        return { 'textual content': response }
    else:
        return {
            'statusCode': 405,
            'physique': json.dumps("Methodology Not Allowed. This perform have to be known as from Google Chat.")
        }

When Google Chat sends a request, the lambda_handler perform calls the handle_post perform.

3. Let’s change the handle_post perform with the next code:

def handle_post(information):
    if information['type'] == 'MESSAGE':
        user_message = information['message']['text']  
        space_name = information['space']['name']
        return f"Whats up! You stated: {user_message}nThe house title is: {space_name}"

4. Save your file, then run the next command in your terminal to deploy your new code:

The deployment ought to take a couple of minute. When it’s full, you may go to Google Chat and check your new enterprise logic. The next screenshot exhibits an instance chat.
