I just realized that when I was looking at the docs yesterday I thought I was checking the reviews section but I was actually on the assignments one, which is why the parameters I was trying out didn’t seem to be working.
With immediately_available_for_lessons and immediately_available_for_review I should be able to get the lessons and reviews currently available, I’m assuming.
There is only one assignment per subject. It is what contains your personal data for the subject. As such it is neither a lesson or a review, but you can tell from the started_at date if or when when the lesson was done
It is possible to export this information from Item Inspector to csv format. You may use a spreadsheet or process the csv file at your convenience. I am not sure if you want to go that route but this is an available option.
In Item Inspector this is named Lesson Date.
In Item Inspector this is called Total Answers Correct.
Lessons available are the Items in the Initiate SRS stage in Item Inspector.
Reviews available are the Items in with a Review Date.
If you export this information you are ready to go.
Item Inspector is a script I wrote. You define which items you are interested in with filters and you define which information you want in the export file. Then you click a button and it does the export. But if you are almost done there may be no point to it.
Edit, the export is to a csv file. You will have to process that to get it to the web book automatically.
