A transaction ID (TID) is a unique identifier assigned to each request in a distributed system to track and monitor the request. It can be generated algorithmically to ensure uniqueness across the system and must be generated by an API gateway if not already present. While the TID can take different formats as long as it remains unique for a specified time, common examples include a random string of characters or numbers concatenated with relevant context about the request.
