Resource URL

https://host:port/ibmmq/rest/v3/admin/installation/{installationName}

installationName: Optionally specifies the name of the installation to query. This name must be the name of the installation that the REST API is running in.

You can use HTTP instead of HTTPS if you enable HTTP connections. For more information about enabling HTTP, see Configuring HTTP and HTTPS ports.

Optional query parameters

attributes={extended|*|extended.attributeName,...}

extended

Specifies that all extended attributes are returned.

*

Specifies all attributes. This parameter is equivalent to extended.

extended.attributeName,...

Specifies a comma-separated list of extended attributes to return:

level: String.; IBM® MQ build level.
operatingSystem: This attribute is only available on z/OS®, AIX®, Linux®, and Windows.; String.; Full descriptive text of the operating system.
description: This attribute is only available on AIX, Linux, and Windows.; String.; Installation description.
installationPath: This attribute is only available on AIX, Linux, and Windows.; String.; The path to the installation.
dataPath: This attribute is only available on AIX, Linux, and Windows.; String.; The path to where the data for the installation is stored.
maximumCommandLevel: This attribute is only available on the IBM MQ Appliance, AIX, Linux, and Windows.; Integer.; Maximum command level that is supported.
primary: This attribute is only available on AIX, Linux, and Windows.; Boolean.; Primary installation status.

Request headers

The following headers must be sent with the request:

Authorization: This header must be sent if you are using basic authentication. For more information, see Using HTTP basic authentication with the REST API.

Request body format

None.

Security requirements

The caller must be authenticated to the mqweb server and must be a member of one or more of the MQWebAdmin, MQWebAdminRO, or MQWebUser roles. For more information about security for the administrative REST API, see IBM MQ Console and REST API security.

If token based security is used, the LTPA token that is used to authenticate the user must be provided with the request as a cookie. For more information about token-based authentication, see Using token-based authentication with the REST API.

There are no specific authorization requirements for an HTTP GET on the installation resource.

Response status codes

200: Installation information retrieved successfully.
400: Invalid data provided.; For example, invalid installation attributes specified.
401: Not authenticated.; The caller must be authenticated to the mqweb server and must be a member of one or more of the MQWebAdmin, MQWebAdminRO, or MQWebUser roles. For more information, see Security requirements.
404: Installation does not exist.
500: Server issue or error code from IBM MQ.

Response headers

The following headers are returned with the response:

Content-Type: This header is returned with a value of application/json;charset=utf-8.

Response body format

The response is in JSON format in UTF-8 encoding. The response contains an outer JSON object that contains a single JSON array called installation. Each element in the array is a JSON object that represents information about an installation. Each JSON object contains the following attributes:

name

This attribute is only available on AIX, Linux, and Windows.

String.

The installation name.

version

String.

The version of IBM MQ for the installation.

platform

String.

One of the following values:

appliance
ibm-i
unix
windows
z/os

extended

JSON object.

If requested, contains one or more of the following extra properties:

level: String.; IBM MQ build level.
operatingSystem: This attribute is only available on z/OS, AIX, Linux, and Windows.; String.; Full descriptive text of the operating system.
description: This attribute is only available on AIX, Linux, and Windows.; String.; Installation description.
installationPath: This attribute is only available on AIX, Linux, and Windows.; String.; The path to the installation.
dataPath: This attribute is only available on AIX, Linux, and Windows.; String.; The path to where the data for the installation is stored.
maximumCommandLevel: This attribute is only available on the IBM MQ Appliance, AIX, Linux, and Windows.; Integer.; Maximum command level that is supported.
primary: This attribute is only available on AIX, Linux, and Windows.; Boolean.; Primary installation status.

If an error occurs, the response body contains an error message. For more information, see REST API error handling.

Examples for AIX, Linux, and Windows

The following example gets basic information about the installation that the REST API is running in. The following URL is used with the HTTP GET method:
```
https://localhost:9443/ibmmq/rest/v3/admin/installation
```
The following JSON response is returned:
```
{
    "installation": 
    [{
       "name": "Installation1",
       "platform": "windows",
       "version": "9.1.0.0"
    }]
}
```

The following example gets extended information about the installation Installation1. The following URL is used with the HTTP GET method:

The following JSON response is returned:

{
    "installation": 
    [{
         "extended": {

    }]
}

The following example gets the installation path for Installation1. The following URL is used with the HTTP GET method:

https://localhost:9443/ibmmq/rest/v3/admin/installation/Installation1?attributes=extended.installationPath

The following JSON response is returned:

{
    "installation": [{
        "extended": {
             "installationPath": "C:\\Program Files\\IBM\\MQ"
