Changes the fields you send; the rest stay as they are, and the window is checked whole, as when it was made. To switch between once and weekly, send start and end in the new form too (and days for weekly). active: false pauses it: it keeps its settings and does nothing. active: true resumes it.

It needs a role that can mute and pause monitors (Owner, Admin and Manager have it by default).

Need an API key? See Getting an API key.
