We added the option to open the */participants API in the participants section of each event. 

Using this API you can call specific parameters and integrate live tracking into your services seamlessly. That way you can identify those participants who have not yet redeemed their tracking keys and send them an email reminder with your mailing solution and provide a convenient race experience.
