The Lightstep Observability API is now available as a collection in Postman. A full list of available Lightstep Observability API calls is structured by folder in the left pane of Postman.

Note: The following section is required for the API calls to work.

Setup API keys in Postman

The collection uses Postman Environment variables to set API keys and other values that might remain static most of the time, for example organization and project.

Follow these steps to setup your API keys for your collection.

  1. Click the Manage Environments gear icon in the upper right corner of Postman.
  2. Click Add and enter an Environment Name. For example, you can name your environment Lightstep or Lightstep-YourOrgName.
  3. In the table, add the variable lightstep_api_key. In the Current Value column, enter your actual LightStep API Key.
  4. If you have access to multiple organizations and projects, you can also choose to add the organization or project variables and/or setup multiple environments.
  5. Once an Environment is set up, you can choose it from the dropdown in the upper right corner of Postman.

Use the Collection

After setup is complete, you are ready to begin making API calls. In the Lightstep Observability Public API collection in the left sidebar, there are multiple subfolders for each type of API category listed in the Lightstep Public API Reference. You can test your API access by using the API calls under the Test folder.
