We would like to create a new Post REST API operation in Jupyterhub. Looking for guidance and/or documentation on how to implement a new Jupyterhub REST API.
Have you looked at JupyterHub services? Services — JupyterHub 1.4.2 documentation
I looked at that documentation. But not making the connection to how to go about adding a new REST API to Jupyterhub. Please advise.
Are you talking about proposing a change to JupyterHub itself? JupyterHub’s API endpoints are defined in jupyterhub.apihandlers.
If you are talking about adding REST endpoints for your own deployment, this should be done as a separate service, following the docs @manics linked. We have a few examples of services exposing API endpoints. For example this one using FastAPI.
