Experiment Flag Slack Integration / Webhook

Hey there,Recently we had an incident that was caused by a feature flag being toggled. The incident commander was not aware of the feature flag being toggled to understand what changed in the system. Typically, we push system changes like this to Slack with automations to make it more visible. I noticed there is a Slack integration for some Amplitude features and webhooks for custom monitors, but didn’t see this. What we’re looking for is an integration or webhook that will notify us when a feature flag state is changed. Is there any way to do something like this? Thanks

Question about using Bucketing Slat

I know this is documented quite well here: https://www.docs.developers.amplitude.com/experiment/general/evaluation/implementation/#activationBut this experiment is very important, so I just want to make sure I have this right. We have 3 flags that we want to ensure get to the same users. If we use the same Bucketing Salt for each of the flags, then if we keep the segments and rollout numbers the same, then the same users should receive all 3 flags. Is this correct? Are there any pitfalls that we should be aware of when doing something like this? Thanks in advance.

Can Amplitude do network experimentation?

In my product, users can send each other messages.  If we want to experiment on how messaging works, we can’t run a typical A/B experiment because we need both the sender & recipient to be in the same variant.  One standard way of addressing this is running experiments in different geographic locations, with the assumption that each location has a mostly-closed network.  This hasn’t worked for us, unfortunately, as our separate locations aren’t very similar in the first place so we can’t compare them.  Some companies have the ability to expose experiments based on network clustering.  Is that a feature that Amplitude has?Side note: I have bet on with my engineer that the answer is no. =D  So you won’t disappoint me if that’s the case!The best alternative I can think of is to use BigQuery to manually separate users into clusters, normalize on relevant attributes, try to pair similar clusters to assign to different variants, and upload those assignments as a user property, but I have

New Developer Here With Some UTM Questions

Hello, I am developing amplitude with my ecommerce website smartbettor.ai. I have currently implemented amplitude to track events using the java script sdk. I track payments with stripe and want to track sign ups. After a successful stripe checkout users are redirected to a registration form. The only way to complete sign up is to complete this registration form so I have our ‘sign up’ event being the submission of this form. There are 2 problems with this currently.  Numbers between what stripe says the customer sign ups are and what amplitude is saying are very different. Why would amplitude not be able to track every time this event happens and have significantly less than what stripe says? We want to track utm source. We are starting ad campaigns and want to know what website the user came from. I added these lines which I assumed would track: includeUtm: true, // Track UTM parameters includeReferrer: true, // Track referrer includeGclid: true, // Track Google Click Identifier incl

Any Payload size limit in a variant ?

Questions is:Are there a limit for how large (line, characters, mb) a JSON Payload can be as a part of Feature flag.For a client im implementing Experiment/Feature Flags for IOS and Android. One of the Feature flag planned are to be used as a “All Users 100%” with a payload with info about shops etc. Example of this is an object of all shops, and info for each shop.Intention is to make only one “App Data” feature flag that will grow overtime.For now it’s only 74 lines, and est 1200 characters. But it’s intended to grow over time.

Does anyone have any experience using Amplitude Experiment and Google Tag Manager together?

Does anyone have any experience using Amplitude Experiment and Google Tag Manager together? Our goal is to have Amplitude Experiment set-up like a typical client side tool since it would be difficult to integrate our servers-side code due to some vendor issues. (long-term addressable, but not in the near term) So the basic thought is1> Fire Amplitude Analytics in GTM with the  “Amplitude Analytics Browser SDK” GTM community template. 2> Fire a script tag to initialize the Expierment. <script src=“https://unpkg.com/@amplitude/experiment-js-client@1.9.0/dist/experiment.umd.js”></script> 3> Create a Google Tag Manager Variable which is a custom javascript variable and captures which the experiments and variations the visitor is in. 4> Use those values in the GTM variables to execute or not, the code in our experiments. This is not pretty.  But I haven’t come across much content on Amplitude Experiment, since it is a newer product and not for the lower tier plans. a

Trouble tracking exposure events. Assignment events work, exposure doesn't

Hey guys, can someone give me a hand. I’ve followed pretty much every step in the guides to track exposure, but nothing gets registered on my dashboard. What I’ve done is loading the experiment.start() and then running the line const variant = experiment.variant(‘experiment-one’) [experiment-one is the flag], but it doesn’t work.i tried both the Amplitude and Segment integration, but no luck. This is one way I tried (with Segment → )export async function loadScript() { const promise = new Promise((resolve, reject) => { const script = document.createElement("script"); script.type = "text/javascript"; // script.async = true; // script.defer = true; script.text = ` !function(){var analytics=window.analytics=window.analytics||[];if(!analytics.initialize)if(analytics.invoked)window.console&&console.error&&console.error("Segment snippet included twice.");else{analytics.invoked=!0;analytics.methods=["trackSubmit","trackClick","trackLink","trackForm","page

What is the true conversion(Event level conversion) from "Select Song or Video" to "Play Song or Video", when the Song or Video is selected from "Main Landing Screen". Compare this conversion number by different "Sources" , in the same chart.

Hi, I feel my answer is a little close https://app.amplitude.com/analytics/demo/chart/hjqmr0zx, Is this correct, if not I need little assistance.

Separate Amplitude Experiment deployment or not for SSR server?

BackgroundThe examples in the server side rendering guide for Amplitude Experiment have…a “server” deployment key for initialising the node SDK used to fetch initial variants, see https://www.docs.developers.amplitude.com/experiment/guides/server-side-rendering/#initialize-the-server-sdka “client” deployment key for initialising the javascript SDK ExperimentClient with those initial variants, also used on the server. See first “if” branch here https://www.docs.developers.amplitude.com/experiment/guides/server-side-rendering/#initialize-the-client-sdk-on-render. The “client” deployment key matches that used to initialise the ExperimentClient in the browser in the second “if” branch.However, the Amplitude Experiment Node SSR Demo app here https://github.com/amplitude/experiment-node-server/tree/main/packages/ssr-demo uses an identical “client” deployment key for all three.

Missing User ID in Start Session - GTM

Hi everyone, for my project I use GTM template “Amplitude Analytics Browser SDK” to initialise the Amplitude but I set userId and identify user in the project itself(by calling the newly created amplitude object), because GTM doesn’t have access to the information needed. Also I set timer with 30 retries in case that object is not initialised yet.Now what happens is that for majority of users but not all(around 70%) I can’t see information from identify, as well as User ID, in the user properties of Start Session event . However in the future events of same session the information I send with identify method is present but User ID is still missing. This causes the table in User Look-Up to show Amplitude ID instead of user Id for these events(but if you open the page of the user, he has correct Id). This is applicable only for the 70% of users I mentioned at the beginning, the rest are receiving identify data and userId in Start Session, so further events have userId set.Does anyone kno

How do I correlate time in platform to retention?

We’re working on a tool that is a platform for investigations in a virtual machine. We have a thesis that more time spent in the machine itself is going to be indicative of happy customers, as we meet a broader range of their investigative tasks in platform. I want to test this by seeing if time in platform is predictive of retention. I can measure time in platform on average, but I can’t figure out how to link it back to retention.I’m also open to criticism of the idea in general.

Amplitude Integration via Kotlin Multiplatform (cross-platform)

Hey folks, we are currently on the way towards migration from GA towards Amplitude. We have one iOS and one Android App, and we want to take this opportunity to integrate Amplitude via Kotlin Multiplatform Mobile (KMM).Goal: One business logic for the whole analytics integration in order to reduce the overhead of maintaining it on 2 platform and - most important - consistency among the platforms.Here is a video from GDG in Melbourne last week, talking about that in a more general way:  Does someone here in the community maby has experiences with such an integration? If yes, I would be very happy to get some insights about it. How did go, pitfalls, would you do it again, etc :)Thanks a lot!Best, Manuel
