Lookup API
You can use this endpoint to upload files that can be used by the
lookup()
and match()
functions.
You can upload files in CSV or JSON format. Upload files as multipart form
data. The file should be in a part named
file
.
Files can be uploaded to a repository or files can be uploaded as shared
files that are available in all repositories. Shared files are visible in
all repositories and can be used by all users. Only root users can upload,
delete and edit shared files. shared files are referenced from functions
like lookup()
and match()
, by
filename preprended with /shared/
. For example
/shared/myfile.csv
The endpoints displayed on this page are deprecated starting with version 1.27 of Humio. Users are encouraged to use instead the corresponding queries and mutations provided by our GraphQL.
Example: Using curl to Upload a File to a Repository
Replace myfile.csv
with the path
to your file (where $YOUR_LOGSCALE_URL
is the URL for
your Humio Cloud Account.
curl https://`$YOUR_LOGSCALE_URL`/api/v1/repositories/$REPOSITORY_NAME/files \
-H "Authorization: Bearer $API_TOKEN" \
-F "file=@myfile.csv"

The file can be deleted using:
curl -X DELETE https://`$YOUR_LOGSCALE_URL`/api/v1/uploadedfiles/shared/myfile.csv \
-H "Authorization: Bearer $API_TOKEN"
