Missing Web Events due to Ad Blockers and How to Handle It

Hi there Amplitude Community!When using Amplitude Web SDKs, it is possible that some users’ events are not ingested into Amplitude due to ad blockers. Currently, we are not able to estimate the percentage of events that do not get ingested as we do not have the data to support it. While we do not offer official support for circumventing ad-blockers, our Engineering Team has provided a workaround - run a reverse proxy through your own domain. Please note that it is best that this process is done by an Engineer or a Developer as this is a technical workaround.Details on what a proxy service is and how to use it in this setting can be found here:https://www.docs.developers.amplitude.com/analytics/domain-proxy/Hope this helps! ----- please give this post a thumb-up if you find it helpful! This will help us know what content we should publish in the future :) -----Amplitude Team

Can I selectively delete or modify historical data on Amplitude?

Hi Amplitude Community, At the moment, it is not possible to selectively delete or modify historical events. Our current architecture is based on pre-aggregated sets by the hour, day, week and month for users and events. While this allows us to scale well, a limitation is that data is immutableThat being said, we have some options for specific use cases:You can use the Export API to pull all the data from their project, sanitize the data (remove properties), and then perform a Self Backfill and use Batch API to push events into a new Amplitude project. Please note that backfilling data will increase the event volume in your org, which may incur costs. Deleting the old project will not reduce the volume. Do you want just to drop certain data? Amplitude Data's drop filters feature allows you to remove specific event data from your charts at query time. These events are not deleted, and they can be restored to your charts simply by editing or deleting the drop filter. You can read more ab

CSV Export Contains Quotation Marks or Leading Spaces - WHY?

Hi Amplitude Community!We would like to provide context about the quotation marks or leading space in CSV exports. Our engineering team modified exported CSVs to include additional quotation and tab characters in front of all values as a preventative measure for a security risk known with CSV downloads (details here). Attackers can potentially use a formula to inject false data or leak data. And in order to prevent formula triggering cells from running, our engineering team revamped our CSV exports by prefixing quotation and tab characters in front of all values.With that being said, while that security issue remains, we received feedback from customers who said that they were willing to take that risk. Therefore, we implemented a way to export CSVs from Amplitude without any characters in front for those users. If you are willing to take that risk as well, you can enable the feature to remove the spaces in your CSV in your Org Settings section on the Profile page. You can scroll down

Currency Conversion at Amplitude

Hi Amplitude Community, Amplitude currently does not support currency conversion. If you receive revenue in different currencies, then we recommend normalizing to a single currency before you send us revenue data. Amplitude logs the exact revenue value sent to us and treats it as a numerical value (not a currency value). By default, the currency sign we display in the dashboard is the dollar sign, "$".You can change this display under Organizational settings > Projects > Currency Display. Please check this doc for more information: https://help.amplitude.com/hc/en-us/articles/15581410157339. NOTE: Changing the currency display does not modify nor convert the underlying data. ----- please give this post a thumb-up if you find it helpful! This will help us know what content we should publish in the future :) -----Amplitude Team

Instrumenting the Duration Event Property

Media customers that are interested in tracking the amount of time users spend on their products would be interested in instrumenting a property that measures the duration between two events. With this property, users can then measure various items such as Average Property Value, Median Property Value, or use the duration values in complex formulas in our Event Segmentation: Formulas chart.  To track duration, you would need to capture the timestamp of a Start Event and timestamp of an End Event, calculate the difference between the two timestamps, and then pass in the duration as an event property for the End Event. In our demo account this End Event is called Played Song, and here is an example chart: https://analytics.amplitude.com/demo/chart/new/snewb09  As an example for Page View events, let's say you have a Start Event = 'Viewed Home Page' and an End Event = 'Clicked Signup'. When the user fires the 'Viewed Home Page' event, you can create a variable in your code called first_ti

Page title is showing as (none) even though the event is sent

Hello, I’m facing this problem where my Amplitude dashboard still contains empty page titles even though I am seeing the events being sent on the web app. For context, I’m using NextJS. The page title is generated using generateMetadatahttps://nextjs.org/docs/app/api-reference/functions/generate-metadata I am not able to figure out why we are still receiving events with empty page titles. Screenshot of Amplitude Data Table

Track how a user opened the app (via email or push notification)

Hey, we’re developing an invoice approval solution. We sent multiple reminders to users when they have open approvals:A daily email digest that gets send in the morning when you have open approvals A mobile push notificaiton on every new invoice approval request A mobile push notification where you can be @mentioned An email for @mentions etc.We want to learn how users are coming to our app. Are the notifications working? I think for the emails we can use the referrer parameter. But what about push notifications?

Revenue event marked as both Verified and Unverified

I am sending Revenue events from my NodeJS backend using the SDK.As per the documentation, all the revenue events from backend should be marked as Unverified.But some of the events are marked as Verified as well. Some events are also getting duplicated with both Verified and Unverified status. How can I make all of the events to come under one category?

How to use A/B Tests with Amplitude Experiment for Server-Side Email Campaigns and Unauthenticated Users

I need to do an A/B test so that 50% of people receive a certain email and the other 50% receive another email. The email is sent on the server and I am using the experiment flag to decide which email the person should receive. Through email, these people have a link and when they click, they access the same page on my app. On this page there are some events that I want to monitor and compare the email conversion rate. Even though the person is not authenticated, I can know the email because this information exists in the url.In this case, how should I proceed?I have seen that when I fetch the flags providing the user_id it generates the [Experiment] Assignment event but if I don't provide the user_id it doesn't. What is the impact on the experiment of not having this [Experiment] Assignment generated?Do I need to verify the user in order for the experiment to work properly? I'm asking this because we verify the user after they logged in, but at this point the user is not logged in.I'v

How are event properties across different projects counted with regards to the Event Property Limit?

If I have two amplitude projects, with roughly the same schema for events and properties, are event properties with the same in both projects counted toward the limit twice? Currently, my team has two separate amplitude organizations for our test and production environments, and we would like to consolidate them under two separate projects under one organization. However, we are well over half of the total 2000 event property limit so if this would duplicate our event property count it would be a big problem.

Stitching Sessions Across Mobile, Web, and Server-side

Hello everyone,I'm currently trying to figure out how to stitch sessions across sources. Here's the scenario: a user starts a session on our mobile app and is then redirected via an external link to a web flow that also uses our web SDK. I want the web event to be part of the same session that started on the mobile app.Would sending the session ID as a parameter in the redirect link and reusing it to manually set the web session ID accomplish this? Or is there a better way to achieve this? Additionally, some events might be triggered from our backend server using the Amplitude API, which could also set both the user and session IDs.Any suggestions or insights on this would be greatly appreciated!

Multi-tenancy: How to set user properties before tracking events? Alternatives without user property?

Hi everyone, I am working on a multi-tenant application setup where users can access:customer1.example.com for Customer 1's tenant customer2.example.com for Customer 2's tenant And so onIn my code, I have a tenant variable that is sent to Amplitude, as shown below:useEffect(() => { if (!userId || !tenant) { return; } amplitude.init(AMPLITUDE_ID, { userId }); const identifyEvent = new amplitude.Identify(); identifyEvent.setOnce('tenant', tenant); amplitude.identify(identifyEvent);}, [userId, tenant]); I am using @amplitude/analytics-browser version ^2.11.2. This works well for our custom events when triggered (like page load or button clicks) as the tenant property is included.However, we also have Amplitude's autocapture enabled, which captures two initial events on page load that lack the tenant property:[Amplitude] Start Session - missing tenant [Amplitude] Page Viewed - missing tenant Page Load View - includes both tenant and userId See the screenshot for more detailWhen

How to change experiment allocation/ targeting trigger ?

In the current experimentation UI in amplitude. we have the option to target all user or based on user property, but what we need is to target based on specific event.lets imagine that we have a funnel and Viewed landing page (first event in the funnel)  Amplitude normally assign users on variants before or after this event get fired  Clicked on product carousel  this is the event that we want to start assigning when it happen to include only in the experiment users who have done this event and the variants (treatment / control) should get exposed after firing this event.How to work on implementing solution 2. is there is a way from amplitude ui or it should be done using code ? and if with code, how to do it ?
