Rollbar needs to be installed like any other dependency that you intend to use by including it in your deployment package ( Instructions here)

This basically amounts to running

pip install rollbar

Sending a test message to Rollbar

Add the following to import and initialize Rollbar:

import rollbar
rollbar.init( '{{ server_access_token }}', environment='production')

Use the decorator rollbar.lambda_function which will ensure that any errors/messages will be transmitted to Rollbar before your function returns:

def lambda_handler(event, context):
    rollbar.report_message('Hello from Lambda', 'info')
    return 'Hello Lambda'
