How can I see all events for a particular device ID (not user ID)?

Hello,I would like to see all events happening on my device. I know there’s the option to see events for a particular user ID, but I don’t find how to do it for a device ID.I would like to do that in order to track offline events happening on my iOS mobile app.Thanks!

What event do you use to track funnels for new users? 🤔

New to the community here  👋   and looking forward to hear your thoughts. I’m curious what everyone does to track an activation funnel for new users 🤔 Do you create a funnel chart from Account Creation to the required step (let’s say item purchase) and keep the “completed within” to 90 days (max value I can use)? Or do you divide uniques(purchase) / uniques(account creation) to account for those who converted after more than 90 days? Or do you use another funnel like app open → purchase and have a filter of user performed purchases  = 0 times until the start time of your chart? What if the funnel is different for different cohorts (some users need to take additional steps, let’s say email verification). Do you set custom properties for those users to include them on the relevant funnel analysis? And for non-registered users yet (via device ID), what funnels do you recommend tracking for?

Use eventing to track possible permutations for items in a custom list?

Hello Amplitude Hive Mind,  Wondering if there’s a way (or if it’s even recommended) to use Amplitude eventing to figure out what all the possible permutations in a custom list are? You know this type of list, it’s where you can add/remove headers in a list to create your own custom view (like in excel or any column/row type tool). Basically, we’re trying to figure out how we can understand what the most common custom fields in a list are for all of our users.  Thanks in advance!

How can I track events per subscribed member

We fire an “attendance” event each time a member attends one of our sessions. We’d like to see the number of attendance events divided by the total number of subscribed members over time, so that we have a view of attendance per member. How can we achieve this?I’ve set up a cohort in amplitude that tracks all our subscribed members. I’m not able to figure out how I can use the cohort size in a chart to track the attendances per member, though. Guidance on this would be much appreciated, thanks in advance.

Not receiving any User ID data in User Properties

Hi there,We’re facing an issue where we’re not receiving any [Amplitude] User ID at all under User Properties. Other things, such as Carrier, City, Country, Device family, Device type, DMA, IP address, Language, Library, OS, Platform, Region, Start version and Version are working normally.Our app is built with Flutter and we’ve tested the Flutter plugin and User ID is set correctly. This explains how we set it:abstract class AmplitudeAnalysis { static final _amplitudeAnalysis = Amplitude.getInstance(); static Future<void> init(String apiKey) async => _amplitudeAnalysis.init(apiKey); static Future<void> setUserId(String userId) async => _amplitudeAnalysis.setUserId(userId, startNewSession: true);And this explains where we set it (when the app fetches user profile after user is authenticated)// Set user ID to analitycs unawaited(AppsFlyer.init(profile.uuid)); unawaited(AmplitudeAnalysis.setUserId(profile.uuid));Can someone help us out? For some reason we can’t

Problem with user being identified after opting out for analytics

Hi, I have a question regarding an issue we noticed with user being identified (user personal data, such us email, name, surname and phone number are visible under the userId) after he/she chooses to be opted out for analytics (data collection), as per the GDPR regulation the user has to have a possibility to choose to be opted in or opted out for analytics.Once user registers and chooses to be opted out for analytics, the anonymousId is generated and the user is not identified. If users decides to opt in for analytics, the userId is generated and user is identified (we have visibility on his personal data, such us email, name, surname and phone number...). After some time, if user chooses to be opted out, the user personal data is still visible, I am guessing that is because the amplitudeIds and deviceIds are being merged under one userId. is there a workaround, for the user personal data to be hidden or deleted after the users chooses to be opted out for data collection?

How to display chart in "Bar chart" for each month, not the sum of all months?

Good afternoon, dear Support service!I need to display a chart that should display 2 events A and B for the last 17 months. I would like to display the chart like this https://i.imgur.com/uOXb1ue.png, but when I select "Bar chart", the values are sum up for all 17 months and only 2 bars are displayed (https://i. imgur.com/B5JxTx9.png) and not (17+17=34) as it should be.

How to make a calculation between events and display the result on a "Bar chart" for each month within several months?

Good afternoon, dear Support service!I have a chart that displays 2 events A and B for the last 17 months. I need to do pre-calculations before rendering the chart. It is necessary to subtract event B from event A and display the result on the chart as event A and display event B next to it. We should get something like this https://i.imgur.com/uOXb1ue.png or something close to it. But when I do any calculations through the Formula input, this option for rendering the chart is not available to me. How can I achieve the desired result?

Event Properties not appearing in UI

When sending an event through the Javascript SDK in an application I am using I pass event properties into the sendEvent method. I can see the desired object on the request to Amplitude when it sends the event and the object it attached to the event_properties field on the request payload. However, the event properties are not appearing in the UI and I don’t know why. I saw them for a few events then they stopped all together. I haven’t changed the code regarding sending the event at all so I don’t know what’s happening. Any ideas? Thanks!

Bucketing users by properties for funnel analysis / How do User Filters work

Hi everyone, I’m new here and this might be a well known answer – I tried searching but wasn’t able to find one. My high level goal is to set some user Amplitude properties that I can later on use to bucket users into categories and use that for funnel analysis. The problem is at user signup I don’t have the values for those properties yet (for example the user hasn’t shared their location yet) I wanted to understand first what those two user filtering properties mean: Is the following correct for the following image: Any Events that are performed by any user who at the current time (not the time of the event) their User Property Country = “United States” (i.e. a user who had an empty Country at the time of the event but their current User Property Country = “United States” will be included) Filter applied to event #1  Is the following correct for the following image: Any Events that are performed by any user who at the current time (not the time of the event) their User Property Count

What's the best practice?

Hi, I’m looking for help on setting up a new Amplitude project (through Segment) and I would like to run some of the ideas we have with you. CONTEXTWe have 3 different web projects that are feeding into the same Amplitude project: A) Web app (Single page application). B) Docs pages and our C) Public websiteEvents coming from B and C are sometimes (usually) coming from the anonymous users until they sign up or login and then we identify them.There are many teams involved in the development (especially on the A) and up until now they had a lot of freedom instrumenting their events the way they felt like/needed. That gave us a lot of speed and agility, but it also produced the following problems:3000+ different events 2000+ different properties Sending events with little semantic meaning No descriptions of the events Sending events that should be properties (AB test shown OR DarkMode is on...) Sending 12-15 events just when the app loads (render of the main wrapper, render of the sidebar,

Using an array in one specific event property corresponding to one specific event

Hi Happy to be part of this community. This is my first post here. i am looking to send an event property along with a crash event in below array form. Here I am trying to get the history of incidents x, y, z (from an event property called history) that happened before the actual event crash. Objective is to later classify how many of these x contributed to crash, how many of y contributed to crash etc . Pls note all of x, y, z are not implemented as separate events in amplitude.Sample format:Event name: crashEvent property name: historyEvent property values for history: {x,y,z} in that orderIs above structure ok to move ahead with?If yes, I also want to make a pathfinder or funnel chart or some other chart to understand how many of x usages led to crash and how many of y usages led to crash later. Is there some way in which I can use pathfinder chart and filter out counts by event properties to achieve the same

How to add the calculation of any two events to the ROLLWIN() function?

Hello dear Support service!I have previously submitted a question to the ticket https://community.amplitude.com/building-and-sharing-your-analysis-58/how-can-several-events-with-certain-time-intervals-be-displayed- in-one-chart-1030?postid=3547#post3547 for which you quickly found a solution, for which I am very grateful!Since that ticket is already marked as RESOLVED, I decided to create a new ticket.I need to add another chart where I will use events A and B in it (these can be any events)First I need to do some simple math between events:Event A multiplied by 100 and divided by event B - A*100/B.Next, I need to substitute the result of these calculations in the ROLLWIN() form in order to display the result of the formula on the chart. But I can't do that because the specific syntax of the ROLLWIN() formula doesn't allow me, I can only use:ROLLWIN(UNIQUES, A, 7)ROLLWIN(TOTALS, A, 7)So the question is, how do I substitute the result of my calculations (A*100/B) into the ROLLWIN() form

How can several events with certain time intervals be displayed in one chart?

Good afternoon dear community. I need to create one chart and I have one event which comes from Segment service. I need to display in the chart the sum of incoming events for the previous 30 days. And also for every day during the past 30 days. For example, today is May 11, I need to display the number of events from May 11 to April 11 - this will be the 1st bar in the chart, then I need to display from May 10 to April 10 - this will be the 2nd bar in the chart and so on until the date interval from April 11 to March 11. That is, there will be 30 bars in the chart with intervals in the previous 30 days. The key is that it would not be necessary to manually select date intervals for 30 days, but that they would be set up automatically (the last 30 days were simply taken). I found that under each event you can add a where "Server upload time" condition. That is, there is a way to add 30 identical events and manually add the where "Server upload time" condition to each of them, but the pr

Can Amplitude Rest API query past 365 days?

I’m using the Amplitude REST API and it seems like it only lets us query up to 365 days in the past. However, I would like to give “Lifetime” metrics for my customers and some of them are older than a year.https://developers.amplitude.com/docs/dashboard-rest-api#event-segmentation Is there a way to query longer in the past and if not is that a plan in the dev cycle?
