@atripp I must be missing something obvious then. Can you please point me to the API documentation which covers deleting packages? In https://docs.inedo.com/docs/proget/reference/api, I see only:

• Package Promotion API - does not cover deletion
• Webhook Management API - not relevant
• Asset Directory API - not relevant
• Feed Management API - only covers deleting entire feeds, not packages
• Connector Health API - not relevant
• Package Deployment API - only covers deploying packages, not deleting them
• Security Management API - not relevant

I cannot find any way to delete individual packages with the ProGet REST API, or am I mistaken?

The problem is, ProGet's retention policies are too limited for our use-case and we will need to write something ourselves. But it only seems that we can delete an entire feed with the API, and not individual packages (or groups). Is it really not possible to delete a group or individual package from the API?
