[API] Create task with reminder

[API] Create task with reminder

Hi,

I am trying to create a task over the API with a reminer but I can't find the field name to provide to set this reminder and the frequency of the reminder. I tried "Remind At", "Reminder At", "Start Date1" but none of those works. There is no information in the API documentation.
I found a subject about this from 5 years ago, out of date...

This documentation requires an update : there is no information about the fields we can provide and the format of them, I had to try and gess the fields to link a task with a lead ! I had to try and gess how to set the owner of the task and also how to set an email notification !

Thanks for your help.
