Data Instrumentation

Hi AllI am new to coding API, i am trying to export data from a existing chart, i try to fallow this document to do it, my goal is to export the data for everyday for further analysis.https://developers.amplitude.com/docs/dashboard-rest-api#results-from-an-existing-chartmy question is how do i setup date range parameter in my python code in order to export data from a different date range? thanks in advance,mike--------------------------------------------------------------here is my python code import requestsimport json#import HTTPBasicAuth#pip install pyamplitudeapi_key = "xxxxxxxxxxxxxxxxxxxxxx"secret_key = "xxxxxxxxxxxxxxxxxxxxxxx"response = requests.get('https://amplitude.com/api/3/chart/mk17vo2/query',                         auth=(api_key, secret_key)     )print(response)print(response.json())--------------------------------------------------------------

Subj Can I receive credentials to connect to Amplitude data storage of my project ?

We have both Amplitude and Google Universal Analytics implemented on our mobile app and web. Both of them are implemented via Google Tag Manager using their respective JS SDKs. I understand that both Amplitude and GA are two different tools but here are the numbers for sessions and usersSessionsAmplitude - 49K, Google Analytics - 57KUsersAmplitude - 34.8K, Google Analytics - 39.7KNOTE: Even though the sessions and users are widely different, the number of ecommerce transactions are same on both Amplitude and Google Analytics. 

I would like to either get a list of all active users IDs, event IDs, or session IDs with a time filter of say a few hours, via the API. Is it possible to do so?

Hello. I have a strange situation where event sent from Web SDK does not appear in dashboard. Any other event works, just not this specific one. In the “Govern tab” this event type is set to Active and not Advanced block filters are present.This is how my chrome ampltitude extension looks like, the event is selected. Raw Event JSON{ "device_id": "hB8WMbH8sI3rjPY1ABx5s3", "user_id": "some.user@anymail.com", "timestamp": 1633608691957, "event_id": 2028, "session_id": 1633604498573, "event_type": "Campaign - Investment Selected", "version_name": null, "platform": "Web", "os_name": "Chrome", "os_version": "94", "device_model": "Mac", "language": "en-US", "api_properties": {}, "event_properties": {}, "user_properties": {}, "uuid": "0d41fdf8-7ec6-4f1f-b561-4b0204804cf6", "library": { "name": "amplitude-js", "version": "8.5.0" }, "sequence_number": 2126, "groups": {}, "group_properties": {}, "user_agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko

Until the last time, my team were able to sent sessionId from Segment to amplitude, this is the raw data{ "$insert_id": "f7bfb4e0-0ab9-4860-af4c-6be89409a827", "$insert_key": null, "$schema": 12, "_time": 1631864263470, "adid": null, "amplitude_attribution_ids": [ "2ec0c541748d9d7a0ff71b4e1e25c705" ], "amplitude_event_type": null, "amplitude_id": 299205766988, "app": 330222, "city": null, "client_event_time": "2021-09-17 07:37:43.470000", "client_upload_time": "2021-09-17 07:37:49.919000", "country": null, "data": { }, "device_brand": null, "device_carrier": "From Unity Editor", "device_family": "Predator PH315-52 (Acer)", "device_id": "PRASHANT-DEVICE-ID-TEST-0003", "device_manufacturer": null, "device_model": "Predator PH315-52 (Acer)", "device_type": null, "display_name": "OpenScreen", "dma": null, "event_id": 149928614, "event_properties": { "Spatie\\EventSourcing\\StoredEvents\\ShouldBeStoredmetaData": [ ], "activity_type": "OPEN_SCREEN",

Hi, I am facing an issue where I want to be able to send a button click event instantly, but I have enabled sending batch events for my whole application.I use the JS SDK to initiate like thisamplitudeClient.init('API_KEY', null, { batchEvents: true, ...});With “batchEvents” enabled, events are batched together and uploaded only when the number of unsent events reaches a threshold or after a some seconds have passed since the first unsent event was logged.In my landing page, there is a login button that redirects the user to another domain. I want to track the click event for that button before redirecting, so I log the event and then redirect the user in the callback, like thisamplitudeClient.logEvent('LOGIN_LINK_CLICK', {}, () => { // Redirect the user to the login page})However, since we use “batchEvents”, this event is not sent immediately, so the user has to wait several seconds to be redirected. I want to know if I can send this event immediately, either by disabling

Hi,I only started with Amplitude recently and everything seemed to be going well, however, since Tuesday, I’ve noticed my User Session charts are reporting zero sessions. (It’s Thursday today.)Before you ask, yes, I can be sure that I’ve actually had user sessions since Tuesday. My Amplitude Event Segmentation charts are still reporting events, so there’s a contradiction in the data Amplitude is reporting for Sessions vs Events.Any ideas?

I’m making a utility for others and don’t want to request information, e.g. project name, if I can it via the API. Thanks!

Hi everyone! A bit of context for the question:Newbie question here. We host our platform with an external provider. The access to the events happening there (student registered, canceled, register for a course, etc) are made available to us via Zapier. From there we could use the event and the data to feed other platforms (n8n, local dbs). I wanted to use that trigger to send the same data to amplitude. The thing is, I don’t have access to device_ids from our users (as the data will be ingested using the http api from one of our servers after receiving the data from Zapier). I’m aware that we will lose track of the relation user↔devices but we can live with it.  My doubtWhat would be the best practice with the device_id value?Not sending anything (not sure if that’s possible though) Send a random uuid for every event? Send a random uuid for every user? Any other options I’m not aware of? Same question applies to session_id (I thought about setting a session start that covers 24h) but

Hi,Our business is divided into mobile web and mobile app users. We use the same code base for both web and app users and use JS SDK of Amplitude. We use Adjust as our mobile attribution tool. The problem we face right now is since Amplitude’s JS SDK doesn’t capture IDFA or IDFV or ADID by default whatever the attribution data we get from Adjust is lost. After going through the documentation I understood that we need to send Attribution IDs to Amplitude via HTTP API. Most of our users are guest users.So, the question here is how do we device a solution where we capture attribution information of all the users whether they are signed in or not?One solution I have in my mind is setting the Amplitude User ID to a random UUID (cookie set on the device) which we also store in our Adjust data exports and from our data lake make HTTP calls to Amplitude using user_id as this UUID cookie value and the IDFA or IDFV or ADID information captured by Adjust.  Other suggestion we need is how do we ge

Hello!Using our product, the user always has to create a form and work in this form for the entire user flow. A user can have multiple forms, e.g. projects.I would like to give this form a form_id (3456) and then have defined events, like an excel export within this form. The event has properties like excel_export_price and excel_export_price_automatically_chosen.However, I only care about the last event properties of the excel export of the form of the user. Is there a way I can select the information from the event properties of the last performed event within that form_id?For my analysis, I then want to compare the composition of prices and automatically chosen prices across all my users, on their last excel export.So far, I could only find the historical events in the amplitude help center, this does not really help me, as user can export the Excel as many times as they want to.Also if there is already a way of selecting the last event using Segment.io, this could be interesting to

Hi,I’ve been spending some time in Amplitude’s “Retention Analysis” recently, and we’ve had some great insights! Though am a little confused on the best way to segment users based on events.E.g. Say I have is a music player app (like Spotify), I can create a starting / return event of “Played song”.Then I want to see if users who loaded the “Viewed top 40 hits” are more retained or less than baseline.  I would then go to the “...performed by User” section (on the right) pick users “who performed” “Viewed top 40 hits”, which will create a new segment that I can compare.This makes sense, though I’m confused how the different “any time” dropdowns work e.g.If I pick “during last 30 days” (the default), does that mean in the breakdown, any week AFTER 30 days will only contain users who viewed the top 40 hits in the last 30 days?  This doesn’t seem like a good metric so perhaps using “within” makes more sense - so we can get a better understanding of users in the past and not just users who

We are a young start-up and have never given much thought to what we track in a meaningful way. So when in doubt, we used to track a lot. This helps us now to improve our product step by step. But we are still a long way from turning it into a profitable business. We have already exceeded the event limit a few times and today we received a letter from an Amplitude employee stating that we have been marked on a deletion list. If we don't upgrade, our account could be deleted. I always thought that only the access to the portal is temporarily blocked. Have any of you had this before?Do we really have to fear that our account will be deleted now?We just can't afford to upgrade yet. Best,Christoph

Hello!I am new to Amplitude, and I am attempting to integrate Amplitude with my VR app. At the conclusion of the VR experience, data about the user’s experience is compiled into an event with about 30 or so event properties (each event property is a datapoint generated by the user’s experience).For the date range of my choice, I need to compile and export (as a CSV) all instances of this specific event, along with all event properties, so that I can analyze aggregate results from the VR experience in Excel.How can I accomplish this?

Hi Everyone, I am looking for a way to see a list of User IDs for a specific segment. I’ve been able to find a segment of our users who are super sticky (90% retention on D7) and I’d love to explore the users, understand what they did in their first session etc etc. How do I get the list of users from that segment? 

In our Web App we use Segment’s Page call to track page events.We can select the event in Amplitude but there is no event traffic coming through.These are our Segment settings:and in Amplitude: 

Hi folks,I’m confused wether I should track my usage retention by setting the starting event as “New User” (default) or as “Any Event” (as taught in some Amplitude tutorials).Which one would be more accurate?I’m currently setting as “Any event” => came back and did “Active Event”Thanks

We have a strange thing going on with some of our boolean values. When I look up the event property in Amplitude, it shows values that are uppercase (True/False) as well as other values are lowercase (true/false). We have 3 clients -- iOS, Android, and Web. The iOS one is sending mostly lowercase values, while Android and Web tend to show uppercase values.Event properties have clear cut behavior -- Android/Web is purely uppercase boolean, iOS is purely lowercase. However with User Properties, it seems cross-platform behavior will make some bleed between these rules, although the overarching trend is the same -- Android/Web is upper, iOS is lower.I can’t quite believe this is our doing. Android and Web both use languages that are, by default, lowercase booleans. So there would be no reason for us to change the value sent to Amplitude. Has anyone else ran into this issue? Anything we can do about it?

Hi! I’m new at using amplitude and I’m struggling to understand the relation between stickiness and retention. I have set up a cohort with users that have a strong usage for a specific event (“AddToWishList” event), +5 events during july 2021, and at least one event (“AddToWishList” event) during august 2021. Then I plot a daily retention chart during the period of august 2021 for the same starting event and return event, i.e. “AddToWishList”. Our daily retention is over 40% for the entire period as the figure shows. So far so good. Then I plot the stickiness chart for the same event and time period and cohort. The below chart shows that 18% of users from the segment have emit the event only once and only a few users really “sticked” with the event. Given a +40% of retention for a given cohort, I would have expected a higher stickiness for the same event. This said, I expect users to have used at least 15 days during the same evaluation month. Given the above information, what should b

What values will appear under the Platform user property? It seems like when I use the JS SDK, the Platform will always be Web. 

I want to concatenate two properties with a “/” in the middle. When I try using CONCAT(property-1,property-2), it works fine. However, when I try using CONCAT(property-1,”/”,property-2), it doesn’t work. Could soemone let me know what is the issue here?  Thanks a lot!

Hello, I hope everyone is doing good.We are a Saas, and we connected Adjust to Amplitude to track user behavior depending their sources. The next step for us would be to send these data to Hubspot to update properties of the users in Hubspot with Amplitude data and the Adjust data that have been send to Amplitude. For this we would like to use User ID as matching ID. We have the user ID in Hubspot so that would be easy to match the data from both parts. My question, is, is it possible to send user data to Hubspot for at the end create a workflow in Hubspot to update properties ? Thanks, I hope have been enough clear ! 

Dear community,Our team is relatively new to amplitude, but we already have a large amount of content and are currently brainstorming ideas how best to organise the charts, reports, and teams spaces. Therefore, we are wondering what the best practices are.Looking forward to your ideas! 

I have 1 test project and 1 production.After a proper configuration and tests, we’ve launched analytics in our application, but over some time, some events stopped working at the beginning on test project and a little bit later on production.Limits data is fine. More over most of the events are still coming. Event Limit10M / monthEvents Last Month68Events This Month35Event Usage35 of 10,000,000 (0.000350%) just to make sure that all properties are passing the validation requirements I’ve tried- to remove all properties and send a plain event with no data- to remove insert_id as a unique id per event- change and remove identify propeties the only thing that worked is changing the name of the event. so like before it was `event_name` and after it became `event_name2` and it worked, but I’m still wondering why could it happen so, that only some events are not ingested properly? changing a test project also helped, but I don’t see any difference in configuration of the project
