409 Client Error on event update PUT

requests.exceptions.HTTPError: 409 Client Error: Conflict for url: https://amplitude.com/api/2/taxonomy/event/XXXXXI’m getting the above error when attempting to update an event via the Taxonomy API. The event updates perfectly on our Alpha build, but fails in production (making it difficult to troubleshoot).The event in question appears to have an “Unexpected” tag in prod, so that might be a factor. I can’t find any documentation about a 409 error.Is anyone able to assist?

Limit of 30 items in a group by or Breakdown table?

Amplitude seems to be showing an incomplete data set on several of my charts. I discovered this seems to be because the Breakdown table below the chart was set to only show the top 12 items (the chart uses a group by expression). I attempted to select all items but it maxed out at “Breakdown showing top 30” (when there are actually 35 items). The UI doesn’t allow me to select or show the other 5.  Is this some kind of Amplitude limitation? I can’t find it documented anywhere. The docs say group by’s are limited to 100 for performance reasons: https://help.amplitude.com/hc/en-us/articles/360031259831But 30 is nowhere near 100. Maybe there’s a bug? Thanks for any help.

Exploiting event properties when the event contains several properties to be reported (Core Web Vitals)

 I’m trying to build a Chart to see the values for CLS, FCP, FID, TTFP and LCP. The events contain all those values within it (as event properties). My goal is to generate a graph with 5 lines, one for each “value”. I wasn’t able to achieve that so far. Do I have to send each value in a separate event to be able to exploit those data like that? That would rather be inefficient. I hope I’m missing something. I’m on the free plan.

Missing events on user look-up

Sometimes, a user is missing information about them such as their device type, device OS, and none of their events are showing up on the user look-up page. We believe this user is using a desktop browser.Could it be that they have a Chrome extension that’s blocking our ability to track them? Or maybe even a VPN?

[Dashboard API] Segmentation for users, who performed another event

Hi, everyone. I didn’t find the answer either in docs or community.The desired result is:How to create the request?My event data is:const eventData = { "event_type": "_all"};What segment definition should be?I’ve found some information about segments here. So, my definition looks like this:const s = [{ group_type: "User", prop: "gp:state", prop_type: "user", op: "is", type: "property", values: ["verified"]},{ op: ">=", type: "event", event_type: "landing.test", filters: [], value: 1, time_type: ???, time_value: ???}, { op: ">=", type: "event", event_type: "test.open_app", filters: [], value: 1, time_type: 'forEachInterval', time_value: 30}]I’m not sure about this construction.What are all the available values for “time_type”?Why I should specify 30 for the “forEachInterval”?Can someone tell me more about “group_type”, ‘prop_type’, ‘type’, ‘event_type’? This parameters are not specified in docs.Thanks for any help!

"New User" - Unique vs Total

Hi! I have a small question - may be it very simple, but i don't find any answers.I am trying to create a simple graph - the number of users who have installed the app.I am using the “New User” metric for this - “A new user is a user who has logged an event for the first time”.When i use “Uniques(New User)” I receive correct results, but if I use “Totals(New Users)” - the final value is increased by ~ 9 times (167->1494) in the same period.According to the documentation, the "new user" event should be registered 1 time and it seems to me that the Total and Uniq in this case should not differ?I plan to use these metrics for further calculations and I need to understand the logic - please help)

Impact of multiple property values on 'where' and 'group by'

Suppose the event stream for a single user is:Monday: ImpressionEvent #1 topic=(none) Tuesday: ImpressionEvent #2 topic=dogs Wednesday: ImpressionEvent #3 topic=catsIf I group-by ‘topic’ for the last 7 days, which value is used for the grouping? What about filter?What I’m seeing is that the earliest value of `topic` is used in the group-by → but that has the consequence that some users with topic=(none) in the segmentation chart, actually have topic=cats when you inspect the user profile page.Is this the expected behavior of am I doing this wrong?

Something wrong with my retention

I have 2 problems with retention graphicsN-day retention shows me on N-day it’s 50% or bigger retention, BUT on 0 day there were 90 users in cohort and on N-day returned only 2 of them. How is it possible 2 of 90 - 50%? Then I decided to check unbounded retention and it’s defenetly broken. If I’m not wronged, unbounded retention can not show us 10% on day 4 and 50% on day 5Is it something wrong with our events? But we send them and it works.How can I fix it?

How do dynamic cohorts work in historical graphs?

Hello,  I’ve created a dynamic cohort of users (“active users”) who performed a set of tracking events “set A” in the last 7 days. When I create a new chart to see “active users” who performed a different set of tracking events “set B” over the last 60 days, how does the dynamic cohort behave?Does the dynamic cohort retroactively adjust to determine the set of users 60 days ago that performed the initial “set A” 60 days ago? ...or does the dynamic cohort define the set of “active users” as of today, and just look at that set list of users 60 days ago? Example:Create dynamic cohort is users who performed tracking event A in last 7 days. As of today, I see 3 users with IDs: 345, 346, 347 I create a chart for tracking event B over the last 60-days I apply a filter on users of the dynamic cohort Will the chart only show me those 3 users? Let’s say users 345, 346, 347 only signed up two weeks ago. If I look at the chart, will I see 0 users of dynamic cohort with event b usage 60-days ago or

Question about User Properties

Dear Amplitude support team,I want to know the same custom user attribute of the same user (the user attribute in the red box in the figure below), if there are changes due to different user behaviors, can these changes be saved at the same time. That is, whether a user property can have multiple different values, similar to DEVICE_ID?Looking forward to your reply.Thank you.kind regards,YuNing Yan

Issue with Time Spent per User analysis

Hi all,I am having an issue during the last two weeks where I experienced that my Time Spent per User and User Sessions went down to zero while the DAU is still showing the users on the platform. Looking at the Session duration configuration I found that no limit (minutes) was set and no related to any starting/ending event.Does anybody know whether it might be related or a hint on what could be going on?Thank you in advance. EDIT: Doing a deeper research, I’ve found that the SessionID is -1 since that. Looks like the session ID is not being set by Amplitude, or does it related to the segment integration?

Using and manipulating date time user properties

Hi,We’ve added a Starting date user property and it has been populated with ISO 8601 values as following: YYYY-MM-DDTHHss”z”It would seem that the values can be queried in events charts with YYYY-MM-DD manually entered values to create segments as detailed in the article belowWhen using a user composition chart then it’s a little more challenging and I’d like to know if it could be possible to trunc the date time and only retain either YYYY-MM-DD or even YYYY only.The other solution we’re considering is to create separate user properties or changing its format to integer with YYYYMMDDAny other recommendation?Thanks!

[Dashboard REST API] How to select 'exact order' option on Funnel analysis?

Hi, I am trying to use Funnel Analysis(https://amplitude.com/api/2/funnels) on Dashboard REST API. According to the API document, it seems that I can set the ‘mode’ parameter where I could select either ‘ordered’ or ‘unordered,’ which seem equivalent to the options ‘this order’ and ‘any order.’ However, I could not find how to choose the ‘exact order’ option on API. Is there any way to implement ‘exact order’ via dashboard rest API?

Fraction of users that perform an event each day of the week

What’s best practice for finding the fraction of users (who perform event A) that perform an event A (at least) once every day of the week?I have tried a solution ​​​​​​to use a Segmentation chart with two segments:Users who performed event A >= 7 times any time in each week Users who performed event A >= 1 time any time in each weekOn the left hand side I chose Any Active Event,using this formula: %: UNIQUES(A1)/UNIQUES(A2),with frequency weekly.My understanding is that this will give me the fraction of event a users that performed event A >= 7 times of the users who have performed event A >= 1 time. However, the “in each” option will include user who performed event A at least X times during each chart interval, which does not met my intended wish to guarantee that each user in segment 1 have performed event A at least once each day, for example a user would also be included if they performed the event 5 times on Monday and 2 times on Saturday...In short, is there a way i

How to set a single funnel with API and Front-end events

Hi guys !I have a question about a funnel I want to analyze with Amplitude, for the “API product” I manage :Some users log in our dashboard (dashboard.company.com) to retrieve their API Key Then they read API Documentation Then navigate through statistics pages (...) When they are done with the dashboard and understood how everything works, they will login and mainly use the whole product through the API. Meaning : They don’t need to come back to the front-end dashboard to use core features. They may come back if they want to check statistics.We would like to use Amplitude to analyze this complete funnel by tracking front-end events (example : API Key Generated) and events generated on our API directly : (example : Webhook subscribed)Is there a way to do this properly with Amplitude ? We only integrated front-end tracking so far.Thanks !
