I'm trying to make an LTI Tool Provider for embedding content via ContentItemSelection, but I'm having problem with the gradepassback parameters. When a student makes an attempt I expect Blackboard to send me lis_outcome_service_url and lis_result_sourcedid. This doesn't happen for content created via ContentItem messages.
For tool provider creation I use Building Blocks -> LTI ToolProviders -> Register Provider Domain(with url, key, secret)
After TP creation Manage placements -> Create Placements(with launch_url)
To create a content use -> Build Content -> Previously created Placement
