Issue in integration of zkt biometric attendance device with HRM

I’m facing issue when integrating zkt biometric device with erpnext. I have integrated my device with zktbio time.net software(avaiable free online) in my pc and my server is running on aws. I have given my api key and api secret key generated from administrator user to local_config.py file. When marking attendance through fingerprint in device im not getting logs of checkin/out of employees in employee checkin document automatically.
