Triggers, Events, and Functions

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 task is created. You can create a send mail function. Next, create a trigger and associate the send mail function with the create a task event. An email will be sent when a task is created. Zoho Projects supports the following events:

• Run an extension

• Install an extension
• Uninstall an extension
• Disable an extension
• Enable an extension
• Update an extension
• Upgrade an extension
• Delete a task
• Create a task
• Add comment to a task
• Update a task field
