Top Geofencing & Boundaries APIs# Geofencing API
## About Geofencing APIs
Geofencing APIs allow an app to identify users whenever their device crosses a defined perimeter surrounding a location of interest, such as a hotel, which can allow the app to monitor users in the vicinity or provide a beneficial experience to nearby users.
## What is geofencing?
Geofencing involves defining a distance-based radius around a specific latitude and longitude for a duration of time and then defining a transition type (events that active the geofence such as a user entering or leaving the perimeter). Users within the geofence are identified through the GPS-based location data transmitted by their device. The location data is collected only after a user provides their consent and is monitored in a battery-efficient manner.
## How does geofencing work?
Geofence APIs are provided by third party services to allow app developers to easily integrate the functionality the geofence API provides into their application following a defined set of protocols, based on the coding language of the API (HTML, JavaScript, Python, etc.)
When the application is ready to start monitoring the geofence, a request is sent to the web address of the API to send data whenever a geofence event occurs. The app developer then decides what action should be taken for each geofence event, such as sending a notification to the user of the app’s services, automatic check-in, or simply monitor the number of users in the vicinity.
## Who is geofencing for?
Geofencing is particularly important to any business with a brick-and-mortar location that offers users an app to provide support or services, such as gyms, shopping malls, airports, and restaurants. Geofencing allows businesses to provide users enhanced services and can be used to increase the business’s brand or increase users’ loyalty through offerings such as location-based advertising or services such as loyalty points.
## Why is geofencing important?
Geofence APIs delegate the task of monitoring location data to the device’s default location service so that each application that would like to use a geofence doesn’t have to run location services in the background which can slow down the device.
## What you can expect from Geofence-APIs?
Geofence-APIs allow app developers to target users based on the location data provided by their devices.

US Zipcode, County, City, and State Boundaries API:
A simple & very fast API that will allow you to integrate multiple GeoJson US boundaries results into your apps and systems.
This API is designed to be used programatically for optimal performance. When using the MashApe UI for queries expect significant latency issues on large result sets!
IP Geolocation API allows developers to get geolocation information for a given IP address. Data points returned by this GeoIP API include city, state, province, country, continent, latitude, longitude, region, timezone, current time, organization, ISP, local currency, and country flags. This IP Location API can be used for content personalization, geotargeting, geofencing, ad targeting, digital rights management, form auto-completion, etc. With the free plan, you can make 15,000 IP lookup API calls per month. Paid plans are starting from $15 per month.
Tired of field testing your geolocation based mobile apps? Wish you could see how your app would work if a user is walking or driving around with it? Want an easy way to test your app in random areas (geofences), random streets? Use our REST APIs in your app. Code locally, test globally.
