Deep Linking Return

Where a tool posts the content a teacher selected. You never call this — LTIAAS advertises its URL to the tool inside the deep linking ID Token.

LTIAAS verifies the tool's signed response, then relays the selection to your Service URL as a DEEP_LINKING_RESPONSE service request. The reply is an HTML page that submits itself, so the browser carries the selection to your server.

caution

Only ltiResourceLink content items are accepted. Any other type fails with 400 UNSUPPORTED_CONTENT_ITEM_TYPE.

Path Parameters

contextId string required

The URL-encoded context identifier — the same context value you supplied when starting the launch.
