Microsoft Graph Todo API doesn't return all task lists

Question

The Microsoft Graph API does not appear to return all of my To Do Lists. It seems to return only the first 96 (determined alphabetically) and does not recover anything after that.

There is no nextlink -- even though the nextlink is properly surfaced when I limit $top=5 etc. Setting $top to a huge value does not fix the problem; the only returned data is only the first 96 To Do Lists.

Other users are also observing this behavior: https://learn.microsoft.com/en-us/answers/questions/270572/microsoftgraph-todo-api-only-returns-10-tasks.html

I should also add that the term $search does not appear supported by the API. I cannot even search for one of my To Do Lists that starts with the letter "Z", for example.

Hi @Mo T ,

I am able to replicate the issue. I have more than 100 todo lists but not able to fetch all even after using $top parameter.
Then I tried using this Endpoint https://graph.microsoft.com/v1.0/me/todo/lists/delta and able to fetch all the lists. Using this Endpoint you can enumerate all the todo lists using the nextLink property.

Example reference: refer below screenshot from Graph Explorer. With this Endpoint I am able to fetch all 110 todo lists:

Hope this helps.
