API Basics

The Nirmata API model is composed of resources. Each resource type is described by a class and is made up of attributes and relations. Each resource has a modelIndex that indicates its class, and a uri that describes how it can be queried. At runtime, each resource can contain relations to other resources. The relations can be parent-child relations or reference relations.

The Nirmata API is accessible at:


Note: trying the API URL in a browser will return an empty page, as the required HTTP headers are not specified. You can use a REST client, like Postman (http://www.getpostman.com/), to try and learn the API.


To authenticate your account, you can use HTTP BASIC authentication or an API Key:

Authorization BASIC <Bas64 user:password>


Authorization NIRMATA-API <your api key>

Since the Nirmata API is only accessible via HTTPS, your credentials are sent over an encrypted connection.

To manage your API Key, login to Nirmata and navigate to Settings -> Account -> Generate API Key. An API key is associated with a User account. When you authenticate an application using the API key, it will get the role and privileges associated with the account.

A best practice recommendation is to create separate accounts for each application, and provide the minimum required role and privileges to the account.
