You cannot modify this deployment process because it is frozen

You’ll need to create a new deployment process instead.
Is it even possible to create a new one if there is no API POST method for that? https://github.com/OctopusDeploy/OctopusDeploy-Api/wiki/DeploymentProcesses

Hi,

Thanks for getting in touch! You can update a deployment process that is not frozen. This means that you can update a deployment process that belongs to a project. You can think about it as the most recent version of the deployment process. All other versions belong to releases.

POST request should work just fine. You can verify that by opening dev tools in your browser and updating a deployment process in one of your projects. You will see that the UI sends a POST request.

Is there anything specific you are trying to achieve?

Please let me know how you go.

Regards,

Pawel
