REST Service Specifications v2.0

The REST service provides an API consisting of a set of HTTP endpoints(methods) with the ability to create, retrieve, edit, or delete access to information stored in a NEXUS IC database. The REST service ensures all request are made through the NEXUS Storage engine which allows security and cohesion to be maintained and respected within the NEXUS database data.

Note

As of NEXUS version 6.9, REST Service Specifications v1.0 is no longer supported.

Components of a REST API request/response

  1. The request URI, which consists of: {uri scheme} :// {uri host} /icweb.dll/ {resource-path} ? {query-string}

    • URI scheme: Indicates the protocol used to transmit the request. This is either http or https. We highly recommend using https in your deployments.

    • URI host: Specifies the domain name or IP address of the server where the REST service endpoint is hosted, such as sample.nexusic.com

    • Resource path: Specifies the resource or resource collection, as detailed below in the API

    • Query string (optional): Provides additional parameters as required.

  2. HTTP request message header fields:

    • A required HTTP method (or verb), which tells NEXUS what type of operation you are requesting. The NEXUS REST service support GET, PUT, POST, and DELETE.

    • Optional additional header fields, as required by the specified URI and HTTP method. For example, an Authentication token that can be used for client authorization.

  3. An Optional HTTP request message body, to support the URI and HTTP operation. For POST or PUT operations, the request body is required to have a MIME-type of application/json.

  4. A HTTP status code, this may be from the 2xx, 4xx or 5xx codes. Each service will indicate what possible returns are available.

  5. Optional HTTP response message body, MIME-encoded response objects are returned in the HTTP response body, such as a response from a GET method that is returning data. All results are return in the format JSON.

Authentication

There are 3 authentication options available using Login:

  1. Username/password request

  2. API Key, that is associated with any user account with NEXUS, this provides permanent access until the API Key is changed in NEXUS

  3. Email based login, that provides the capability for the REST api to email a request token to the user, this is then used to have the REST api issue a token lasting 90 days.

All three of these authorization methods, issue a temporary HASH that expires 60 minutes after the last request.

Once the HASH is received from a valid authorization request to the server, this must be specified in subsequent requests via a query string parameter.

GET /icweb.dll/bo/?hash={value}
