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:

https://www.nirmata.io/api/

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 (https://www.getpostman.com/), to try and learn the API.

Authentication

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

Authorization BASIC <Bas64 user:password>

or:

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.

Operations
Operation HTTP Method URI Syntax Description
Create POST /{modelIndex} Creates a new resource. The modelIndex is the resource name.
/{parent}/{id}/{relation} Create a new resource, as child of the ‘{parent}/{id}’ resource
Retrieve GET /{modelIndex} Returns all resources of type specified by ‘modelIndex’
/{modelIndex}/{id} Returns a single resource
Update PUT /{modelIndex}/{id} Updates a resource
Delete DELETE /{modelIndex}/{id} Deletes a resource
Discover OPTIONS / Returns the class definitions for all resources
/{modelIndex} Returns the class definition for a single resource
HTTP Response Status Codes

The following table lists common HTTP response codes used by the API:

HTTP Status Code Description
200 The operation succeeded
401 The user authentication failed
403 The request was not permitted
406 The request results in an invalid configuration
500 The request caused a server error
