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 generateMetadata https://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.

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.

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!

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 ?

Can you migrate data from Mixpanel to Amplitude?

You can send data from Mixpanel through our backfill process using the Batch API . Some additional instrumentation best practices to remember: Multi-platform products: Different taxonomy = different projects, same taxonomy = same project If different platforms have same taxonomies, then send to the same project (allows for cross-platform analysis) Create test projects: Have a test project for every production project Instrumentation limits: 2000 event types, 2000 event properties, and 1000 user properties Character limits: 1024 for all values, 10,000 for arrays if using append/ prepend operations Data values: ISO-8601 format (YYYY-MM-DD hh:mm:ss) Sensitive data: We recommend NOT sending any PII/ non-compliant with privacy regulation data to Amplitude. Comment here if you hit any roadblocks. The team and your peers are here to help!

Using GTM Template + Autotrack w/ Segment

Hi, we are currently using the Google Tag Manager Template to autotrack page views, form submits, and clicks on our marketing website. We are using Segment in the product once a user signs up to track various product events. We also have Segment on the website, but it’s not integrated with Amplitude there. I’d like to know how we can ensure that Amplitude’s GTM tag uses the Segment anonymousId, so that we can ensure that both Segment + Amplitude utilize the same anonymousId to ensure proper identity resolution once a user logs in or signs up.

Consistent bucketing across unique amplitude experiments

Hi there! We're working on configuring three experiments, one for each platform (web, ios and android) but we want the bucketing to be consistent across all platforms (i.e., a user that sees variant A on web should also see variant A on iOS and Android). If the rollout %, # of variants and variant weight all remain the same, could we apply the same bucketing salt string to all three experiments and expect consistent bucketing for all of our users in these experiments?

I am trying to filter users in a retention chart based on their earnings greater than a certain dollar amount over the past 1.5 years.

Hi, I am trying to filter users in a retention chart based on their earnings greater than a certain dollar amount over the past 1.5 years. However, I can only go till the last 365 days. It says in the Amplitude tutorial that I can filter based on the past 36 months if I used monthly data. I am using monthly chart but I don’t see an option to filter based on months. I tried using cohorts but I still cannot go past 365 days. How can I accomplish this?

Reset Amplitude Session in Backend

Hello! I need to reset the Amplitude session, device ID, and user ID when a user logs out. I'm essentially looking for a way to perform an amplitude.reset() operation on the backend (in Ruby). Is this possible?

I am trying to get the monthly credits earned by our plus customers (Customers who opted for a subscription)

I am trying to get the monthly credits earned by our plus customers (Customers who opted for a subscription). If a customer paid in that month, then his credits should be included and if the customer decided not to pay in that month, credits should not be included. I am not sure how to accomplish this in Amplitude. If I make a condition to check if a customer paid any one of the months, I get the credits of all the months and not the months when he actually paid.

iOS SDK manually changing the experiment variant on the client side

I’m working on an iOS app using the Amplitude SDK, and multiple developers are testing experiments. However, not all testers can access the Amplitude dashboard to change the assigned variants. To facilitate testing without using the dashboard, I’m looking for a way to override or manually set the variant for specific experiments directly on the client side. Does the iOS SDK currently support something like this?

Best chart to use to determine if a feature has activated previously dormant users

Does anyone have advice on how best to see if a new feature has caused previously inactive or low activity users to become more active in your platform? The lifecycle chart doesn’t quite do this as there isn’t a single point in time I’m looking at as someone could perform this event at any given time since release. I’ve only been able to successfully do this by looking at each individual user stream and getting a general sense of their activity but as this feature gains more adoption, I won’t be able to keep up with the scale.

Sending parameters on content vs non content screens

Hi Amplitude team and community, Our team’s React Native-based app serves domestic and international news to users worldwide We're just getting some basic taxonomy and tracking elements organized It's important to us that content screens (a news story, an opinion piece, etc.) send additional parameters and values, like author, publish date, etc. However, we're interested in making sure those content-specific parameters/values (author, publish date, etc.) DO NOT send on non-content pages (like a section front, settings screen or other screen that doesn't have those specifics). Does Amplitude (or do other community members) have any recommendations for or against this practice? And do you recommend any best methods to go about this?

Offline-first mobile app Autocapture feature

Hello, We're developping an offline-first android app and are considering Amplitude for our Analytics. I saw on the community that the SDK will store up to 1000 events when offline, and the recommended way to bypass this limit is to store the event offline ourselves and to send it to the Batch API or the HTTP API when the app is connected to the internet : What about the autocapture feature ? I guess there is no way to use this feature when we store the events offline ourselves and that we can only store the events we create manually ? Or is there a way to disable the 1000 events limit in the configuration of the SDK ?
