The configuration variable actions let an organization read the configuration values that direct the operation of a back-end learning service.

Attributes

CVSCOPE_T

Possible values to describe configuration variable scope (that is, the org units and users affected by the variable’s value) and the way you can edit the variable (formerly known as the “type” of a configuration variable).

Value

Applies to…

System

the instance, including all orgs

Org

the org, and all descendant org units

OrgUnit

an org unit

Role

a role, independent of user enrollment

User

a user independent of enrollment

UserOrgUnit

a user enrolled within an org unit context
CVTYPE_T

Possible values to describe configuration variable value type, and the way you can expect to provide and receive these values through the API.

Listed in the AllowedValues property for a variable
ConfigVariable.Definition

When you make a query about a configuration variable’s definition, the service provides a JSON block like this:

{
    "ConfigId": <string:GUID>,
    "Name": <string>,
    "Scope": <string:CVSCOPE_T>,
    "Description": <string>,
    "DataType": <string:CVTYPE_T>,
    "DefaultValue": <string>,
    "CanEditSystemValue": <boolean>,
    "CanEditOverrideValues": <boolean>,
    "IsSensitiveData": <boolean>,
    "AllowedValues": null|[
        { "Value": <string> },
        { "Value": <string> }, ...
    ]
}
AllowedValues

Null for any configuration variable other than those of type enum. For enum types, this property contains an array of the allowed values the variable can contain.

IsSensitiveData

If true, the value will be obfuscated when stored in the database, and the value will not be directly visible through the learning service’s user interface, or through the Brightspace APIs.

For example, this means that you will not be able to read back password values through the API once they’re set: sensitive data values should come back as empty strings when fetched through the APIs.

CanEditSystemValue and CanEditOverrideValues

Org Admin users will never have CanEditSystemValue, but may have CanEditOverrideValues, depending on the variable in question.

Installation Admin users will always have identical values for these two properties, the value depending on the variable in question.

ConfigVariable.Values

When you make a query about a configuration variable’s current value state, the service provides a JSON block like this:

{
    "ConfigId": <string:GUID>,
    "DefaultValue": <string>,
    "SystemValue": <string>|null,
    "OrgValue": <string>|null,
    "NumOrgUnitValues": <number>,
    "NumRoleValues": <number>
}
DefaultValue

The non-modifiable value for the configuration variable provided when the instance gets created. If no other value gets provided for the configuration variable at another scope, this value gets applied.

SystemValue and OrgValue

The SystemValue is the value for the configuration variable that applies to all orgs residing in that learning service instance. This overrides the DefaultValue, if set.

The OrgValue is the value for the configuration variable that applies to a single org residing in the instance. This overrides the SystemValue, if set.

If either of these properties is null, it’s an indication that the value applied at that level comes from the next level up that has a value. Thus, if SystemValue is null, the value applied will come from the DefaultValue property; if the OrgValue is null, the value applied will come from the SystemValue property (if not null), or the DefaultValue property (if the SystemValue property is null).

Note

Note that “” (the empty string) is a valid value and different from null; if one of these properties has the value “”, then that value gets applied, and not the value assigned to the next level up.

ConfigVariable.ConfigSystemValue

Describes the configuration variable assigned for the system instance.

{
    "SystemValue": <string>|null
}
ConfigVariable.ConfigOrgValue

Describes the configuration variable assigned for an org inside the system instance.

{
    "OrgValue": <string>|null
}
ConfigVariable.OrgUnitValue

Describes the configuration variable value assigned for a particular org unit.

{
    "OrgUnitId": <number:D2LID>,
    "Value": <string>|null
}
ConfigVariable.SpecifiedOrgUnitValue

When you must provide a new value for a configuration value assigned for a particular org unit, you provide a structure like this one:

{
    "OrgUnitValue": <string>|null
}
ConfigVariable.RoleValue

Describes the configuration variable value assigned for a particular role.

{
    "RoleId": <number:D2LID>,
    "Value": <string>|null
}
ConfigVariable.SpecifiedRoleValue

When you must provide a new value for a configuration value assigned for a particular role, you provide a structure like this one:

{
    "RoleValue": <string>|null
}
ConfigVariable.ResolverValue

Describes the strategy the service will use to resolve the value of a configuration variable.

{
   "ouTypeSequence": [ <number:D2LID>, ... ]
}
ouTypeSequence

Array of OrgUnitType identifiers. This array may not contain any duplicates, and may not contain more than five elements.

Actions

Configuration variable API actions belong to three groups:

Definitions

GET /d2l/api/lp/(version)/configVariables/definitions/

Retrieve the definitions for all the configuration variables the user has access to view.

Parameters:
Query Parameters:

  • search (string) – Optional. Case-insensitive search string to match against the full Name of a configuration variable.

  • bookmark (string) – Optional. Bookmark to use for fetching next data set segment.

Status Codes:
API Versions:

  • 1.43+ – Route first appears in LMS v20.23.5.

  • 1.35-1.42 – Deprecated as of LMS v20.24.1.

  • 1.34- – Obsolete as of LMS v20.24.1.

Input. You can use a bookmark query parameter as a paging offset, to indicate that the service should return the segment of results immediately following your bookmark.

You can use a search query parameter to filter the result set to those configuration variables with a Name property that contains your search string.

Return. This action returns a paged result set containing the resulting Definition data blocks for the segment following your bookmark parameter (or the first segment, if the parameter is empty or missing).

Note

This action employs the configuration variable’s ConfigId property enclosed within the Definition block as the paging control value. You can fetch the segment of results following any configuration variable’s entry in the entire data set by passing that variable’s ConfigId as the bookmark value.

Resolver

To resolve the value for an org unit configuration variable, the back-end service uses the first value found in these locations, tested in order:

  1. The current org unit itself.

  2. In order, for each org unit type in the org unit’s ResolverValue.ouTypeSequence property array: walk up the ancestor chain of the current org unit, considering only ancestors that match that type.

  3. The current org.

  4. The system.
