Data Instrumentation

We are using Adjust as attribution tool and forward the data to Amplitude. With iOS14 an the SKAd Network we see aggregated data in Adjust for our paid networks but this data is not forwarded to Amplitude. My understanding is that Amplitude needs the IDFA or IDVF to match the attribution data with actual users, otherwise the data will be dropped. So currently the aggregated data from paid networks on iOS14 is completely missing in Amplitude. In the documentation on this topic (https://help.amplitude.com/hc/en-us/articles/360047228311-FAQ-Apple-s-iOS-14-IDFA-Changes#does-amplitude-require-idfa-on-attribution-events) I stumbled over this sentence: “We are working with attribution vendors to see whether there is any aggregated data that our customers can send to Amplitude.” Any news on that…? 

Hi, I try to filter out my internal users with the domain, with a condition like “domain is not claap”.When I do a segment “domain is claap”, the segment is correctly filtered to list all my claap internal users.However, when I do the segment “domain is not claap”, some of the suers with a claap domain (not all of them) are not correctly filtered out. Note that I also tried all variants “does not contain”, and so on…This pb also appears when I filter on the email directly.I tried to investigate on the root cause (either our instrumentation or the way Amplitude works), but I can’t understand why the filter works to include but not to exclude. For instance the screenshot below illustrates this with a specific user. I would expect segment 2 to return 559 users and not 560 (ie all users). Am I missing something? Thanks for your help!

We're developing Kids games, therefore we're using Amplitude in COPPA mode however in COPPA mode Amplitude does not allow to collect IDFV besides IDFA, city, IP address and location tracking.  However since IDFV is a publisher level ID, Apple does not not restrict the collection IDFV which helps us to identify same users among our games. Is there any chance that Amplitude collects IDFV in COPPA mode ? Or any workarounds ?

I’ve setup a cohort on uninstalls as we have quite a few users that reinstall our app (so the query is based on uninstall events being > install events, to correctly capture uninstalls). I’d like to see this over a longer term time horizon than 30 days, or alternatively if possible, add the cohort to an event segmentation so i can run it that way. Is this at all possible?

Hello there,I have my product (a device) data stored in Microsoft Azure Data Explorer. The important events that happened in the device are captured and stored in json format in a table with time-stamp and device-identifier.How to import this data to Amplitude for analytics? Is there some form of connector for Microsoft Azure Data Explorer?I have seen the Batch API. Is it the only way to import in my case? What tool do you suggest here , a python script or NodeJS Amplitude SDK to write script to download data from our database and use Batch API to import in Amplitude ?   

See the latest Starter plan updates hereStarter plans have access to query up to 1 year of data (could be last 365 days or between n date - n+1year date with only 365 days at max) Plus plans have access to query up to 2 years of data (could be last 24 months or between n month - n+24month) Scholarship/Growth/Enterprise have access to query unlimited years of data  How long does Amplitude retain (and make accessible)our user/event data? 

Is there a way to update the session ID by the user?I set the email as the user id after the user login, but before that i hace in the user id a numeric one, so to keep tracking the same user in the session i want to update the user id in the session. (The email address is not changeable so is unique forever), in another topic is there any way to track the download electron app? and track the same user in the app downloaded by passing session or something like this? 

Can we get hourly report for the active user? On Which bases you can identify new user ? How many users uninstall the application ?

I want to know how may users uninstall the application.

Hello everyone,My team is using Amplitude on our react-native projects (@amplitude/react-native@2.3.3). We’re also using UXCAM to track user’s interactions with our apps. What we would like to do is to link both Amplitude and UXCAM, and we came across this article (https://help.uxcam.com/hc/en-us/articles/360050569672-Amplitude). Quite easy to understand but we have an issue with the last part (Log Amplitude metadata with UXCam). It says we need to get the Amplitude session ID to give it to UXCAM so it can link Amplitude events with UXCAM sessions. But we can’t seem to find this session ID anywhere. Nor can we find the “getSessionID” method. Do we need to install another library or will it be added in the future ?Thanks for you Help ! Camille

If I am adding a condition in cohort definition “The Users who ...had been ‘active’ during last 30 days”, does it mean the user had logged at least one event every day in the past 30 days?  Or does it mean the user had logged at least one event in the past 30 days?

Hi,Is there a way to export the full list of events and their properties?I can export events, but can not find how to export properties.Bill

As currently I can show only todays events performed by user. I can not able to see previous events perform by user.

Hi everyone!I am trying to get list of events with event properties for a user. I see that events are shown in Events Stream on UI, however User Activity API returns OK response, but empty list of events.I send cURL like this based on API documentation:curl -u API_Key:Secret_Key 'https://amplitude.com/api/2/useractivity?user={AmplitudeID}'Please advise what is wrong. Maybe it is a bug? Thanks!

can we get all the array element which are set against any particular key while setting values. or any way to delete any element in array.

Hi! I’m new to the platform and I was wondering whether I could create a cohort based on a particular conversion rate.An example would be if I wanted to study the behaviors (and events, etc) of those with a conversion rate (eg. Purchase) above a particular % or on a top percentile.Maybe I am looking at this the wrong way and there is a tool to do this already baked in :)Thanks!

We have a property that was previously being misreported by one of the clients. We plan to switch to a new property that reports this correctly.Is there a way to view all the charts that make use of an existing property (so we could switch them to use the new property)?

I am using NodeJS SDK to insert events and event_properties using HTTP API v2, and user_properites using identifyMy sample code block looks as belowimport { Identify } from '@amplitude/identify'import * as Amplitude from '@amplitude/node'const client = Amplitude.init(amplitude_api);const identify = new Identify();const payload ={event_type: eventType,device_id: row.deviceid,user_id: row.userid,event_properties: row,event_date: moment(row.timestamp).format('YYYY-MM-DD'),timestamp: new Date(row.timestamp),update_timestamp:new Date().toISOString(),context: {ip: row.ipaddress},// "user_properties": {// user_id: row.userid,// device_id: row.deviceid,// partner_id: row.partnerid,// slotid: row.slotid// },}identify.set('user_id', row.userid).set('device_id',row.deviceid)const userProperties = {'partner_id':row.partner_id as string,'osname':row.osname,'devicetype': row.devicetype}identify.append('partner_id',row.partner_id as string) const identifyEvent = identify.identifyUser('user_id','devic

Hi there, This might seem really picky, but… We’ve got a large number of dashboards / charts that were affected by a recent change a few weeks ago to the series color picker. On this link: https://amplitude.com/blog/amplitude-dashboards-charts, the series color picker at the bottom has 15 separate colors… but a recent change that I couldn’t find in any changelog, seems to have completely changed which colors are applied to which series. The color picker now only contains 12 colors:  While ultimately, that’s fine - these colors are still great, the fundamental problem we’ve run into is that we’ve lost the ability to have colors that also indicate their meaning. Previously, for instance, we had a chart that contained something along the lines of GOOD, WARNING, ERROR, which we were able to indicate using green/yellow/red, but with the recent changes, it’s hard to get the colors to look like they’re indicating the same things.  The purplish red that’s highlighted in the second image is… fi

I'm trying to work out the best way to set up information, so that we're able to utilise the data as we hope in Amplitude. We would like to store the following info:- If a user is pregnant, when they are due (So that we can see how many users are due in a specific period, and extract this for comms)- If a user has multiple children, the birthdates of those children (So that we can see how many users have children under 2, over 2, etc.)What would be the best way to store these, so we could utilise Amplitude to show those charts?

Hi! I’m trying to work out whether it’s possible to group several values within a user property into buckets, but haven’t found a way to do it yet.Specifically, I have a user property with users’ age with values indicating individual ages, and I would like to group them in custom buckets “i.e. 20 to 30 years old”.Can this be done with Amplitude? 

Hi folk  ,Recently, I notice that for any reasons for some of my graphs, data aren’t loaded for the last 7 days tab.I can’t explain why and I would like to know if you have any clue about debugging such situation.What I did:- Check if data for related event was correctly send to amplitude (via network tab in the browser web console)- Since everything look okay I played with other tab (different durations) and everything look okay as well.- Check if it’s a pricing issue since I’m running into the free version at the moment, but again here, didn’t see any mention about that kind of limitation. So here I’m stuck, not able to see my last 7 days data which is super annoying regarde our growth strategy who need to be tested every weeks. Does anyone have a clue ?Thanks in advance for your time & help.Kev

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??

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?

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?
