Events

We encountered some confusion when using objects and arrays of objects as properties for custom events. We found that these were being stored as the string [object object] when viewed in the properties dashboard.

After consulting with Max AI, the recommended solution is to JSON.stringify() these properties before sending the event.

To improve the developer experience and prevent others from encountering the same issue, could the documentation be updated to clearly outline how object and array property types should be handled, perhaps by explicitly stating the need for stringification or providing this as a recommended practice?

How does posthog categorise an event as active and stale? Like after how many days of inactivity of that event is it categorised as Stale. Also in what field is this stored as stale? Have checked all the event properties but it is seen nowhere. But when the stale event is searched in Activities and then events, we can see stale written there

It's not clear to me why a user's distinct ID should be a uuidv7, over, say, a unique email address. In many apps, users are uniquely identified by their email. While I understand I can attach this as a property, is there really an important distinction between types of distinct identifiers when capturing server-side events?

Is there a way only track part of our users to make the results load faster and maybe even more important decrease the billing costs?

Hi, i need to pick a key value from a property e.g customData that i sent in my custom event. CustomData is an object from which i need to pick some key values that i need to apply filter on. How can i do that? When adding a filter it shows the customEvent in the property dropdown but how do i pick its nested key value?

I need to set up path aliases, so that I can easily filter dashboards or insights by certain pages. Something along like this alias "Dashboard" would map all paths that follow a pattern like "Company/{id}/dashboard".

It's impractical to always write a regex for this and a big barrier for casual users. How can I achieve something like this? Basically, like actions can be defined via the toolbar, it would be great to also identify "pages" like this.

Here is the grammatically corrected version:

I need to call the API of my app when there is a change in a feature flag or when someone enables or disables a feature flag. Is there any event available in PostHog for this?

Is it possible to capture events where user clicking on "Back" or "Forward" in the browser?

I currently do not need to track some of my custom events, but I don't want to remove them from the code. Is there a way to stop tracking them by adding them to the "blacklist" in the Posthog admin so that they don't waste their quota?

Hey! I created a custom event 'copy-response':

posthog.capture('copy-response', {
    message_id: message.id,
    request_type: message.type_question,
});

I have two questions about the type of the properties 'message_id' and 'request_type':

1- If I explicitly specify their types in the code, does PostHog use that instead of its automatic detection? Does it override what PostHog guesses?

2- What happens if the values don't match the types PostHog expects? Does it discard the value, set it to null, or raise an error?

Thanks!

Hi there! Is there a way to find "usages" of an event (e.g. in insights)? Use case e.g.: I want to rename an event for naming consistency and update all insights accordingly. Is there some support for this in PostHog?

Hello everyone, I'm not sure when this little hedgehog appeared in the event properties overview. I understood that all posthog properties with a "$" in front of them have this little hedgehog. However, this is not the case, as "app version", which I am sending as versions along, is an additional property, and it does not have a "$" in front of it.

Hi! If I add tags to my events, can I use them in SQL/ HogQL queries? What would such a query look like? best regards Oskar

How do we add event description? either here or via code? Couldn't find anything related to capturing event in code via posthog.capture in docs nor is the there ability to edit/add description in data management

Hello, Post-hog event capture is not working when i make a build, but when i debug its working as expected. Please give me appropriate solution for this issue I am facing while implementing post-hog service for flutter web app.

Does the activity report happen only in batches? I noticed that after capturing a single event, it is not updated in the activity tab. It is only updated after I send a few (I send pageviews serverside, I have to refresh a couple of times to start seeing the dump of events). I use lambda and await the flushAsync in every capture.

In react I need to put screen name as additional property to default PostHog PageView event. Is it possible or I just need to create own custom event?

Hey,

is it possible to manually send historic pageview events?

Best Philipp

In nextjs app . i set autocapture events but i want capture events only for some pages. is it possible to neglect remaining pages specifically pageview and pageleave event ?

How can i get notifications when a certain event occurs, email, sms or webhook
