Accessing the LogicMonitor REST API with Postman and Bearer Token Authentication
This is a follow-up to the classic Kurt_Huffman post: Accessing the LogicMonitor REST API with Postman and LMv1 API Token Authentication | LogicMonitor - 5143 That post is still a treasure trove of good discussion. Definitely check it out if you haven't already! While there is passing mention that you can use bearer token auth in Postman, I figured I'd write up a dedicated post. Creating a bearer token With the addition of bearer tokens, we eliminate the need for a Base64 encoded HMAC signature – so we get rid of several steps for auth. No need for any pre-request script, yay! See this page for generating and using bearer tokens in LogicMonitor: https://www.logicmonitor.com/support/bearer-token We do have a section in the above page on using the bearer token with Postman, but I like setting up with environment variables for better reusability. Postman setup with bearer tokens Download and install Postman, or use http://postman.com Launch Postman and create a new collection that will be used for all LogicMonitor API requests. Create a new environment with the following variable. You just need one for the bearer token. You should set the type to 'secret' for sensitive credentials. url – https://<portalname>.logicmonitor.com/santaba/rest If you want to work with the LM Ingestion API, duplicate this environment and change the url to 'https://<portalname>.logicmonitor.com/rest' (without "santaba") bearer – secret – For the current value, be sure to prepend the token with "bearer " (with space) Should look like this: bearer lmb_xxx Create a request within the collection. A sample request is shown below with the necessary parameters configured. Set the environment for the request (from step 3) Set the HTTP method for the request Use {{url}} to pull the base URL from the environment variable. Add the resource path and any request parameters your API request may require. Add the following headers: Authorization: {{bearer}} X-version: 3 (for latest LM API version) POST, PUT, and PATCH requests only: if your request includes JSON data, be sure to select the Body tab and select raw JSON
Can I pull a specific system property in an API call?
Hi, I’m writing an API call that pulls only specific fields. I can get all the normal fields, but I want to get system.groups. System.groups is inside the systemProperties array of variables and I haven’t been able to figure out if I can pull it. I’m using: &fields=name,displayName,collectorDescription,hostStatus and want to add systemProperties[system.groups] but can’t find any syntax that will work. I’ve found examples on how to Filter on a property, but not how to just display it. Anyone know how I can do this? Thanks.How do I configure Postman AUthentication for API
HI, I’m relatively new to Postman and API calls but have a decent grasp on how they work. However, I can’t figure out how to handle the Authentication part within LM. I read through the various KB articles but didn’t find a step-by-step which is what I need for this one. I was able to grab my ID and Key from our portal, but I’m not sure where I put them in Postman. Do I create them as variables and then add them as parameters somehow? I made a Collection for LM, but when I edit it and go to the Authentication area, I’m not sure which item to choose as none seem to let me put in an ID and a Key. Can anyone help me with how I get this setup? Thanks.
