There are several types of Triggers that can start a workflow. Some can be accessed only when on the Relay Assistant channel (like button taps), others are available at any time (like speaking a phrase by holding down the channel button or a scheduled time).


button This is a tap of the button when a user is on the assistant channel. Can be single tap or double tap.
phrase This is a spoken phrase trigger. It can include one or more words that are spoken into the assistant.
http This is a remote trigger that can be invoked with a http POST.
schedule This is a scheduled trigger based on a date/time. It can also be recurring on a set interval.
on_call_request This is a workflow that starts when you place a call from a Relay endpoint.
on_incoming_call This is a workflow that starts when you receive a call to a Relay endpoint.
