I wrote the below code

    def werobot_view():
        timestamp = request.args.get('timestamp', '')
        nonce = request.args.get('nonce', '')
        signature = request.args.get('signature', '')
        if (not robot.check_signature(timestamp, nonce, signature)):
            return (robot.make_error_page(html.escape(request.url)), 403)
        if (request.method == 'GET'):
            return request.args['echostr']
        message = robot.parse_message(request.data, timestamp=timestamp, nonce=nonce, msg_signature=request.args.get('msg_signature', ''))
        response = make_response(robot.get_encrypted_reply(message))
        response.headers['content_type'] = 'application/xml'
        return response
    return werobot_view

What's a good function header?
