API to download course content

Hello @Alistair.Y.947

Thankyou for reaching out to the Brightspace Community.

To programmatically retrieve ContentObjectId values for a given OrgUnitId, you can use the Brightspace Content API:

GET /d2l/api/le/(version)/{orgUnitId}/content/root/

and

GET /d2l/api/le/(version)/(orgUnitId)/content/modules/(moduleId)/structure/

These endpoints return all content modules, topics, and their ContentObjectIds.

You’ll find these under:

Valence API > Learning Environment (LE) > Content
https://docs.valence.desire2learn.com/reference.html

• Get root-level modules
  GET /d2l/api/le/(version)/{orgUnitId}/content/root/
• Get the structure of a module (children, topics, submodules)
  GET /d2l/api/le/(version)/{orgUnitId}/content/modules/{moduleId}/structure/
• Get topic details (files, links, metadata)
  GET /d2l/api/le/(version)/{orgUnitId}/content/topics/{topicId}

These endpoint returns the entire hierarchical content structure including:

Id → ContentObjectId
Title
Type (Module, Topic, Link, etc.)
Child objects

From this response you can extract Id → ContentObjectId

Alternatively, you mentioned you're already pulling the Content Object Schema Plugin (BDS).
BDS is not a live API — it is an asynchronous data export — but it does provide:

ContentObjectId
OrgUnitId
Title
ContentObjectType
etc.

>How to use BDS:

Call Data Hub API to request the dataset download link
Download the CSV
Filter rows by OrgUnitId

Hope this helps.

Regards,

Ashwin Ravi
