Todoist is deprecating links to tasks at the end of 2025 where the link is to the original numeric task ID format. This is the ID that make.com returns when making calls to Todoist, e.g. creating a task. Todoist is now using the alphanumeric v2_ID in its links, possibly in other calls. The v2_ID can be retrieved by an extra call from make.com passing the ID to return the task details including the v2_ID, but it would be better to skip this step and have the v2_ID fully supported in return parameters and calls that required an ID.
