Code App in Teams Tab not receiving query parameters from Teams deep link (Activity Notification)

Posted on by Sushant Salunkhe

Hi all,

I'm working on a Power Apps Code App embedded in a Microsoft Teams tab, and I’m trying to pass parameters from a Power Automate flow using Microsoft Graph sendActivityNotification.

✅ Scenario

•Teams custom tab app hosting a Power Apps code app

•Sending notification using Power Automate → HTTP → Graph API

•Using topic.webUrl to open the app via Teams deep link

✅ What I’m trying to achieve

Pass a parameter (e.g. record ID or navigation key) from the notification so that when the user clicks it:

•Teams opens the tab

•Power Apps code app receives the parameter

•App navigates to the correct screen/item

✅ What I implemented

Deep link used inside topic.webUrl:

https://teams.microsoft.com/l/entity/<APP_ID>/<PAGE_ID>?tenantId=<TENANT_ID>&context=%7B%22subEntityId%22%3A%22linereports%22%7D

Inside the Power Apps code app:

import { getContext } from "@microsoft/power-apps/app";

const ctx = await getContext();

console.log(ctx.app.queryParams);

❌ Issue

ctx.app.queryParams only contains:

{

"hidenavbar": "true",

"tenantId": "..."

}

👉 Custom parameter (linereports) is not available

✅ Additional attempts

•Tried using TeamsJS:

import { app } from "@microsoft/teams-js";

await app.initialize(); // fails with timeout

Error:

SDK initialization timed out (Ocdi)

✅ Questions

1.Is it possible to access subEntityId (or subPageId) inside a Power Apps code app?

2.Is there a supported way to pass parameters from Teams deep link into a Power Apps code app?

3.Do we need to configure the Teams tab content URL placeholders (e.g. {page.subPageId}) for this to work?

4.Is TeamsJS unsupported inside Power Apps code apps because of the nested iframe?

✅ Expected outcome

Ideally I want:

ctx.app.queryParams.itemId === "linereports"

✅ Any guidance appreciated!

If anyone has implemented this with:

•Power Apps Code Apps

•Teams tab deep linking

•Activity feed notifications

Hi @Sushant Salunkhe,

Found the root cause. In Teams JS SDK v2, the subEntityId from a deep link context is stored in page.subPageId, not in query parameters. The Power Apps Code Apps getContext() exposes queryParams but not the full Teams page context object, which is why your custom parameter doesn't appear.

To answer your specific questions:

1. subEntityId is not directly accessible via ctx.app.queryParams in Code Apps. It's in the Teams JS SDK context at page.subPageId, which getContext() doesn't currently expose in the queryParams map.

2. The supported workaround for passing parameters from a Teams deep link into a Code App: embed your parameter in the webUrl as an actual query

parameter rather than in the context JSON. Change your deep link to:

https://teams.microsoft.com/l/entity/APP_ID/PAGE_ID?tenantId=TENANT_ID&webUrl=https://your-tab-url?itemId=linereports

Then in your Code App read it via ctx.app.queryParams.itemId. Parameters in the webUrl are passed through to the app as queryParams.

3. Yes, configure the Teams tab content URL placeholder {page.subPageId} in your manifest if you go the subEntityId route, but since Code Apps use Power Apps hosting not a custom URL, you can't inject placeholders there directly. The webUrl query parameter approach is more practical.

4. TeamsJS SDK initialization timing out in Code Apps is a confirmed known issue. Code Apps run in an iframe within the Power Apps player which is already in a Teams iframe double-nested iframes break TeamsJS SDK initialization. Don't use TeamsJS directly in Code Apps.

@Sushant Salunkhe

For passing parameters into a Power Apps Code App inside a Teams tab, the most reliable approach is to embed the parameter directly in the webUrl as a query string rather than relying on subEntityId/context. For example:

https://teams.microsoft.com/l/entity/APP_ID/PAGE_ID?tenantId=TENANT_ID&webUrl=https://your-tab-url?itemId=linereports

You can then read it via ctx.app.queryParams.itemId in the Code App. Also worth noting: TeamsJS SDK initialization will time out inside Code Apps because the app runs in a double-nested iframe (Code App inside the Power Apps player inside Teams), so it's best avoided for this scenario.
