Canceling a Durable Function
Explore how to cancel long-running Azure Durable Functions using built-in HTTP trigger URLs and custom logic in .NET. Understand terminating single or multiple orchestrator instances and key considerations for managing active workflows and message queues.

As with any long-running tasks, sometimes there is a need to cancel a durable function. There are multiple ways to do it, which we will cover in this lesson. We will use the interactive playground below, which has a long-running durable function and multiple HTTP trigger functions with the termination functionality.

Durable function with termination tasks
Built-in termination process
The simplest way to cancel a durable function is to send a request to the special URL that is provided to us in the response from the HTTP trigger that starts the orchestrator. An example of such a response can be found below:
There are several URLs provided in this response and all of them represent a functionality specific to the orchestrator instance that we trigger in the code snippet above. Here is the full list:
