Octopus as an API-First Application
Architecturally, Octopus Deploy is built API-first. This means that Octopus is built in layers - all data and operations are available over its REST API. The Octopus Web Portal (the main Octopus UI) is actually built on top of this API. In the Octopus Web Portal, we don't use any shortcuts - 100% of the data and operations that you can see and perform in the Octopus UI can be performed over the REST API.
The Octopus REST API is designed:
- To be friendly and easy to figure out.
- To be hypermedia driven, using links and the occasional URI template (read more).
- To be comprehensive - 100% of the actions that you perform via the Octopus UI can be performed via the API.
- To have a nice client library for .NET available via NuGet.
If you plan to use the REST API from C# or another .NET project, see the Octopus.Client assembly.
REST API Documentation via Swagger
As of Octopus 3.17, Octopus now includes the default Swagger UI for displaying the API documentation in a nice human readable way. To browse that UI just open your browser and go to
[OctopusServerURL]/swaggerui/. The original Non-Swagger API page is still available and can always be accessed via
You can view the API through the Octopus Demo server at demo.octopus.com/swaggerui/index.html.
API and Spaces
Spaces was introduced in Octopus 2019.1. If you are using spaces, you need to include the
SpaceID in your API calls. If you do not include the
SpaceID, your API calls will automatically use the default space.
