REST API Developer's Guide

Add Device Properties

You can use LogicMonitor's REST API to programmatically add device properties. You can do this one of two ways:

  1. using the PATCH method with the devices resource - you can use PATCH to update only the customProperties object for a device, and you can use the opType parameter to add or update a single property within this object.
  2. by making a POST request to the device properties resource

Note: As with all of our API calls, authentication is required.


Add a property via the device properties resource


Resource URI: /device/devices/{deviceID}/properties

Where deviceID is the ID of the device you want to add a property to.

Resource Properties: You can POST the following parameters for each property:




name The name of the property String
value The value of the property String




The following Python script adds a property 'prodDC' with value 'LA' to device 4374:

#!/bin/env python

import requests
import json
import hashlib
import base64
import time
import hmac

#Account Info
AccessId ='48v2wRzfK94y53sq5EuF'
AccessKey ='H_D9i(f5~B^U36^K6i42=^nS~e75gy382Bf6{)P+'
Company = 'api'

Request Info
httpVerb ='POST'
resourcePath = '/device/devices/4374/properties'
queryParams =''
data = '{"name":"prodDC","value":"LA"}'

#Construct URL 
url = 'https://'+ Company +'' + resourcePath + queryParams

#Get current time in milliseconds
epoch = str(int(time.time() * 1000))

#Concatenate Request details
requestVars = httpVerb + epoch + data + resourcePath

#Construct signature
signature = base64.b64encode(,msg=requestVars,digestmod=hashlib.sha256).hexdigest())

#Construct headers
auth = 'LMv1 ' + AccessId + ':' + signature + ':' + epoch
headers = {'Content-Type':'application/json','Authorization':auth}

#Make request
response =, data=data, headers=headers)

#Print status and body of response
print 'Response Status:',response.status_code
print 'Response Body:',response.content
