Welcome to the VIKTOR API documentation.

What is an API?

An API, or Application Programming Interface, acts as a communication gateway between different software applications. It defines the rules and tools for building software and allows developers to access the functionality of a system, service, or platform. In simpler terms, an API enables interaction and data exchange between software components.

When to Use?

The API provides a standardized interface to access specific features of the VIKTOR platform. Our API can be used to extract or modify data from your environment, integrate apps into your own software and workflows or automate tasks. When accessing the VIKTOR in the browser, using the API is not required as the functionality is directly available through the user interface. If you want to exchange data with the VIKTOR platform by means of code you can use the API.


VIKTOR provides both a low-level REST API, and an API module as part of the SDK.

The REST API is the foundation for interaction and data exchange with the VIKTOR platform. Developers can use it to access app or organizational resources through HTTP requests. The REST API is programming-language agnostic and can be accessed by all popular programming languages such as Python, Javascript, Go(lang), Ruby, C#, etc.

The VIKTOR SDK API is built on top of the REST API and provides access to many of the relevant requests through an even developer-friendlier Python interface. The SDK API takes care of more complicated parts such as 'pagination', 'filtering by reference', and 'object serialization'. We therefore strongly recommend using the SDK API wherever possible.
