Governance REST API

The Governance REST API is one of many APIs supported by WSO2 Governance Registry. Read more on Supported APIs and Standards for a complete list of APIs supported by WSO2 Governance Registry.

The Governance REST API basically facilitates the capability to perform the CRUD operations via the well-defined HTTP protocol. The REST API uses the GET, POST, PUT, and DELETE operations of the well-defined HTTP protocol to do the CRUD operation via any REST Client. Google Chrome's Advanced REST client is one of the client tools used to test the functionality of the Governance REST API.

The Governance REST API is secured with Basic Auth access token. You can invoke the rest API with Basic Auth header
Authorization: Basic YWRtaW46YWRtaW4= where the format is Authorization: Basic {base64encoded(username:password)} 


At the moment REST API only supports configurable governance artifacts. Support for Content artifacts such as WSDL and Policy are limited. Future versions of REST API will equally support both types of artifacts.  

Security Requirements

You must send valid HTTP BasicAuth credentials when invoking the REST API.

 

See the sections below for information relating to invoking the REST API after generating the access token and some sample requests and complete URI formats:

 

Assets

  1. Get list of available artifact types

    Syntax - GET  /governance/types/
    Example - GET https://localhost:9443/governance/types/
  2. Get list of assets of certain type

    Syntax -
    GET  /governance/<asset_short_name_s>

    GET  /governance/<asset_short_name_s>?query 

    Supported query format:

    • xyz  - Looks for artifacts with name xyz

      • You can give only the value like above or give the field name and the value in a key-value pair for fields of the Overview table in the asset RXT file. (e.g. name=xyz)
      • However, to find assets with a specific value for a field in a table other than the Overview table, the search query should be:
        encode(table_name:field_name)=encode(value)
        For example, if the table is docLinks, the field is documentType and the value is 'the rest1'. The final URI query parameter should be: docLinks%3AdocumentType=the%20rest1
      • If you have spaces or any special characters such as underscore or slash in the key of the key-value pair of your query URL, you need to encode it using a URL encoder.

    • xyz&version=1.3.5 - Looks for artifacts with name xyz with version 1.3.5

    • tags=abc - Searches artifacts with tag 'abc'

    • lcState=development&lcName=ServiceLifeCycle - Searches artifacts with an associated life cycle name ServiceLifeCycle with state 'development'

    • country=usa - Looks for all the artifacts having attribute country with value 'usa'. This internally handles whether country is an rxt attribute or a property.

    • version=1.3.5&mediaType=application/vnd.wso2-soap-service+xml - searches only soap services with version 1.3.5 

    Examples -

    GET https://localhost:9443/governance/restservices
    GET https://localhost:9443/governance/restservices?name=restservice1

    GET https://localhost:9443/governance/restservices?name=restservice1&version=1.0.0
    GET https://localhost:9443/governance/restservices?docLinks%3AdocumentComment=rest1%20is%20a%20simple%20API 

    WSO2 G-Reg does not support date range searches in Governance REST API.

  3. Get an individual asset of certain type

    Syntax - GET  /governance/<asset_short_name_s>/UUID  
    Example - GET  https://localhost:9443/governance/restservices/3245se24553 
  4. Create a new asset

    Syntax - POST  /governance/<asset_short_name_s>   <payload>

    Here the payload should be in JSON format. Following are the required attributes.
    • name
    • version
    • type

    Payload format is as follows:

    {
name: "Artifact Name",
type: "Artifact Type",
version: “Version Number",
Attribute-N: “Attribute-N” value
} 

    If the artifact creation is successful, the server will return HTTP 200 code along with the “location” header pointing to the newly created artifact. If there is an issue creating a new artifact, it will return an appropriate error code.  

    Example -

    POST  https://localhost:9443/governance/restservices      

    {

    name: "TestRESTService",

    type: "restservice",

    context: "/test",

    version: "1.0.0"

    }

    This may return the following:

    HTTP 200

    Location: https://localhost:9443/governance/restservices/3ec1dcd9-66d8-41da-a0d2-ec171df64cc3

  5. Update an existing asset

    Syntax - PUT /governance /<asset_short_name_s>/uuid   <payload>

    Here the payload should be in JSON format. Following are the required attributes.
    • name
    • version
    • type

    Payload format is as follows: 

     {
name: "Artifact Name",
type: "Artifact Type",
version: “Version Number",
Attribute-N: “Attribute-N” value
}

    If the artifact creation is successful, the server will return HTTP 201 code along with the “location” header pointing to the newly created artifact. If there is an issue creating the new artifact, it will return an appropriate error code.

    Example -

    PUT  https://localhost:9443/governance/restservices/324dsdwa535   

    {

    name: "TestRESTService",

    type: "restservice",

    context: "/test-new",

    version: "1.0.0",

    }

  6. Delete an asset
    Syntax - DELETE  /governance/<asset_short_name_s>/UUID
    Example - DELETE  https://localhost:9443/governance/restservices/3245se24553
  7. Get lifecycle state of an asset

    Syntax - 
    GET  /governance/<RXT_short_name_s>/uuid/states 
    GET  /governance/<RXT_short_name_s>/uuid/states?lc=LCName

    Examples - 
    GET  https://localhost:9443/governance/restservices/44dadw4/states
    GET  https://localhost:9443/governance/restservices/44dadw4/states?lc=ServiceLifeCycle
  8. Update lifecycle change of an asset

    Syntax -

    PUT  /governance/<RXT_short_name_s>/uuid/states    payload 

    Payload format

    {

    lc: "Lifecycle name",

    action: "Promote",

    check_item_N : "value_N",

    }

    Example -

    PUT https://localhost:9443/governance/restservices/cea0c482-4280-4837-8126-3fd97cdc0a41/states

    {
    lc: "ServiceLifeCycle",

    action: "Promote",

    item_0 : "true",

    item_1 : "true",

    item_2 : "true"

    } 

Endpoints

  1. Get all endpoints

    Syntax - GET /governance/endpoints

    Example - GET https://localhost:9443/governance/endpoints

  2. Get an individual endpoint

    Syntax  -  GET  /governance/endpoints/UUID    
    Example - GET https://localhost:9443/governance/endpoints/c7d6ed67-f2f5-409f-97f2-ddff9b6bc07b 
  3. Create new endpoint 

    Syntax - POST /governance/endpoints <payload> 

    Here the payload should be in JSON format.Following are the required attributes:
    • name
    • version
    • type

    Payload format is as follows:

    {
name: "Artifact Name",
type: "endpoint",
version: “Version Number",
Attribute-N: “Attribute-N” value
}

    If the artifact creation is successful, the server will return HTTP 201 code along with the “location” header pointing to the newly created artifact. If there is an issue creating the new artifact, it will return an appropriate error code.  

    Example -

    POST  https://localhost:9443/governance/endpoints/ 

    {

    name: "endpoint-1",

    type: "endpoint",

    version: "1.0.0",
