd, we've updated the device ID to be unique across the users, but it still doesn't seem to have fixed the discrepancy. For now,

Assistance Needed: Query Regarding Amplitude API for User Activity Tracking

I am writing to seek assistance with regards to utilizing the Amplitude API for tracking user activity within our application.Our team is currently working on implementing a feature that requires tracking user engagement and activity patterns. Specifically, we need to track users who log in to our app consecutively for 15 days and spend a minimum of 10 minutes each day within the same user account.After reviewing the documentation provided by Amplitude, I believe that the Event Segmentation API or a similar API endpoint might be suitable for our requirements. However, I would greatly appreciate your guidance on which specific API endpoints and parameters would be most appropriate for achieving this goal.Could you please advise on:1. Which API endpoints and parameters should we use to track user logins and session durations?2. How can we set up the query to identify users who meet the specified criteria of logging in consecutively for 15 days and spending a minimum of 10 minutes each da

BigQuery - User properties ingested through bigquery don't sync totally or veeerrry slowly

Hi ! I setup yesterday (more than 15 hours ago) a connection between bigquery and amplitude. I triggered a full sync on 24k users, ingesting 3 distinct user properties for those users. It seems to work BUT after 15 hours or so I see only 4.3k users have been updated (see screenshot below) If I look via “segmentation” chart I find a different result  Is there something around how I look at the data and actually everything is already ingested and updated ? Or is that normal that it takes so long to update the user properties? Or is there some mechanism that explains that?  Thanks!
