Checkout Event with Multiple Products

Hello, I´m new to Amplitude.Recently I discovered a few errors with the implementation that was done at my company before I started.And I would like some practical examples to show my IT team so we can fix it.One of the errors encontered was Check Out / Cart with Multiple ProductsAs Revenue = Price x QuantityBut what if you have two different priced products.Our implementation was “adding” the prices, adding the quantities and multiplying … but obviously this is wrong.What is the best way to solve this?Precalculate an average price based on quantities??

Device type displaying as "Apple iPhone"

On a User Composition chart I have that composes by Device Type, there is a large segment for the device type “Apple iPhone” – however, there are a bunch of individual models of the iPhone below – iPhone 12 Pro, iPhone X, iPhone 7 Plus, etc...I really want to know the composition of that larger iPhone category. Is this something I have configured incorrectly?

Before/After Pages?

Is it possible to see what page a user came from (even if from an outside source) or what page they went to after a particular event?Thinking beyond the limitations of funnels.What drove a user to this particular page or where did they go after leaving?

Analysis with a dynamic date

Hey,I’m creating a Funnel Analysis to find out user/account count who performed specific events in an order in 7 days from their first date, but I also need to eliminate the users who haven’t had any events after 19 days of their sign up.Is there a way to enter the opposite of this filter? (like after 19 days of first use) Thank you!Gozde

Filtering Out Employees / Job Applicants

Hello, I am looking for a way to filter out specific users in a backwards compatible manner. The scenario is the following: We have some of our employees and job applicants creating some accounts in our production environment and we would like to filter out all of their activity from our various charts and analyses. We have come up with a simple tagging system, i.e. tagging the user as “employee” or “applicant” in a custom user property. However, the user properties are time-based, so any events that have happened before we set the user property are still included in the charts. I am therefore looking for a way to look at specific events while using the CURRENT user properties of the users, as opposed to the user properties the user had at the time the event happened. If this is possible, any insight on how you have approached a similar situation would be greatly appreciated!  Cheers, Julien

Is ATT prompt a must to use amplitude event tracking?

Hi, I would like to know whether we have to use ATT prompt to use amplitude analysis. I have been thinking, as the data that we are collecting in amplitude cannot specify personal identity,It’s possible not to show the ATT prompt.(we don’t have the Attribution tool yet, which I know for sure that we need ATT prompt) I was wondering whether it is possible to just see the user activities without ATT promptif we collect the data that are not connected to user personaly, and that are not connected to attribution data (like SNS channel, etc) by the way, we are getting the info via HTTP API not SDK thanks! with best regards, Flor

How to Create and Save Custom Filters in Event Property

I have an Event called ‘Page View’ with properties such as ‘Page Slug’, ‘Page Route’. Is it possible to save a custom filter on Page Slug?Eg:I would like to create a custom filter WHERE ‘Page Slug’ = {‘apple’, ‘orange’, ‘banana’, ‘mango’, ‘watermelon’}We use this filter in many places, and there are over 50 values in the filter. The alternative is to send it as a property of its own, but we’d ideally like to see it for historical data as well.

No events returned after the first launch

Hi! I’ve encountered strange user behavior, which I suppose might be the problem connected with analytics. We have an event called first_launch that fires off when a user launches the app for the first time. This event should be followed by another event telling that the subscription screen is shown. They go one after another and normally should work even if the user opened and immediately closed the app. However, I see that 2.5% of users only get the event first_launch along with two standard Start Session events before and after it. Strangely, the first Start Session event has a Session ID equal to -1. We couldn’t reproduce that situation, so I thought it would be a good idea to ask Amplitude gurus what it can possibly be. :)I’d appreciate any ideas on that issue. P/S: Also, what may Session ID equal to -1 mean?

[Dashboard REST API] Filtering events by users who performed another event

Hi everyone!I’m trying to replicate a chart query via the Dashboard REST API, though I’m having trouble adding a “who performed” filter to the query.The chart query I’m trying to match is as follows:The part I’m having trouble with is the “and who performed “Signed up >= 1 time any time in each day”. This is a simplified version of where I’ve got to, but looking through the documentation I haven’t seen any way to specify a filter for the event count performed by each specific user on each day.The documentation seems to suggest that any chart produced by the dashboard is possible to query via the API as well, so I assume it’s possible somehow?eventData = { "event_type": "_active", "filters":[ { "subprop_type": "user", "subprop_key": "gp:initial_utm_source", "subprop_op": "is", "subprop_value":["cpc"] },{ "subprop_type": "user", "subprop_key": "???", "subprop_op": "greater or equal", "subprop_value":[1] } ]};const url = `https://ampl

What should be the approach to track push notifications?

Hello! We have a mobile application with push notifications provided by Firebase. I’m trying to find some information about using Amplitude with push notifications.What I’d like to do:Track push sends events via server-side API Track push notification clicks (is it even possible?) Track opens from push notifications (it is implemented yet)I was trying to implement 1st before but I faced a problem that all users become “active” users because of server-side events. So, I saw them in DAU but actually they were offline, I just send an event that the push was sent. My questions:Is it possible to exclude server-side events from counting of the DAU? Is this approach good?Thanks a lot,Stan

How to get separate stats for web and mobile app version names?

We have a mobile app (where Amplitude captures the version number automatically), and a web app (where we call setVersionName explicitly).Now when I try to see how many users are using the latest web version (User Composition by Version), I get mobile app version names mixed in, even after setting Platform to Web.What am I doing wrong?

Creating Custom Event Properties

Hi, I wanted to know if it is possible to create custom event properties on top of already existing event properties? We have created custom events (eg: Event C = Either Event A or Event B) in the past, I was wondering if we could do soemthing similar with event properties (eg: Property C = concatenate Property A, ‘-’, Property B), or is it something that we’ll have to send as a new event property? Thank you.

A bug or I didin't understood the unbounded retention?

Hey community, I might have a silly question but still I couldn’t find an answer myself so here I am.On many retention graphs that I created when I switch to the unbounded retention I see areas where the graph goes up, meaning that the number of people returned on the day n+1 is greater than on the day n, which, if I got the defenition of the unbounded retention right, is impossible.Can you please help me with this puzzle?Thanks!

Is there a way to get user property sums?

We need to sum two user properties. Is there a way to get this? I’m guessing the best way would be to get SQL access, but short of that, is there any other way? We’re not looking for event properties, just user properties.

New vs Returning users' segments.

Hey there,I'm a big fan of Amplitude and I find it really amazing tool. Surprisingly I have an issue with the simplest report (as it supposed to be). I'm talking about Users: New vs Returning report.How can I properly compare the segments of New users vs Returning users?I need to analyze the behavior patterns for new vs returning users I've used tons of variants an no one seems reliable enough. What is the right way to do this?Thanks a lot !

Amplitude IDs confusion

Hey Team,Our app Steppen uses Amplitude for tracking on app use by our users. Steppen is a social fitness app and requires a login process when you download the app.  We are finding that in our "active user count" there are a number (15-20%) of amplitude ID's coming up which are not being attributed to User ID which is what normally happens when a user opens the app and uses it.  Our initial hypothesis was that the user is downloading the app then clicking on it to sign up and then deciding not to sign up. However we are having the same amplitude ID come onto the app on multiple different days and what is recorded is simply that they are only accessing the first sign up page and nothing more. We think it is strange that a user would come onto the app multiple times (one Amplitude ID seems to have come on 9 times) and seems not create an account and use the app.See below a few screen shots of the user flows We are unsure what this user is, is the data not being recorded for this user or

Can we set the options after initiating the SDK?

Hi,We are using JavaScript SDK on our website. We want to enable attribution (utm, referrer etc.). After looking at the documentation, I see the options have to be enabled along with init command. Can we also enable these options after the init separately. We want do this because the SDK is placed on the web source code and we want to enable these options from GTM.

Can't receive click events fired from Google Tag Manager

I set up event and event trigger in GTM and found that AMP can only capture event trigger by page viewThe tags were fired correctly according to the Tag Assistant’s feedback under the debugger mode. But I just can’t see them logged in Amplitude.This is not the first time using this method, it worked well months ago. However, I found this problem yesterday and I just can’t figure out what’s the problem with my setup or if there were updates or bugs from AMP.Can anyone point me in the direction? Thanks!
