Help to Create Trigger for Ticket Coming in from Gleap.io

I need help with the logic to create a trigger for an autoreply for tickets that are coming from Gleap.io. We have a Gleap-Zendesk integration for feedback/messaging via our mobile app. We also have tickets coming in from our website but those are not part of the Gleap integration. We use 2 support URLs for 2 different groups so need to make sure that the autoreply for our general Support Group does not impact the other group. Is there a way to create a trigger based on a keyword in the body of the ticket?
