Public developer preview app manifest

For information on how to enable developer preview, see public developer preview for Microsoft Teams.

Note

If you aren't using developer preview features, including running Teams personal tabs and message extensions in Outlook and Microsoft 365 app, use the app manifest (previously called Teams app manifest) for generally available (GA) features instead.

App manifest describes how the app integrates into the Microsoft Teams platform. Your app manifest must conform to the schema hosted at https://developer.microsoft.com/json-schemas/teams/vDevPreview/MicrosoftTeams.schema.json.

}

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 this manifest is using.

version

Required – String

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

If the app requested permissions change, users are prompted to upgrade and re-consent 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 prerelease and metadata version string extensions aren't supported.

id

Required – Microsoft app ID

The unique Microsoft-generated identifier for this app. The format of the ID is GUID. If you've registered a bot through Microsoft Bot Framework, or your tab's web app already signs in with Microsoft, then you might already have an ID and must enter it here. Otherwise, you must generate a new ID at the Microsoft Application Registration Portal (My Applications), enter it here, and then reuse it when you add a bot.

developer

Required – Object

Specifies information about the developer and their business. For Teams Store apps, the value must match the values that you provide in the Partner Center app submission form.

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 app-specific page on your website.
privacyUrl String 2048 characters ✔️ The https:// URL to the app's privacy policy.
termsOfUseUrl String 2048 characters ✔️ The https:// URL to the app's terms of use.
mpnId String 10 characters The Microsoft Cloud Partner Program (CCP) ID (formerly known as Microsoft Partner Network (MPN) ID) that identifies the partner organization creating the app. Optional
contactInfo Object App developer's contact information.

developer.contactInfo

Optional – Object

Your contact information that is used by customers to contact you through Teams chat or email. Customers may need extra information when evaluating your app or if they have any queries about your app when it doesn't work. Customers can contact you using Teams chat, so request your IT admins to enable external communications in your organization. For more information, see developer provided app and contact information.

Note

You must provide only one contact email address.

We recommend triaging your customer queries in a timely manner and route those internally within your organization, say to other functions to get the answers. It helps improve app adoption, builds developer trust, and increase revenue if you monetize the app.

Name Type Maximum size Required Description
defaultsupport Object ✔️ The default contact information for your app.
defaultsupport.userEmailsForChatSupport Array 10 ✔️ Email address to receive customer queries using Teams chat. While the app manifest allows up to 10 email addresses, Teams uses only the first email address to let IT admins communicate with you. The object is an array with all elements of the type string. The maximum length of email is 80 characters.
defaultsupport.emailsForEmailSupport Array 1 ✔️ Contact email for customer inquiry (Minimum: 1; maximum: 1). The object is an array with all elements of the type string. The maximum length of email is 80 characters.

localizationInfo

Optional – Object

Allows the specification of a default language, and pointers to additional language files. See localization.

Name Type Maximum size Required Description
defaultLanguageTag String ✔️ The language tag for the strings in this app manifest file. For example, en
defaultLanguageFile String 2048 characters A relative file path to the .json file that contains the strings. If unspecified, strings are taken directly from the app manifest file. A default language file is required for agents that support multiple languages.

localizationInfo.additionalLanguages

An array of objects with the following properties to specify additional language translations.

Name Type Maximum size Required Description
languageTag String ✔️ The language tag of the strings in the provided file. For example, es
file String 2048 characters ✔️ A relative file path to the .json file that contains the translated strings.

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.

Name Type Maximum size Required Description
short String 30 characters ✔️ The short display name for the app.
full String 100 characters ✔️ The full name of the app. It's used if the full app name exceeds 30 characters.
abbreviated String 15 characters Abbreviated name for the app; used as the display name on the app bar on the left hand side of the UI. If not specified, short name is used on the app bar.

description

Required – Object

Describes your app to users. For apps submitted to AppSource, these values must match the information in your AppSource entry.

Ensure that your description accurately describes your experience and provides information to help 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 must not be repeated within the long description and must not include any other app name.
