Get access token using Azure CLI or Azure PowerShell

In this article, you'll learn how to obtain an access token for the FHIR service and the DICOM service using PowerShell and the Azure CLI. Keep in mind that in order to access the FHIR service or the DICOM service, users and applications must be granted permissions through role assignments from the Azure portal or using scripts. For more information about how to get started with Azure Health Data Services, see How to get started with FHIR or How to get started with DICOM.

Obtain and use an access token for the FHIR service

The FHIR service uses a specific resource or Audience with URI equal to the URI of the FHIR server https://<workspacename-fhirservicename>.azurehealthcareapis.com. You can obtain a token and store it in a variable (named $token) with the following command:

Azure CLI

token=$(az account get-access-token --resource=https://<workspacename-fhirservicename>.azurehealthcareapis.com --query accessToken --output tsv)
curl -X GET --header "Authorization: Bearer $token" https://<workspacename-fhirservicename>.azurehealthcareapis.com/Patient

Azure PowerShell

$token = (Get-AzAccessToken -ResourceUrl 'https://<workspacename-fhirservicename>.azurehealthcareapis.com').Token
$headers = @{Authorization="Bearer $token"}
Invoke-WebRequest -Method GET -Headers $headers -Uri 'https://<workspacename-fhirservicename>.azurehealthcareapis.com/Patient'

Obtain and use an access token for the DICOM service

The DICOM service uses the same resource or Audience with URI equal to https://dicom.healthcareapis.azure.com to obtain an access token. You can obtain a token and store it in a variable (named $token) with the following command:

Azure CLI

$token=$(az account get-access-token --resource=https://dicom.healthcareapis.azure.com --query accessToken --output tsv)
curl -X GET --header "Authorization: Bearer $token"  https://<workspacename-dicomservicename>.dicom.azurehealthcareapis.com/v<version of REST API>/changefeed

Azure PowerShell

$token = (Get-AzAccessToken -ResourceUrl 'https://dicom.healthcareapis.azure.com').Token
$headers = @{Authorization="Bearer $token"}
Invoke-WebRequest -Method GET -Headers $headers -Uri 'https://<workspacename-dicomservicename>.dicom.azurehealthcareapis.com/v<version of REST API>/changefeed'
