Hi Yuanyuan, thanks for your swift response.

Would it help your case if it is configured to be dynamic?

I am not entirely sure what you mean here. Based on your response, I checked out page-view-tracking.ts in the Amplitude-TypeScript library. From my testing, it appears that the function I provide to trackOn is evaluated each time I navigate within the browser, meaning it re-evaluates, not just on the initial load.

I tried using trackOn since I could not find any other options. Ideally, I would like tenant to work similarly to amplitude.setUserId(), where userId is set before the session initialises. Do you happen to know of any way to set a user property before Amplitude begins tracking?

Thanks again for your help.

Hi Yuanyuan, we are using Amplitude in a Next.js application, which means Amplitude is initialised only once. Subsequent URL changes will not reinitialise Amplitude, as the view updates without a full page reload. Hope this answers your question.

Hi Yuanyang, thank you for your reply the other day. I have applied the code on our staging environment to first call identify and then amplitude.init. However, the traffic still shows events being sent without a tenant value.

We are using the 'Any Active Event' option provided by Amplitude.

Is there anything I might be missing? During local testing, I also noticed events are sent without a tenant, even when the init call is placed after identify

Here’s my code

useEffect(() => {
  if (!userId) {
    return;
  }

  const identifyEvent = new amplitude.Identify();
  identifyEvent.setOnce('tenant', tenant);
  amplitude.identify(identifyEvent);
  amplitude.init(AMPLITUDE_ID, {
    userId,
  });
}, }userId, tenant]);

And here are the results

The result is similar to what I share with you earlier a week ago

Would you be able to share any additional insights or check with the engineering team? I would greatly appreciate it. Thank you!

Thank you Yuanyuan for your support. Looking forward to your response. For now, have a great weekend!

Hi @Trung Vo !
I haven’t tested it, but I think it could work.
https://github.com/amplitude/Amplitude-TypeScript/blob/main/examples/plugins/page-view-tracking-enrichment/index.ts
By adding a "pageViewTrackingEnrichment" plugin, you could perform an identify only when event.event_type == 'Start session'

Thank you so much for your input @Roque Argañaraz !

@Trung Vo What Roque mentioned would work and I have confirmed it with the engineer . 

Example code: 

// Set tenant user property on session start event
const tenantUserPropertyPlugin = (): EnrichmentPlugin => {
  return {
    execute: async (event: Event) => {
      if (event.event_type === 'session_start')
      //   "user_properties": {
      //   "$setOnce": {
      //     "tenant": "tenant-id"
      //   }
      event.user_properties = {
        ...event.user_properties,
        "$setOnce": {
          "tenant": "tenant-id"
        },
      };
      return event;
    },
  }
}

amplitude.add(tenantUserPropertyPlugin());

amplitude.init('API-KEY', 'USER-ID', {
  logLevel: LogLevel.Debug
});

Thank you, Yuanyuan and Roque, for your input—it looks very promising. I have pushed the changes to our staging environment for testing and will monitor them over the next few days. I will keep you updated on the results.
