Implementing the Command Execution Handler

What are execution handlers?

When a user triggers a command, a deluge function mapped to the command gets executed and renders a response. Upon triggering a command, certain attributes are passed to the deluge code. They are listed below:

Rendering a response:

The return value on executing a command can either be visible to the command executor only or can be posted as a response message to the chat with the help of the deluge task, zoho.cliq.postToChat

Example:

The /traffic command can get the traffic details when mention the from and to locations! Take a look at the sample syntax given below and refer the screenshots to see the command's response.
