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

X Axis parameterization

Hello. I have a problem with X Axis customization in Segmentation Chart. For Retention chart it’s easy to set X Axis values to: Week 0 / 1 / 2 / 3 / 4 etc… For Segmentation Chart i have the X Axis customed by User segmentation (I’ve filtered users by the date of their account creation per weeks like 03-09 July / 10 - 17 July etc… and that is what i have on my X Axis). Is there any chance to custom it per days / weeks / months instead of dates for example?

Is there a way to know programmatically the event names that are plotted with only a chart URL?

I need to programmatically access the event names that are in a chart that has been made with the UI. I’ve seen that the REST API for existing chart was not giving the event types in the response, is there any workaround to do this?

Cloudflare Workers SDK

I need to send events from a Cloudflare Workers environment, which doesn’t support the Node SDK due to the lack of HTTP and HTTPS modules (it only has Fetch). Digging in the source, it looks like I may be able to wrap the Node SDK and provide an alternate transport. Just wanted to see if anyone else has done this already.

GTM Amplitude Template Not Working

Hello,We’re trying to move away from Custom HTML tags to the Amplitude Analytics Web SDK Template, which should be straight forward however the tags are not firing at all, despite conditions being met. Any ideas on what the issue might be? Custom HTML tags with the exact same rules work just fine, so it must be an issue within the template. There are no console errors.

Moving event to inactive is having no effect - help please!

Hi everyone!We recently realized that our DAU (active users) numbers were spiking weirdly and figured out it was due to an event we made to related to push notifications.Following amplitude’s advice, we made the event inactive. According to documentation, “When you change an event's activity status from active to inactive, Amplitude will apply that change immediately and retroactively, so you should expect to see changes in your historical data.”However, it’s been several hours and nothing has changed - the event still appears in user paths still show this event and the charts still have the spikes.  I have confirmed the event is truly marked as inactive.When we have made events inactive or blocked in the past, they truly have been “purged” immediately. This time not…Has anyone had this experience? Is there now some sort of time queue that makes such a change to be NOT immediate?  Thanks!!Sara at Pao App

Drop filter based on insert_id

Hello,I would like to ask if it’s possible to drop some events based on their insert_id using the drop filters?We are using s3 import to ingest the data with a unique insert_id that we create outside of Amplitude. We then map the insert_id to Amplitude insert_id field in the Additional Properties at the Configure Converter step. We now want to drop some specific events and the only way to identify those events is the insert_id. We’ve tried to use drop filters but the insert_id is not showing in the options of properties.Any ideas would be much appreciated!Thank you!

Amplitude Downtime

Environment:We use three parts of the system: web, backend, and frontend.To communicate with amplitude we use amplitude-js/8.18.5 SDK for the web part and the backend and frontend - we use HTTP V2 API.Sometimes we observe an issue with custom user properties that we created on the web part. The web part is only the one part that creates and changes these custom user properties. Neither the backend nor frontend part do not set or changes these properties. Then, we expect that all these user properties should be applied to all other events from other parts of the system. The user_id user property is the same for all events from all the parts of the system. However, we have users who do not have our custom properties applied on the very first part of our system (web). After some amount of events for these users from other parts of the system these custom properties appear again for events. Almost all of the users who faced this issue were on September 19 when we saw a huge degradation acr

Can a unique user show up as multiple, when grouped

If I have a simple segmentation, where I look at “Any Active Event”, measured as “Uniques”, and Group Segment by a user property that have changed during the period.E.g. assume I only had 1 single user in my system, and one of the user properties changed during the month (From A to B). Would that single user show up as 1 user with user property A, and another user with user property B, during the same month?Or would my 1 user, only show up, with the last user property.. (B)?

Old default userId still eppearing for users

We have an anomaly in our Amplitude events that users appear with an old userID which was  present in the old version created at the initialisation phase as this:amplitudeInit(amplitudeApiKey, 'Amplitude for admin-tool', { minIdLength: 1 });Later we changed the initialization by removing the  “Amplitude for admin-tool” string and set the userId to `undefined`  for default and also used the setUserId method after login to set the actual user id.amplitudeInit(amplitudeApiKey, undefined, { minIdLength: 1 }); The problem is that we are still getting events occasionally with the userId of “Amplitude for admin-tool” string. We would like to stop their browser from sending this outdated ID and associate these users to have their actual userID set by setUserId or simply.

Get 400 error using GTM

Hi there!I have set up event tracking using GTM Amplitude Analytics Browser SDK for my DEV environment. And it works well.But then i imported all tags to another GTM container which is connected to my PREPROD environment. And i set up the correct API key for the project. But i don’t get events in the User look-up. In the ingestion debugger, i see 400 errors, but tracking tags work well - i see correct events in the Amplitude Chrome extension. What is the reason? Why do i get 400 errors?

Unique event VS Total events when using a filter

Hi everyone, I think I understand the difference between total events and unique events, but I’m wondering how it’s handled if I use filter on these events. Let’s take an example with a “form submitted” event than has a type property (demo or free trial). If I look for unique event “form submitted”, all visitors who submitted a form would be displayed once. Some of them might have submitted a free trial, some others a demo and some both. Now let’s say I want to filter this by demo. I’m concerned I might miss some visitors, for instance the ones who first submitted a free trial, and then a demo, as they indeed already have a form submit event. All in all, I’m wondering how the filters are impacting unique VS Total events. I’m not sure my description is very clear but let me know if you have questions. Many thanks, Joss

Not able to set custom user properties with "Identify"

Hi there,We’re running into issues on what should be a pretty basic task of creating a new user property. We use the `set` method of the `Identify` call to create and set a new user property, but the property won’t show up on the user’s profile in Amplitude, even after triggering followup events. We’re able to update an existing default user property’s value (e.g.: “Language”), but can’t create a new user property. We even tried creating the user property in the “Data” tab first, but can’t update that either. Code sample included below, followed by the logs output. We’re on the free plan, using the React Native SDK, version 1.1.6.  Code snippet used for setting new user property Logs from the attempt to set the user property

Attribution user properties disappear from the user profile

I had users utm_properties as their attribution properties.I have set them up with the latest Browser SDK 2.0After some events these properties disappear from the user properties completely for certain users, I will not find any utm_source, utm_campaign in the list of properties for a specific user, but the user HAD it before.For example, I saw the user came from p-max_… campaign, but now the user is not filtered under this condition and has no utm_campaign. After Payment Integration Succeeded event there is not utm_properties for this user.Where do I have it wrong?

Duplicate events ingested

For the past couple of months, I've noticed duplicate events being ingested, which are visible on my Amplitude dashboard. These duplicates appear about once every several thousand events and have the exact same timestamp down to the millisecond. I don't believe I'm sending duplicates, and even if I were, the timestamps would likely differ.Does anyone have any insights into what might be the issue? I'm still using the https://api.amplitude.com/httpapi endpoint. Is this a known problem with the older endpoint compared to the new HTTP 2 API?

Data is not being collected

We’ve integrated Amplitude on our product. We tested it works well, but since last night (Asia/Seoul 9/19 02:30 AM) no events are displayed on the amplitude dashboard. We’ve checked we are sending event data to the amplitude through developer mode on chrome. Why this is happening?

Amplitude data qps limitation (per second) for streaming web/app event data

Hi!We have been using Amplitude for a while and would like to know if there is any throughput (qps) data limitation per second for streaming data. We know there is data limitation for sending / importing data from 3rd party. Would like to understand if there are any hard limitation of web / app streaming event data per user per second in Amplitude, so that we can better design our usage.  Thanks!
