There are 2 endpoints that seem to return extractions which are data/transforms/extractions and data/props/extractions. I've created some extractions that don't appear in the list when I hit these endpoints. I can only get an extraction in the list by setting the "Apply to" field to host from the dropdown in the UI. Does anyone have any insight as to why the extraction has to be applied to a host for it to show up in endpoint output?
It should be there. I tried to search an field extraction which is tagged to a sourcetype and the REST API returns result.
| rest /services/data/props/extractions | search title="<NAME_OF_YOUR_FIELD_EXTRACTON>"
How can anybody help you without more detail? The answer that I provided absolutely works unless you do not have privilege/permission to access the endpoint, which is probably the case.
