Get all organizations in Azure DevOps using REST API

If you load the current landing page, it displays all your organizations tied to your account. I assumed it had to get that information some way. I captured the network traffic and I believe you could get to the data you want using a system API call. However, it might change or might become unsupported without notice, so use at your own discretion.

You can get the information you want using this API:

Post https://dev.azure.com/{organization1}/_apis/Contribution/HierarchyQuery?api-version=5.0-preview.1

Body:

{    "contributionIds": ["ms.vss-features.my-organizations-data-provider"],    "dataProviderContext":        {            "properties":{}        }}

Response:

{    "dataProviderSharedData": {},    "dataProviders": {        "ms.vss-web.component-data": {},        "ms.vss-web.shared-data": null,        "ms.vss-features.my-organizations-data-provider": {            "organizations": [                {                    "id": "{redacted id}",                    "name": "{organization1}",                    "url": "https://{organization1}.visualstudio.com/"                },                {                    "id": "{redacted id}",                    "name": "{organization2}",                    "url": "https://dev.azure.com/{organization2}/"                }            ],            "createNewOrgUrl": "https://app.vsaex.visualstudio.com/go/signup?account=true"        }    } }

you can do it simply by making a call to get all the account you are member/ owner of. However for that you need your id, which can be easily fetched by making get profile call. Here are steps below:

1. Make a VSTS API call to get profile details using Bearer token or PAT

https://app.vssps.visualstudio.com/_apis/profile/profiles/me?api-version=5.1

This will return you, your Id:

{    "displayName": "xxxx",    "publicAlias": "xxx",    "emailAddress": "xxx",    "coreRevision": xxx,    "timeStamp": "2019-06-17T09:29:11.1917804+00:00",    "id": "{{We need this}}",    "revision": 298459751}

2. Next, make a call to get all the accounts you are member of or owner of:

https://app.vssps.visualstudio.com/_apis/accounts?api-version=5.1&memberId={{Your Id}}

Response:

{    "count": 1,    "value": [        {            "accountId": "xxx",            "accountUri": "xxx",            "accountName": "xxx",            "properties": {}        }    ]}

It will return list of accounts you are associated with.

A REST API request/response pair can be separated into five components:

The request URI, in the following form:

VERB https://{instance}[/{team-project}]/_apis[/{area}]/{resource}?api-version={version}

instance: The Azure DevOps Services organization or TFS server you're sending the request to.

They are structured as follows:Azure DevOps Services: dev.azure.com/{organization}

The REST API's are organization specific. This is not documented at present. You could submit a feature request here: https://developercommunity.visualstudio.com/spaces/21/index.html

Our PM and product team will kindly review your suggestion. Sorry for any inconvenience.

As a workaround, you could use the API which captured from network traffic just as Matt mentioned.
