HTTP Query

In addition to basic auth, we also support an HTTP query string with the format, &apikey=your-ingestion-key as well as a header token with the format apikey:your-ingestion-key. While we appreciate thoroughness, please do not use more than one method of authentication per request! There is also a maximum payload size of 10 MB.

Metadata

Meta is a field reserved for custom information associated with a log line. To add metadata to an API call, specify the meta field under the lines object. Metadata can be viewed inside that line's context.

WARNING: If inconsistent value types are used, that line's metadata, will not be parsed. For example, if a line is passed with a meta object, such as meta.myfield of type String, any subsequent lines with meta.myfield must have a String as the value type for meta.myfield.
