Start timer vía API without end date

Hello,

I’m looking forward to make an API request, POST one, just to start a timmer. I have the ID for worskapce and project ID. Start time will be filled with the date that API request will be done. But I don’t want to set the end date.

I mean, I will start timer via API to begin a task, and when I finish that task, I will run another script or go to website to stop that timer.

Reading Clockify API Documentation , end date it’s mandatory.

Is there any other way to start a timer without ending date?

Thanks in advance.
