Contents

The Learning Tools Interoperability® actions let an organization manage the LTI® registrations, deployments, and links available to particular organization units. Callers can use these routes to fetch, register, deploy, update, and remove entries for LTI tools and LTI links. Note that each created LTI link will have a unique D2LID assigned so you can identify a link independently of the org unit with which it’s registered; however, you cannot register a single LTI link with more than one org unit. Registrations and deployments can only be created at the organization. These routes apply to LTI 1.3+ only.

Note

These structures and routes apply only to LTI Advantage (LTI v1.3+). You can also refer to the reference for legacy LTI support (LTI v1.1.x). The LTI API routes are fulfilled by the LE product component and included in the LE API contract version. The ‘lti’ product component listed in version blocks (such as Version.ProductVersions) indicates the level of LTI standard the platform supports, and not the API contract version for these routes.

Tool Registration

LTI.CreateRegistrationData

When a client invokes an action to register or update an already registered LTI tool for an organization, it should provide a structure like this:

{
    "IsEnabled": <boolean>,
    "Name": <string>,
    "Description": null|<string>,
    "Domain": <string>,
    "RedirectUrls": [ <string>, ... ],
    "OpenIDConnectLoginUrl": <string>,
    "KeysetUrl": null|<string>,
    "EnabledExtensions": [ <number:EXTENSION_T>, ... ],
    "SendInstitutionRole": <boolean>,
    "CustomParameters": [ { <composite:LTI.CustomParameters> }, ... ]  // Added with LE API v1.46
}
CustomParameters

With LE API v1.46 and later, you pass any custom parameters as name-value pairs in this required property; if you need no custom parameters for this LTI link, you should provide an empty array. Supported custom parameters will show as Substitution Parameters in Brightspace.

With LE API v1.45 and earlier, you may not provide this property.

LTI.RegistrationData

When a client invokes an action that would retrieve the registration information for an LTI tool, the Learning Service sends back a structure like this:

{
    "ClientId": <GUID>,
    "IsEnabled": <boolean>,
    "Name": <string>,
    "Description": null|<string>,
    "Domain": <string>,
    "RedirectUrls": [ <string>, ... ],
    "OpenIDConnectLoginUrl": <string>,
    "KeysetUrl": <string>,
    "EnabledExtensions": [ <number:EXTENSION_T>, ... ],
    "SendInstitutionRole": <boolean>,
    "BrightspaceAudience": <string>,
    "BrightspaceIssuer": <string>,
    "BrightspaceKeysetURL": <string>,
    "BrightspaceOAuth2AccessTokenURL": <string>,
    "BrightspaceOIDCAuthenticationEndpoint": <string>,
    "CustomParameters": [ { <composite:LTI.CustomParameters> }, ... ]  // Added with LE API v1.46
}
Brightspace* properties

All the Brightspace* properties are Brightspace values that should be shared back to the tool.

Tool Deployment

LTI.CreateDeploymentData

When a client invokes an action to deploy or update an already deployed LTI tool for an organization, it should provide a structure like this:

{
    "ClientId": <GUID>,
    "IsEnabled": <boolean>,
    "Name": <string>,
    "Description": null|<string>,
    "EnabledExtensions": [ <number:EXTENSION_T>, ... ],
    "Anonymous": <boolean>,
    "SendOrgUnitInformation": <boolean>,
    "SendUserFirstName": <boolean>,
    "SendUserMiddleName": <boolean>,
    "SendUserLastName": <boolean>,
    "SendUserEmail": <boolean>,
    "SendD2LUserId": <boolean>,
    "SendD2LUsername": <boolean>,
    "SendD2LOrgDefinedId": <boolean>,
    "SendLinkTitle": <boolean>,
    "SendLinkDescription": <boolean>,
    "PreProvisioning": <boolean>,
    "CustomParameters": [ { <composite:LTI.CustomParameters> }, ... ]  // Added with LE API v1.46
}
PreProvisioning

Security setting to send classlist including users not known to tool.

CustomParameters

With LE API v1.46 and later, you pass any custom parameters as name-value pairs in this required property; if you need no custom parameters for this LTI link, you should provide an empty array. Supported custom parameters will show as Substitution Parameters in Brightspace.

With LE API v1.45 and earlier, you may not provide this property.

LTI.DeploymentData

When a client invokes an action that would retrieve the deployment information for an LTI tool, the Learning Service sends back a structure like this:

{
    "DeploymentId": <GUID>,
    "ClientId": <GUID>,
    "IsEnabled": <boolean>,
    "Name": <string>,
    "Description": null|<string>,
    "EnabledExtensions ": [ <number:EXTENSION_T>, ... ],
    "AvailableExtensions": [ <number:EXTENSION_T>, ... ],
    "Anonymous": <boolean>,
    "SendOrgUnitInformation": <boolean>,
    "SendUserFirstName": <boolean>,
    "SendUserMiddleName": <boolean>,
    "SendUserLastName": <boolean>,
    "SendUserEmail": <boolean>,
    "SendD2LUserId": <boolean>,
    "SendD2LUsername": <boolean>,

    "IsAvailable": <boolean>,
    "CustomParameters": [ { <composite:LTI.CustomParameters> }, ... ]  // Added with LE API v1.46
}
PreProvisioning

Security setting to send classlist including users not known to tool.

AvailableExtensions, EnableExtensions

For an extension to be active it must be in both the AvailableExtensions and EnabledExtensions lists.

Tool Deployment Sharing

LTI.CreateSharingRuleData

When a client invokes an create a sharing rule that will make an LTI Deployment available to an org unit they should send this structure:

{
    "SharingOrgUnitId":  <number:D2LID>,
    "ShareWithOrgUnit": <boolean>,
    "ShareWithDescendants": <boolean>
}
LTI.UpdateSharingRuleData

When a client invokes an update a sharing rule that will make an LTI Deployment available to an org unit they should send this structure:

{
    "ShareWithOrgUnit": <boolean>,
    "ShareWithDescendants": <boolean>
}
LTI.OrgUnitSharingRuleData

When a client invokes an action to retrieve the sharing information for an already registered LTI Deployment they will receive this structure:

{
    "SharingOrgUnitId":  <number:D2LID>,
    "ShareWithOrgUnit": <boolean>,
    "ShareWithDescendants": <boolean>,
    "Inherited": null|<boolean>
}
Inherited

Determines if an org unit has been shared to by having a parent that is shared with all descendants.

Migration

LTI.MigrationData

When a client invokes an action to migrate a 1.1 LTI link to an LTI Advantage link, they should send this structure:

{
    "DeploymentId":  <GUID>,
    "ToolProviderId": <number:D2LID>|null,
}
ToolProviderId

A null ToolProviderId should be used when the LTI link has its own key and secret used for signing during launch. ToolProviderId can also be left null when migrating remote plugins as the tool provider linked to the remote plugin will be used by default.
