Access DICOMweb APIs with the DICOM service

The DICOM® service allows you to store, review, search, and delete DICOM objects by using a subset of DICOMweb APIs, which are web-based services that follow the DICOM standard. By using these APIs, you can access and manage your organization's DICOM data in the cloud without requiring complex protocols or formats.

The supported services are:

In addition to the subset of DICOMweb APIs, the DICOM service supports two custom APIs that are unique to Microsoft:


  • Deploy an instance of the DICOM service. For more information, see Deploy the DICOM service using Azure portal.

  • Find your Service URL. Use Azure portal to navigate to the instance of the DICOM service to find the Service URL. The Service URL to access your DICOM service uses this format: https://<workspacename-dicomservicename> Make sure to specify the version as part of the URL when making requests. For more information, see API versioning for the DICOM service.

Use REST API methods to interact with the DICOM service

The DICOM service provides a web-based interface that follows REST (representational state transfer) principles. The REST API allows different applications or systems to communicate with each other using standard methods like GET, POST, PUT, and DELETE. Use any programming language that supports HTTP requests and responses to interact with the DICOM service.

For language-specific examples, refer to the examples. You can view Postman collection examples in several languages including:

  • Go
  • Java
  • JavaScript
  • C#
  • PHP
  • C
  • NodeJS
  • Objective-C
  • OCaml
  • PowerShell
  • Python
  • Ruby
  • Swift


Refer to Use DICOMweb Standard APIs with C# to learn how to use C# with DICOM service.


cURL is a common command-line tool for calling web endpoints and is available for most operating systems. To get started, download cURL.

To learn how to use cURL with DICOM service, see Using DICOMWeb™ Standard APIs with cURL tutorial.


Refer to the Using DICOMWeb™ Standard APIs with Python tutorial to learn how to use Python with the DICOM service.


Postman is an excellent tool for designing, building, and testing REST APIs. Download Postman to get started. Learn how to use Postman at the Postman learning site.

One important caveat with Postman and the DICOMweb Standard is that Postman only supports uploading DICOM files using the single part payload defined in the DICOM standard. This reason is because Postman can't support custom separators in a multipart/related POST request. For more information, see Multipart POST not working for me # 576. All examples in the Postman collection for uploading DICOM documents using a multipart request are prefixed with [won't work - see description]. The examples for uploading using a single-part request are included in the collection and are prefixed with Store-Single-Instance.

To use the Postman collection, you need to download the collection locally and import the collection through Postman. To access this collection, see Postman Collection Examples.
