How to post Geofences Massively

Geofences can be uploaded massively with cURL.

1. Define a geofence with the following fields in JSON:

{
  "geometry": {
    "type": "Circle",
    "radius": 105,
    "coordinates": [
      -82.28900,
      24.78238
    ]
  },
  "properties": {
    "name": "warehouse 234",
    "visibility": "groups",
    "groups": [
      500
    ],
    "custom": {
      "foo": "bar",
      "something": true
    },
    "types": [],
    "description": "this is a sample description"<
  }
}

The main fields here are:
a. Geometry: specifies the Geometry type you want to create, the API supports:

• Polygon of 3 or more coordinates (up to 800 coordinates),
• Circle, or
• LineString types.

Polygon
geometry.coordinates = [[[lon1,lat1] ,[lon2,lat2],[lon3,lat3], [lon1,lat1]]]
Keep in mind that for Polygon types the last lon,lat pair has to be equal to the first, this tells the API that it’s closed at that point.

Circle
geometry.radius = radius in meters (minimum 50 meters)
geometry.coordinates = [lon,lat]

LineString
geometry.radius = radius in meters
geometry.coordinates = [[lon1,lat1],[lon2,lat2]]

when creating geofences you can specify custom properties using the custom key in the properties. This accepts any JSON object value.

The visibility of the geofences are as follow:

If you set the visibility to “groups” you’ll have to specify in an array called: groups the group IDs you’d like this geofence to belong to.

2. Create a post for each geofence to create:

curl -X POST 
--header 'Content-Type: application/json' --header "Authenticate: 597015be528ff39fed5c2fefe8ce1ea9b895df6ac71bee05d52a6d5e" 
--data '{"geometry": {"type": "Circle","radius": 105,"coordinates": [-82.28900,24.78238]},"properties": {"name": "warehouse 234","visibility": "groups","groups": [500],"custom": {"foo": "bar","something": true},"types": [],"description": "this is a sample description"}}' 
'https://pegasus1.pegasusgateway.com/api/geofences' 

3. Create an script with the cURLs you have just generated:

#!/bin/bash
for i in $(seq 1 1);
do

curl -X POST 
--header 'Content-Type: application/json' --header "Authenticate: 597015be528ff39fed5c2fefe8ce1ea9b895df6ac71bee05d52a6d5e" 
--data '{"geometry": {"type": "Circle","radius": 105,"coordinates": [-81.28900,22.78238]},"properties": {"name": "warehouse 234","visibility": "groups","groups": [500],"custom": {"foo": "bar","something": true},"types": [],"description": "this is a sample description"}}' 
'https://pegasus1.pegasusgateway.com/api/geofences' 

curl -X POST 
--header 'Content-Type: application/json' --header "Authenticate: 597015be528ff39fed5c2fefe8ce1ea9b895df6ac71bee05d52a6d5e" 
--data '{"geometry": {"type": "Circle","radius": 105,"coordinates": [-8.5847,25.88954]},"properties": {"name": "test 567","visibility": "groups","groups": [500],"custom": {"foo": "bar","something": true},"types": [],"description": "this is a sample description"}}' 
'https://pegasus1.pegasusgateway.com/api/geofences' 

done

4. Run the script for Bash (This is a Linux app, but there is a bash application in Windows store as well)
