Is there a way to manually send an event to a notification pipeline from within a python script? I am basically looking for a programmatic way to test a pipeline similar to how you can test one from the gateway webpage.
Technically, yes. In practice, not easily; it would require reaching deep into internal classes that are subject to change between versions.
That was my guess. I thought I might be able to find something starting with the context variable. But it sounds like this would be better done with a clever manipulation of tags.
