Geofencing is a location-based technology that defines virtual boundaries around real-world geographical areas. These boundaries, known as geofences, can be customized to specific shapes, such as circles, polygons, or isochrones. The system triggers pre-defined actions or notifications when a person or device enters or exits these defined geofences.
Geofencing technology relies on the Global Positioning System (GPS) or other location-based services to continuously track the real-time location of devices, such as smartphones or GPS-enabled assets. When a device’s location matches the defined geofence parameters, the system detects this containment and initiates the corresponding actions.
Utilizing Geofencing to Automate Dispatching for Field Technicians
Proximity-Based Dispatching: Geofencing allows field service businesses to automate dispatching by assigning tasks to technicians based on their real-time proximity to job sites. When a service request is received, the system automatically identifies the nearest available technician within the geofenced area and dispatches them to the job location.
Efficient Resource Allocation: By utilizing geofencing, dispatchers can optimize resource allocation and ensure the efficient utilization of field technicians. Tasks can be intelligently distributed among technicians based on their locations, minimizing travel time and maximizing productivity.
Real-Time Updates and Notifications: Geofencing enables real-time communication with field technicians. Dispatchers can send updates, instructions, or new assignments directly to technicians’ devices when they enter specific geofenced zones, ensuring they stay informed and responsive.
Benefits of Incorporating Geofencing into the Dispatching Process
- Enhanced Dispatching Accuracy: Geofencing technology ensures accurate dispatching decisions by considering real-time location data. This precision eliminates the risk of assigning tasks to technicians who are far away from the job site, reducing delays and customer wait times.
- Improved Response Times: Automated dispatching through geofencing results in quicker response times to service requests. Technicians are dispatched promptly to nearby locations, enabling them to reach customers faster and provide timely assistance.
- Increased Customer Satisfaction: Businesses can deliver exceptional customer experiences with geofencing-enabled dispatching. Faster response times, reduced wait times, and timely services lead to higher customer satisfaction and loyalty.
- Optimal Resource Utilization: Geofencing helps optimize resource utilization and reduces operational costs. By minimizing travel distances and time, businesses can lower fuel expenses and increase the number of tasks completed per day.

'Authorization': `Bearer ${API_KEY}`,
};
// Make the API call to delete the geofence by ID
const response = await axios.delete(apiEndpoint, { headers });
// Handle the API response
if (response.data.status === 'Ok') {
console.log('Geofence deleted successfully.');
} else {
console.log('Error deleting geofence:', response.data.status);
}
} catch (error) {
console.error('An error occurred:', error.message);
}
}
// Function to delete a batch of geofences by IDs
async function deleteBatchGeofencesByIds(geofenceIds) {
try {
// Prepare the API endpoint with the API key
const apiEndpoint = `${API_BASE_URL}/batch?key=${API_KEY}`;
// Set the API key as an Authorization header
const headers = {
'Authorization': `Bearer ${API_KEY}`,
'Content-Type': 'application/json',
};
// Make the API call to delete the batch of geofences
const response = await axios.delete(apiEndpoint, { headers, data: { ids: geofenceIds } });
// Handle the API response
if (response.data.status === 'Ok') {
console.log('Batch of geofences deleted successfully.');
} else {
console.log('Error deleting batch of geofences:', response.data.status);
}
} catch (error) {
console.error('An error occurred:', error.message);
}
}
// Call the function to delete a single geofence by ID
// Replace 'GEOFENCE_ID' with the actual ID of the geofence you want to delete
deleteGeofenceById('GEOFENCE_ID');
// Call the function to delete a batch of geofences by IDs
// Replace the array elements with the actual IDs of the geofences you want to delete
deleteBatchGeofencesByIds(['GEOFENCE_ID_1', 'GEOFENCE_ID_2']);
Ensure that you replace `’YOUR_API_KEY’` with your actual NextBillion.ai Geofencing API key, `’GEOFENCE_ID’` with the actual ID of the single geofence you want to delete, and `’GEOFENCE_ID_1’`, `’GEOFENCE_ID_2’`, etc., with the actual IDs of the geofences you want to delete in the batch request.
The functions `deleteGeofenceById` and `deleteBatchGeofencesByIds` send DELETE requests to the API to delete a single geofence and a batch of geofences, respectively.
Get a List of Geofences
To get the list of geofences in a field service management application using NextBillion.ai’s Geofence API in Node.js, you can use the following code. This code uses Axios library to make an HTTP GET request to the API:
const axios = require('axios');
// Replace 'YOUR_API_KEY' with your actual NextBillion.ai Geofencing API key

// NextBillion.ai Geofencing API base URL
const API_BASE_URL = 'https://api.nextbillion.io/geofence/list';
// Function to get the list of geofences with pagination and tag filtering
async function getGeofenceList(tags = '', pageNumber = 1, pageSize = 1) {
try {
// Prepare the API endpoint with the API key and optional parameters
const apiEndpoint = `${API_BASE_URL}?key=${API_KEY}&tags=${tags}&pn=${pageNumber}&ps=${pageSize}`;
// Make the API call to get the list of geofences
const response = await axios.get(apiEndpoint);
// Handle the API response
if (response.data.status === 'Ok') {
const geofences = response.data.data.list;
const pagination = response.data.data.page;
console.log('Total number of geofences:', pagination.total);
console.log('Current page number:', pagination.page);
console.log('Maximum items per page:', pagination.size);
console.log('Has more pages:', pagination.hasmore);
if (geofences.length === 0) {
console.log('No geofences found.');
} else {
console.log('List of geofences:');
geofences.forEach((geofence) => {
console.log('Geofence ID:', geofence.id);
console.log('Geofence Name:', geofence.name);
// Add more information you want to display for each geofence
console.log('--------------------------------');
});
}
} else {
console.log('Error getting geofence list:', response.data.status);
}
} catch (error) {
console.error('An error occurred:', error.message);
}
}
// Call the function to get the list of geofences
// Replace 'TAGS' with the comma-separated list of tags to filter geofences by tags
// Replace 'PAGE_NUMBER' and 'PAGE_SIZE' with the desired pagination parameters
getGeofenceList('TAGS', PAGE_NUMBER, PAGE_SIZE);
Ensure you replace ‘YOUR_API_KEY’ with your actual NextBillion.ai Geofencing API key, ‘TAGS’ with the comma-separated list of tags you want to use for filtering geofences (or leave it empty for no filtering), and ‘PAGE_NUMBER’ and ‘PAGE_SIZE’ with the desired pagination parameters.
The function `getGeofenceList` sends a GET request to the API to retrieve the list of geofences with optional tag filtering and pagination. The response will contain information about the geofences that match the provided tags and pagination settings.
Automating Dispatch
To automate dispatch using NextBillion.ai’s Geofence API in Node.js, you can create a script that fetches the list of geofences and then checks if a specific location falls within any of the geofences. ​​Let’s assume that when a point is found within a geofence, we want to automatically dispatch a field technician to that location.
Below is an example code to achieve this:
const axios = require('axios');
// Replace 'YOUR_API_KEY' with your actual NextBillion.ai Geofence API key
const API_KEY = 'YOUR_API_KEY';
// NextBillion.ai Geofencing API base URL
const API_BASE_URL = 'https://api.nextbillion.io/geofence/contain';
// Function to check if a specific point is contained in one or more geofences
async function checkPointInGeofences(locations) {
try {
// Prepare the API endpoint with the API key and locations parameter
const apiEndpoint = `${API_BASE_URL}?key=${API_KEY}&locations=${locations}`;
// Make the API call to check if the locations are contained in the geofences
const response = await axios.get(apiEndpoint);
// Handle the API response
if (response.data.status === 'Ok') {
const result = response.data.data.result_list;
if (result.length === 0) {
console.log('No geofences contain the given locations.');
} else {
console.log('Geofences containing the locations:');
result.forEach((geofence) => {
console.log('Geofence ID:', geofence.id);
console.log('Geofence Name:', geofence.name);
// Add more information you want to display for each geofence
// Perform automatic dispatching action here
dispatchFieldTechnician(geofence);
});
}
} else {
console.log('Error checking geofence containment:', response.data.status);
}
} catch (error) {
console.error('An error occurred:', error.message);
}
}
// Function to dispatch a field technician to a geofence location
function dispatchFieldTechnician(geofence) {
// Replace this with your actual implementation of automatic dispatching
// For this example, we will simply log a message indicating the dispatching action.
console.log(`Dispatching field technician to Geofence ID: ${geofence.id}`);
console.log(`Field Technician dispatched to: ${geofence.name}`);
// You can add more actions here, such as sending notifications, updating the database, etc.
}
// Call the function to check if the locations are contained in the geofences
// Replace 'LOCATION_COORDINATES' with the actual pipe-separated coordinates in [latitude,longitude] format
// Example: '13.25805884388484,77.91083661048299|13.25805884388484,77.91083661048299'
checkPointInGeofences('LOCATION_COORDINATES');
Ensure that you replace ‘YOUR_API_KEY’ with your actual NextBillion.ai API key, and ‘LOCATION_COORDINATES’ with the actual pipe-separated coordinates in [latitude,longitude] format of the location you want to check against the geofences.
The `checkPointInGeofences` function sends a GET request to the API to check if the specified locations are contained in the provided geofences. The response will contain information about the geofences that contain the given locations.
The `dispatchFieldTechnician(geofence)` function performs an automatic dispatch function for field technicians if a location coordinate is found within a geofence.
Please note that this is a basic example, and you can integrate this logic into your existing dispatch system or build a more comprehensive automation process as per your specific use case and requirements. Additionally, consider implementing proper error handling and logging to handle different scenarios effectively.
