Triggers are used to respond to an event. Create triggers to associate Functions with Events. Let's say you want to trigger an email when a bug is created. You can create a send mail function. Next, create a trigger and associate the send mail function with the create a bug event. An email will be sent when a bug is created. Zoho BugTracker supports the following events:

• Run an extension
• Stop and extension
• Install an extension
• Uninstall an extension
• Disable an extension
• Enable an extension
• Update an extension
• Upgrade an extension
• Delete a bug
  
• Create a bug
  
• Add comment to a bug
  
• Update a bug field
