API for Biometric Attendance Machines

Introduction

CAMS supports the Web API for the biometric time and attendance machines (Fingerprint, Face Recognition, Card, Palm) and access control machines, which can be integrated with a website or any web application hosted at a domain or public IP. It provides RESTful APIs and Callback APIs for various operations to communicate with the biometric machines back and forth.

We provide two set of APIs

Attendance API: This calls back your URL, whenever a attendance gets registered in the machine.
Management API: This will help for adding, deleting, updating the user in the machine through your software. Also, your sevrer will be notified whenever a new user is added or fingerprint is updated in the machine manually. You can call this API only from a specific server as per the IP configured.

Attendance API: Get Live Attendance Record

An HTTP(port:80) URL should be exposed from your server and submitted with us. We would associate the URL to the machine at CAMS DataServer. Once the URL is associated, whenever the attendance gets registered in the machine, the submitted URL will be called automatically with realtime attendance information. Now user can maintain the records in their database as per your business logic. If you are looking for a non-standard HTTP/HTTPS port while testing your application, then you can use 53124 for a short while
The Attendance URL will be called whenever a new attendance gets registered with the following parameters in POST

stgid->service tag id, means machine id, alpha-numeric data (eg: ST-KY16010101)
userid->alpha-numeric user id
att_time->timestamp of attendance date & time, it will be in epoch format. sample value is 1424051296, it meant "Monday, February 16, 2015 13:48:16"
att_type-> in for check in, and out for check out
auth_token(optional)-> Your alphanumeric string; you would be sharing a 64 digit alphanumeric key which will be sent along with the every call to your URL.

The URL should return "ok" (no json, no double quotes, no xml, just a plain text) in the response, once your server is processed the attendance record. If "ok" is not returned, the URL will be called every time, again and again in every 3 hours with the same attendance records. If the your server is down, the attendance records will try to reach the URL in every 3 hours.

Management API: Add User

RESTful API for adding users in the machine from your web application, will be provided as per the discussion with the customer

Management API: Delete User

RESTful API for deleting users from the machine from your web application, will be provided as per the discussion with the customer

Management API: Notify your server during manual operation in the machine

Your server will be notified for the cases when machine is opearted manually for adding the user or updating the fingerprint/face/card/palm

Biometric Attendance SDK for Connecting to Web Application

Are you looking for fingerprint attendane system SDK?: Before answering, let us understand, what does SDK mean?. SDK means, a development tool or some set of programs that needed to perform a certain operations, and the code of the SDK will be part of the main application once the application is developed with the help of SDK. For CAMS systems, SDK is not required, all the operations are exuected by the CallBack URL and RESTful URLs. So, for integrating the biometric machine with your websites/webapplication or any web based softwares/portals like OpenERP, ERPNext, HRAPP, Zoho, SAP, Tally and etc., what you need is, Just API!. But it can be claimed as online SDK for fingerprint attendance system or biometric attendance system, if you wish.

How does communication between machine and your web application happen?

CAMS Machines are tightly coupled with CAMS DataServer. Attendance information from machine will be updated to your server by passing through cams data server. Adding or removing users in the machine shall be triggered through APIs exposed by the data server and, the data server will communicate with the machine and sends the response back to your server

The punches recorded when the device was online, will be posted to your server by real time.

The punches recorded when the device was offline will be posted to your server one by one while device comes online. The order of the data shall be varying from device to device. So, the business logic should be built assuming the old punch data can come after new punch data

Want to receive data without comming through CAMS Dataserver?

Yes. We provide the windows lite version protocol engine which should be installed at your windows server. Once its installed, You web api endpoints will start getting triggered whenever attendance is registered at the device. The Cost, Actiation cost and Yearly License cost are applied. And the Protocol engine costs 3000 USD

Intranet Communication

If your complete systems are running one intranet or you dont like to expose your devices to the internet or your server is not hosted at the internet server then, You can install our lite version protocol engine at your local server and get it communicated with your web application as per our API specification. Engine should have communicate with the internet at least once in a qurarter. The implementation time is 30 days. Please note that, still API Activation and Yearly License costs are applicable.

Sample Programs

PHP Program to receive the biometric attendance data

Download the sample PHP file from Download Here! to connect with the biometric machine. If you want to test, how to connect the CAMS biometric or fingerprint attendance machine with your website, just place this downloaded file at you server and share us the URL of this file. We would configure the URL and associate to the machine in the CAMS data server.

Now whenever an attendance is registered in the machine, you can see cams-attendance-record.txt gets generated in the same location where you have placed the PHP file, and the same file will be updated with real time attendance data. Now you can update this code to store in your own DB. You need to make sure that your machine is connected to the online. Following is the code snippet for your quick reference

<?php
// PHP program to receive the attendance data from CAMS biometric time and attendance system, and access control system

	$content= 'stgid: ' . $_POST["stgid"] . ",\t";
	$content= $content . 'userid: ' . $_POST['userid'] . ",\t";
	$content= $content . 'att_time: ' . $_POST['att_time'] . ",\t";
	$content= $content . 'att_type: ' . $_POST['att_type'] . "\t";
	$content= $content . 'auth_token: ' . $_POST['auth_token'] . "\n";


	// We capture all the incoming data from CAMS into file: cams-attendance-record.txt.
	// If you need to maintain it in your own database, you need to impletement the same here.

	$file = fopen("cams-attendance-record.txt","a");
	fwrite($file, $content);
	fclose($file);

	header("Content-Type: application/text;charset=utf-8");
	http_response_code(200);
	echo 'ok';

// You can test this url through postman with POST body parameter of above varables or try with curl command as below
// curl -d "att_type=ot-out&stgid=ST-KY1X000325&att_time=1518792241&userid=2536&auth_token=" -X POST http://localhost/cams-attendance.php
// the results will be avilable in http://localhost/cams-attendance-record.txt
