App manifest

Article
12/11/2024

The app manifest (previously called Teams app manifest) describes how your app integrates into the Microsoft Teams product. Your app manifest must conform to the schema hosted at https://developer.microsoft.com/json-schemas/teams/v1.19/MicrosoftTeams.schema.json. Previous versions 1.0, 1.1,...,1.17, and the current version is 1.19 are each supported (using "v1.x" in the URL). Version 1.18 is not available. For more information on the changes made in each version, see app manifest change log and for previous versions, see app manifest versions.

The following table lists TeamsJS version and app manifest versions as per different app scenarios:

App type	TeamsJS version	App manifest version	Next steps
Teams apps extended across Outlook and Microsoft 365	TeamsJS v.2.19.0 or later	v.1.13 or later	Extend a Teams app to run across Microsoft 365 or Create a new Microsoft 365 app
Existing Teams-only apps	Update to TeamsJS v.2.19.0 when possible (v.1.12 is still supported*)	1.12	Understand TeamsJS backwards compatibility and Update to TeamsJS v.2.0
New Teams-only apps	TeamsJS v.2.19.0 or later	1.12	Create a new Teams app using Teams Toolkit

*Use the latest TeamsJS (v.2.19.0 or later) whenever possible, to take advantage of the latest improvements and new feature support including Teams-only apps. TeamsJS v.1.12 continues to be supported, however, no new features or improvements are added. The 1.12 and 1.13 schemas are otherwise the same. For more information, see TeamsJS library.

Note

If your Teams app is using the app manifest version 1.13 or later, ensure that your app meets the criteria to extend your app to run across Microsoft 365 or Outlook.

The following is the sample app manifest schema:

}

The schema defines the following properties:

$schema

Optional, but recommended – String

The https:// URL referencing the JSON Schema for the app manifest.

manifestVersion

Required – String

The version of the app manifest schema that this manifest is using. Use 1.13 to enable Teams app support in Outlook and Microsoft 365 app; use 1.12 (or earlier) for Teams-only apps.

version

Required – String

The version of a specific app. When you update something in your app manifest, the version must be incremented too. This way, when the new app manifest is installed, it overwrites the existing one and the user receives the new functionality. When this app was submitted to the Microsoft Teams Store, the new app manifest must be resubmitted and revalidated. The app users receive the new updated app manifest automatically within few hours after the app manifest is approved.

If the app requests for permissions change, the users are prompted to upgrade and reconsent to the app.

This version string must follow the semver standard (MAJOR.MINOR.PATCH).

Note

If your app includes an Office Add-in, each segment of the version string is limited to a maximum of five digits. The semver standard's pre-release and metadata version string extensions aren't supported.

ID

Required – Microsoft app ID

The ID is a unique Microsoft-generated identifier for the app. The format of the ID is GUID. You have an ID if your bot is registered through the Microsoft Bot Framework. You have an ID if your tab's web app already signs in with Microsoft. You must enter the ID here. Otherwise, you must generate a new ID at the Microsoft Application Registration Portal. Use the same ID if you add a bot.

The ID stored in Teams admin center is the External App ID and it's visible as ExternalID on the traces.

Note

If you are submitting an update to your existing app in AppSource, the ID in your app manifest must not be modified.

developer

Required – Object

Specifies information about your company. For apps submitted to the Teams Store, these values must match the information in your Teams Store listing. For more information, see the Teams Store publishing guidelines. Developer name helps improve your app discoverability in the Teams Store.

Name	Type	Maximum size	Required	Description
`name`	String	32 characters	✔️	The display name for the developer.
`websiteUrl`	String	2048 characters	✔️	The https:// URL to the developer's website. This link must take users to your company or product-specific landing page.
`privacyUrl`	String	2048 characters	✔️	The https:// URL to the developer's privacy policy.
`termsOfUseUrl`	String	2048 characters	✔️	The https:// URL to the developer's terms of use.
`mpnId`	String	10 characters		Optional The Microsoft Cloud Partner Program ID (formerly known as Microsoft Partner Network (MPN) ID) that identifies the partner organization building the app.

name

Required – Object

The name of your app experience, displayed to users in the Teams experience. For apps submitted to AppSource, these values must match the information in your AppSource entry. The values of short and full must be different. App name helps improve your app discoverability in the Teams Store.

Name	Type	Maximum size	Required	Description
`short`	String	30 characters	✔️	The short display name for the app. Use `short` property where the space is limited, such as the app header.
`full`	String	100 characters	✔️	The full name of the app, used if the full app name exceeds 30 characters. Use `full` property where there's more space, such as the app catalog or the app details page.

Note

In the app manifest v1.17 or later the full property is required and for app manifest v1.16 or earlier it isn't required.
The short property is used across all UI surfaces.

description

Required – Object

Describes your app to users. For apps submitted to AppSource, these values must match the information in your AppSource entry. App description helps improve your app discoverability in the Teams Store.

Ensure that your description describes your experience and helps potential customers understand what your experience does. You must note in the full description, if an external account is required for use. The values of short and full must be different. Your short description can't be repeated within the long description and must not include any other app name.

Changing these permissions during app update, causes your users to repeat the consent process after they run the updated app. For more information, see Updating your app.

validDomains

Optional (except Required where noted) – Array of strings

A list of valid domains for websites the app expects to load within the Teams client. Domain listings can include wildcards, for example, *.example.com. The valid domain matches exactly one segment of the domain; if you need to match a.b.example.com then use *.*.example.com. If your tab configuration or content UI navigates to any other domain other than tab configuration, that domain must be specified here.

Do not include the domains of identity providers you want to support in your app. For example, to authenticate using a Google ID, it's required to redirect to accounts.google.com, however, you must not include accounts.google.com in validDomains[].

Teams apps that require their own SharePoint URLs to function well, includes "{teamsitedomain}" in their valid domain list.

Important

Don't add domains that are outside your control, either directly or through wildcards (). For example,.yoursite.com is valid, but *.onmicrosoft.com isn't valid as it isn't under your control.

When using wildcards, the following rules apply:

If a subdomain segment includes a wildcard, it must be the only character in the segment.
Any segment preceding a wildcard segment must also be a wildcard segment.

For example, *.*.domain.com is valid, but foo.*.myteam.domain.com is not valid.

The dummy URL string value mustn't contain domains or URLs that aren't in your control, either directly or through wildcards. For example, `yourapp.onmicrosoft.com` is valid, but `.onmicrosoft.com` isn't valid. The top-level domains are prohibited, for example, `.com`, `*.org`.

Create an app manifest file

If your app doesn't have an app manifest file, you need to create it.

To create an app manifest file:

Use the sample app manifest schema to create a .json file.
Save it in the root of your project folder as manifest.json.

Here's an example of the app manifest schema for a tab app with SSO enabled:

Note

The app manifest example content shown here is only for a tab app. It uses example values for subdomain URI. For more information, see sample app manifest schema.
