Versioning, support, and breaking change policies for Microsoft Graph
This article describes the support and breaking change policies for Microsoft Graph and the versions of the Microsoft Graph API that are currently available.
Support policy and deprecation information
Microsoft Graph follows the Microsoft Lifecycle Policy.
As new versions of the Microsoft Graph REST APIs and Microsoft Graph SDKs are released, earlier versions will be retired. Microsoft declares a version as deprecated at least 24 months in advance of retiring it. Similarly, for individual APIs that are generally available (GA), Microsoft declares an API as deprecated at least 24 months in advance of removing it from the GA version.
When we increment the major version of the API (for example, from v1.0 to v2.0), we are announcing that the current version (in this example, v1.0) is immediately deprecated and we will no longer support it 24 months after the announcement. We might make exceptions to this policy for service security or health reliability issues.
When an API is marked as deprecated, we strongly recommend that you migrate to the latest version as soon as possible. In some cases, we will announce that new applications will have to start using the new APIs a short time after the original APIs are deprecated. In those cases, only active applications that currently use the deprecated APIs can continue to use them.
API contract and non-backward compatible changes
Microsoft Graph has a log of changes across versions. These changes are listed in the Microsoft Graph Changelog. As new functionality and data is added to Microsoft Graph, we will increment the API version number for any non-backward compatible changes to the API.
The following are examples of non-backward compatible changes:
- Changes to the URL or fundamental request/response associated with a resource
- Removal, rename, or change to the type of a declared property
- Removal or rename of APIs or API parameters
- Addition of a required request header
The following are examples of backward compatible changes:
- Addition of properties that are nullable or have a default value
- Addition of a member to an enumeration
- Removal, rename, or change to the type of an open extension
- Removal, rename, or change to the type of an annotation
- Introduction of paging to existing collections
- Changes to error codes
- Changes to the order of properties
- Changes to the length or format of opaque strings, such as resource IDs
Note: Over time, we will update the list of backward compatible changes. If you generate your own client proxies (like WCF clients), our guidance is that your client applications should be prepared to receive properties and derived types not previously defined by the Microsoft Graph API service. Microsoft Graph API follows the guidance described in the Model Versioning section in the Microsoft REST API guidelines.
The following versions of the Microsoft Graph API are currently available.
In general, APIs debut in the beta version and are accessible in the
https://graph.microsoft.com/beta endpoint. For beta API documentation, see Microsoft Graph beta endpoint reference. Expect breaking changes and deprecation of APIs in the beta version from time to time. Do not take a production dependency on beta APIs.
We make no guarantees that a beta feature will be promoted to the current version. When the Microsoft Graph API team believes that a beta feature is ready for general availability, we will add that feature to the latest current version. If the promotion of the feature would result in a breaking change to the current version, the version number will be incremented, with the new version becoming the current version. Our developer community can post feature requests on the Microsoft 365 Developer Platform ideas forum, including requests for new features as well as requests to promote existing beta APIs to the current version.
The current version of Microsoft Graph is v1.0. Exposed under
https://graph.microsoft.com/v1.0, the Microsoft Graph API v1.0 version contains features that are generally available and ready for production use. Browse the documentation for the v1.0 APIs.
An API or feature in Microsoft Graph is labelled as "(preview)" to indicate its behavior is unique in the beta endpoint.
The behavior of most APIs and features in the v1.0 version is in parity with the beta version. "preview" qualifies a minority of APIs and features in one of the following two cases:
- Available in only beta
- Available in beta differently than in v1.0
Like any other API in the beta endpoint, APIs marked in the documentation as "(preview)" may experience breaking changes without notice. Do not access APIs from the beta endpoint in production apps.
As an example, attack simulation training is a feature that has been generally available for administrators in the Microsoft 365 Defender portal. When the REST API for attack simulation training becomes available in Microsoft Graph in only the beta endpoint, the REST API documentation is labelled as "(preview)". The "(preview)" label applies to the REST API and its documentation in Microsoft Graph, even though the service itself is generally available.
Deprecated and unsupported versions
