Use an event property id in place of user_id

Hello, I’m wondering if there’s any way to use a string sent as an event property in place of the user_id for the event. Use-case:  In the product there are events where a user takes action on another users posts e.g. like, comments, etc. In the ‘like sent’ event for example there is an event property called ‘target_user_id’ which has the user_id of the user receiving the like. I’m wondering if there is a way to use this field in a new event so that the result would measure when a user receives a like (instead of gives a like) and could be used in subsequent engagement and retention analysis. Thank you!

How are devices assigned to users?

Our stats show a lot of users with many device IDs. Like 20+. And many Merged IDs.How can I figute out based on what they were merged? It feels unnatural and I want to avoid us having an error in our tracking, missleading the numbers.

Is it possible to group events by properties that are updated after the event?

Hey, In our web app, we trigger a sign-up event the moment a new user signs up. After they sign-up, the user’s properties may get updated as they continue on in our app, for example by filling in their profile information according to what job role they do, which calls a user property update to add these details into amplitude.  I want to create a chart that groups sign-ups by job role (which is only updated after the sign-up event is sent). Is this possible? Our charts can’t seem to do this group by. Everyone’s property is set to (none)—I’m assuming because the property update is only after the event. Any solutions?

User Composition measured by most recent value is wrong

I have a user property called free_trial_group which has 3 possible values (7_days, 30_days and none) and I used it for compositioning: Also I have photos_count user property which I used for segments:  The problem is that values in the resulting pie chart and downloaded users of one of the segments don’t match even though I use most recent value.For exampleI’m downloading those users who have 0 photos_count and are in 7_days free_trial_group:It’s the photos_count column: As you see, almost none of the really has 0 photos_count.Why? Am I doing smth wrong?

What source to use for the new Google Tag Manager Template "Amplitude Analytics Browser SDK"

I send data with GTM and the new Template "Amplitude Analytics Browser SDK", and it works. I see the events as a unknown source.I tried to create it as a source by using the “Google Tag Manager” option but it is stalled at listening for the events coming.I the tried the “Browser SDK” source, but the events send are not automatic detected. I also tried to create a HTTP API source, but with same result.The events i send will not associate them self with the source. How do I ensure that the event form this specific GTM container using the Amplitude Analytics Browser SDK template are recognized as a source, and what source type should I use ? I know i can add a property like “data_source=GTM-W639JT” to all events, but was under the assumption that Sources was to be used for this purpose.

Why are custom events missing standard properties like page_path and page_domain?

My understanding is that if we used the Browser SDK along with the Marketing Analytics SDK, we would get attribution tracking (e.g. UTM params) and the ability to turn on automatic pageview events.However, given discussion in my other question and the benefit of more specific events in amplitude reports, we are implementing custom events for each page view in our site and thus disabling automatic pageview events in the Marketing Analytics SDK.  All good so far.Our custom events are making it through to our development project in Amplitdue but but I’m surprised to see that there are properties missing that I expect to be there like page_path, page_domain which you do get on the automatic generic pageviews if we left that feature on.I then looked at custom events for click tracking we are doing on some buttons and see that they are also missing context of domain and path.No web analytics platform I’m aware of fails to add these properties automatically (which I’d consider essential).

Tracking user scroll

Hi, a team member asked me about tracking scroll events using Amplitude. What is the best practice on capturing events when a user scrolls to a certain part of the page? Let’s say we wanted to have insights into whether users even scroll to the end of a page.Do you think we should do that with Amplitude and what would be the best practice? Thank you Best regards

Java dry run

Hi! I saw that for some SKD is possible to have a dry run. I run my application in different environments and I don’t want to send events to amplitude from all those environments or from a local run or from integrations test.  How can I achieve that in java? Thanks!

Track Landing Pages

Hi all, Newbe here. As far as I understand, Amplitude does not report automatically on web landing pages so trying to find a way to identify them.This is the rationale that makes sense to me:Amplitude init / loads Before sending a page_view event, check if we have previously saved the session ID in browser's local storage. if not, it is a new sessions so we flag the page_view as landing and store session ID from amplitude.getSessionId(); so the next page_view is not identified as such.Does anyone implemented something similar with good results?Thanks in advance.

Missing event tracking my phone

Hi team,Our application Wonder is working on ecommerce payment solution now, we find out some problem with tracking the trigger points in amplitude during working on the funnel of registration process. Based on our operation, the registration process consists of 6 steps, that is start of signup, receiving SMS code of phone, SMS code of email, verification of ID card, selfie verification and finally sign in.In the process of verifying ID card and face, we found out that we failed to track these two events when entering my device id to track in amplitude, which can be shown below. What confuses us is that the event can be recorded in the data tab and also the local log of the flutter frontend, but failed only in tracking my own phone. Secondly, when I tracked my own phone, I found out that my device id changed every time I logged in our application, is there any chance we can fix this id up to the device of the user?Last but not least, there’s a gap between the event volume and the numbe

[HTTP V2 API] Limit auto geo tagging on IP Address to Country (obscure city)

Hi Amplitude community, Currently we are using [HTTP V2 API] to send data to Amplitude, which we automatically get device IP which automatically also translated into Country and City. For user privacy reason, I wonder is it possible to stop IP Geo-tagging at Country level (so we won’t get the City information)? Thanks!

[BUG] Ampli generated code does not compile

Steps to reproduce :A user property named:“Has a GPay something”It will generate:hasAgPaySomething: Boolean? = null,as parameter, but will try to use:*(if (hasAGPaySomething != null)and therefore it doesn’t compile.It can be reproduced using Android and iOS SDKs.Is it the good place to report such issue?

How do you import events from an existing database?

There are different sources from which you can import data. If you have data stored in a warehouse, we have some converters where you can map out the events with actions tracked on your side. For example, if the import is from Google Cloud, you will have guidance from within Amplitude when you start setting up Google Cloud storage import. The steps include:Map certain events to Amplitude fields. Use the converter to guide to make sure that you map out these events to events you have on your side to Amplitude events.Additional ResourcesImport Historical Data into Amplitude Importing and exporting data with Amplitude

How can I import historical Bigquery data into Amplitude?

Looks like this feature is in beta but several folks have been able to figure it out. Would love advice - we’d love to put in historical data so we that we don’t lose any of the information before we connected our codebase to Amplitude. Thanks so much.

Data collection seems to be working fine as usual.So I believe there is some problem with the API.Does anybody have any information regarding this issue?  Thank you

How can we filter based on "If user_property has been X, show all previous events"?

In our specific use case we want to filter our graphs based on a custom user_property called “Department” and “Job title”. We have just used the HTTP V2 API to enrich our user information in Amplitude with that information. However, when we set up the graph it only shows from the date we added the new information. We want to be able to show a graph that displays weekly active users over time for all users who have the property “Department: Accounting”. How can we solve this?

How do you test that Amplitude is set up correctly on our website?

Once you installed Amplitude within your product, the best way to validate if your set up is correct is to send test events to the platform! Data validation is a critical step of ensuring that Amplitude is capturing your expected information.First, you should always create a Test environment for each project in order to test your instrumentation. You can easily do this when you set up your first Project and use the toggle “Use Multiple Environments”. This will allow you to create a multiple environments (including a test one) and link them together across one Tracking Plan. We also recommend using the following tools to help debug and validate your event data:Ingestion Debugger - Allows you to check your requests, events and identify counts, and throttled users or devices User Lookup - You can find yourself and review your event stream. Instrumentation Explorer - This Chrome extension captures each Amplitude event you trigger and display it in the extension popup. Tracking Plan - Valid

Mobile and Web Event Taxonomy

Howdy,I have a question about defines events for web and mobile when the event exists on both platforms.  Background:Out company has a mobile and web app. Most of the features we offer exists on both platforms. Right now, web is almost fully instrumented in Amplitude, but mobile is not. I am in the process of identifying the events for mobile and adding them to Amplitude for instrumentation.  Questions:Instead of creating unique events for mobile, I would like to use the same event (when it exists on all platforms). We’ll easily be able to filter using source or platforms. Is this advised? Or do people generally recommend unique events for mobile and web? If I use the same events, but add the mobile SDKs are a source, the events will show as live regardless of whether they were implemented correctly. Any strategies for debugging live events that you add new sources to?Thanks! I appreciate any feedback people have that have gone through similar event implementations.

Amplitude not logging app version automatically

Amplitude should log app version automatically as given in the react native documentation. It works logs version correctly in one of my apps. However, in the other app I get a blank against version user property and device type. I am using react native sdk to log events. I have enable debugging but couldn’t find anything relevant with it.

Creating custom events based on another event without using the track API

I’m new to amplitude and exploring it in our free trial.In nearly all other analytics products, I’m able to create custom events based on other events without a code change.  For example, based on a generic pageview event that comes in as part of the Amplitude Browser SDK by default. In this case, we’d want to create a custom event called “Homepage view” based on:Event = pageview where path=/This saves us the need to call the track() api on every page since the pageview event is already being captured.  I do not see how to do this and would be shocked if it’s not possible.  Main reason is we are trying to balance cost of implementation on things such as basic pageview events, with friendly definitions that saves everyone in the organization time to specify the where clauses each time they want to create a report of dive into the homepage (or other pages and have to know what filters to apply).Can someone shed light on this?  Is it true that amplitude cannot do this?
