}This endpoint appends a note to a task that already exists in the EMR. To find a task’s
emr_task_id, perform a live fetch with POST /v1/patients/fetch and include: ["tasks"] — each task in the response carries its emr_task_id.Request Parameters
- emr_task_id (string, required): The EMR ID of the task to append the note to. Obtain this from the
tasks[]array returned byPOST /v1/patients/fetchwithinclude: ["tasks"]. - note (string, required): The note body content.
