openDCIM has a RESTful API interface which can be accessed by other applications.

Development of the API is happening in stages, and as such this specification is subject to change. If you are unfamiliar with what a RESTful API is, a good place to start is the Wikipedia Entry.

Data Format

openDCIM data will always be returned in JSON format, with no pagination. This is open source, so if you need your output in another format, such as XML, you can modify the appropriate function in the application.

The JSON data is returned in the following format:

{

error: true or false,

errorcode: 200, if operation was a success; other dependent upon reason for failure

resultsetname (Varies depending upon request)

[{ data }]

}

Authentication

RESTful APIs by definition are stateless, but do still need some form of authentication. It is suggested that you create a separate account for the API to use, rather than piggy-backing off of an existing user account.

At a minimum, the account created for the API must have Global Read Access. Working with the inner guts of openDCIM will certainly increase the risk of data corruption, so it's not something that should be opened up lightly. If an API call requires a Specific Permission and is called by an account that does not possess that permission, an error 400 will be returned.

Base URI

Depending on how you implement your website, this may vary, but most would take on the format of:

https://myurl/api/v1 (for Version 1 of the API)

All definitions listed below will assume that they are added on to the base URI. For example, to get a list of all devices, the full URI would be https://myurl/api/v1/devices

Conventions

When listing a URI for an API call, there may occasionally be a word with a leading colon (:). This indicates that it is a parameter to be passed within the URL.

Example :deviceid would be the indication to substitute the last portion of the URL with a valid DeviceID

Collections

Collections of data are defined by requests which may return more than a single entity. Below are the defined interfaces. All of these are read-only.

People

/people

Method GET

Parameters none

Specific Permission Required Contact Administrator

This URI will return a collection of all people defined within openDCIM. There is a corresponding Entity URL for retrieving a single entity.

/people/bydepartment/:departmentid

Method GET

Parameters departmentid

Specific Permission Required Contact Administrator

This URI will return a collection of all people (if any) that are members of the given department. Note that people can be members of multiple departments.

Data Centers

/datacenter

Method GET

Parameters none

Specific Permission Required none

This URI will return a collection of all data centers defined within openDCIM. There is a corresponding Entity URL for retrieving a single entity.

Cabinets

/cabinet

Method GET

Parameters none

Specific Permission Required none

This URI will return a collection of all cabinets defined within openDCIM. There is a corresponding Entity URL for retrieving a single entity.

/cabinet/bydc/:datacenterid

Method GET

Parameters DataCenterID

Specific Permission Required none

This URI will return a collection of all cabinets, if any, that are defined within openDCIM as belonging to the specified DataCenterID.

/cabinet/bydept/:departmentid

Method GET

Parameters DepartmentID

Specific Permission Required none

This URI will return a collection of all cabinets, if any, that are defined within openDCIM as belonging to the specified DepartmentID.

Devices

/device

Method GET

Parameters none

Specific Permission Required none

This URI will return a collection of all devices defined within openDCIM. There is a corresponding Entity URL for retrieving a single entity.

/device/byowner/:departmentid

Method GET

Parameters DepartmentID

Specific Permission Required none

This URI will return a collection of all devices, if any, that are defined within openDCIM as belonging to the specified DepartmentID.

/device/bydatacenter/:datacenterid

Method GET

Parameters DataCenterID

Specific Permission Required none

This URI will return a collection of all devices, if any, that are defined within openDCIM as belonging to the specified DataCenterID.

/device/bycabinet/:cabinetid

Method GET

Parameters CabinetID

Specific Permission Required none

This URI will return a collection of all devices, if any, that are defined within openDCIM as belonging to the specified CabinetID.

Elements

Elements are API requests where a single entity is acted upon. As these are always acting upon just one tuple of the database, some of the API calls may be for creating, updating, or deleting data.

People

/people/:personid

Method GET

Parameters personid

Specific Permission Required Contact Administrator

This URI will return a single row matching the specified personid if it exists within the database, or an error if not found.

Data Centers

/datacenter/:datacenterid

Method GET

Parameters datacenterid

Specific Permission Required none

This URI will return a single row matching the specified DataCenterID if it exists within the database, or an error 404 if not found.

Cabinets

/cabinet/:cabinetid

Method GET

Parameters CabinetID

Specific Permission Required none

This URI will return a single row matching the specified CabinetID if it exists within the database, or an error 404 if not found.

Devices

/device/:deviceid

Method GET

Parameters DeviceID

Specific Permission Required none

This URI will return a single row with the specified DeviceID as key it it exists within the database, or an error 404 if not found.
