Change notifications

[Heiinz]

Does this API allow notifications when Todoist items are added, changed or deleted?

There is no such feature, but you can achieve something similar using the GetResourcesAsync method. Here is a simple implementation:

var client = new TodoistClient(Util.GetPassword("todoist.api.key"));

 // Set the initial sync token to "*" to fetch all items in the first request.
var syncToken = "*";

// Perform the initial synchronization to get all items and store the new sync token.
var initialResponse = await client.GetResourcesAsync(syncToken, ResourceType.Items);
syncToken = initialResponse.SyncToken;

while (true)
{
    await Task.Delay(TimeSpan.FromSeconds(10));
    
    // Fetch incremental updates for items using the latest sync token.
    var incrementalResponse = await client.GetResourcesAsync(syncToken, ResourceType.Items);
    
    // Iterate over each updated item received in the incremental response.
    foreach (var item in incrementalResponse.Items)
    {
        Console.WriteLine($"Item {item.Id} was updated");
    }
    
    // Update the sync token for the next iteration to ensure subsequent updates are fetched.
    syncToken = incrementalResponse.SyncToken;
}
