What's in the Brightspace developer platform?

«  Brightspace API Reference   ·  [   home  ·   reference  ·   community   |   search  ·   index   ·  routing table   ·  scopes table   ]   ·  Core concepts  »

Brightspace includes all the APIs and tools that developers use to create valuable, integrated solutions for their customers. If you are new to integrating with D2L’s products, then you can use the documentation on this site to understand the state-of-the-world for extensibility at D2L.

Community Resources. Developers have access to the Developer Community of Practice that houses a set of resources including support forums, a developer blog, code samples, and the available developer support paths.

Known Issues/Fixed Issues List. The known issues and fixed issues lists for the developer platform are available in the Brightspace Community’s Documentation section. For known issues, you can find release specific information within the Cumulative Known Issues List document and for the fixed issues, within the Release Notes document.

All our documentation is open and we are working to provide clear tools and programs. We host all our available open software in our Brightspace repository on GitHub.

Technology features

Web 2.0 integrated and decoupled. We’ve based our architecture upon the practices of Web 2.0 and cloud services that permit richly integrated apps, easy configuration, and operational independence. All access to our system is supported through HTTP and HTTPS calls.

Oauth 2.0. Our support for OAuth2 Authorization Code Grant workflows ensures that we can transparently support all customer authentication scenarios involving your applications. Also, by ensuring that all API routes into an LMS occur within the acting context of a particular user login, service administrators can be confident that activating your application is a safe and constrained step to take.

REST/JSON standards. As a result of using RESTful APIs and JSON data structures, we provide a broad and well-supported technology base for our platform. You will find many off-the-shelf tools you can use to help simplify your work. Additionally, we provide open-source library wrappers for a number of languages with an emphasis on prioritizing the more sophisticated authentication steps of your application’s interaction with an LMS.

Extensibility Areas. Our continually expanding suite of APIs provide access to a variety of technical functionality:



Org and structural

Retrieve and update organizational structure, course lists, user information, and more


View and create content components and resources for a course

Assignments and grades

Facilitate assignment and assessment-related features


Access to ePortfolio Collections, Artifacts, and activities of electronic portfolios

Current release changes

Our Brightspace ILP in continuous delivery provides these new features and changes since the release of June 2024:

Learning Environment. Version 20.24.7 of the Learning Environment includes these changes:

Previous changes. You can find details about previous platform releases on the history topic page.

API deprecation and obsolescence

With this release, the versions of our product component API contracts introduced with the following specific product components become (or remain) deprecated. While you can still call the routes in these contracts on the Learning Suites that have historically supported them, you should plan to migrate to the new API contracts available on your back-end service with due priority.

Obsolete API contracts or services

API deprecation and obsolescence. We are serving notice that as of the Brightspace 20.25.1 release (projected for January 2025), the API contracts introduced with Learning Suites v20.23 will be deprecated and the API contracts introduced with the Learning Suite v20.22 (and earlier) will become obsolete.

End Of Life for Notification Number user notification APIs. We are serving notice that in this July release (20.24.7), we have removed the small collection of actions (and related attributes) for user notification via notification number that are no longer used by clients and no longer have a supporting product feature in the back-end service.

Deprecation of legacy authentication workflow. As of Brightspace 20.23.1 release (January 2023) we have deprecated support for the legacy ID-Key authentication system. We encourage clients using this legacy authentication system to move to using OAuth2 with due priority.

Versions and migration

All API routes to an LMS component are versioned, and include a version negotiation process. This process allows your applications to gracefully adapt to the product components that a customer has active. Additionally, it lets D2L maintain overlapping API versions in a particular product installation, giving your application’s development a way to transition to new features along with your customers, gradually.

The following table shows the association between various product versions and the Brightspace APIs and services they offer. Each table column shows, for a major LMS platform release version:

  • The earliest and latest supported API contract versions provided either by an individual product component along with that product component’s release version (first six rows), or by the overall Learning Suite release version (ext APIs).

    Where a product component introduces a new API contract with a minor platform release version, this additional support gets noted (for example, LE added the 1.67 API contract as of LMS v20.23.1).

  • Marked with an asterisk (‘*’); as of Suite 20.24.1’s release (January 2024), the API contracts introduced with Learning Suite 20.22 have become deprecated. You should plan to move off these routes with all due priority.

  • Marked with a caret (‘^’); as of Suite 20.24.1’s release (January 2024), the API contracts introduced with all versions of the Learning Suite prior to 20.22 have become obsolete: they may or may not still be present on your back-end service, and will not receive any support by D2L. You should move off the routes in these contracts immediately and adopt the versions of these routes in newer, supported contracts.

  • Extensibility APIs tie to the overall Learning Suite release version.

LTI support

Brightspace also implements the LTI standard as an LTI platform, to provide third-parties with a way to, as an LTI tool, integrate their services with Brightspace’s user experience in a standards-based way incorporating robust, service-to-service trust.

Brightspace supports several versions of LTI:

  • Prior to Suite 20.19.9’s release, Brightspace supported LTI 1.0 and LTI 1.1.1.

  • With the release of Suite 20.19.9, Brightspace added support for LTI 1.1.2.

  • With the release of Suite 20.19.10, Brightspace added support for LTI Advantage Complete (LTI 1.3 core, Assignment & Grade Services v2, Deep Linking v2, and Names & Roles Provisioning Service v2).

  • With the release of Suite 20.21.4, Brightspace added support for the LTI Dynamic Registration specification.


We provide support for Brightspace extensibility through a number of support paths, depending upon the nature of your issue or question.
