You can delay a request (or if scheduled the start of the schedule) by providing the _delay parameter (or X-Zeplo-Delay header) and a number of seconds to delay by. For example, you may want to send an e-mail 50 minutes after a new user signs up, or delete an accounts data after 30 days.

A _delay=600 would be a delay of 10 minutes.

Delay Until

Alternatively, you can specify _delay_until query parameter (or X-Zeplo-Delay-Until header) to set the unix timestamp of the time to run the request.
