Signals API

The Signals API accepts a set of signals, encoded as JSON objects, for indexing into a signals collection.

Note
 This API requires a Fusion AI license.

Normally, signals are indexed just like ordinary documents, through a configured datasource and index pipeline. This API is provided for cases where it is more convenient to index signals directly.

To aggregate signals, use a SQL aggregation job, which is a kind of Spark job.

Tip
 You can manage aggregation jobs in the Jobs manager and Scheduler in the Admin UI, or with the Spark jobs API. We recommend using the Admin UI.

See Signal types and structure to learn how to send well-formed signals to this API.

Examples

Send two signal events to record user clicks:

REQUEST

curl \
 -u user:pass -X POST -H 'Content-type:application/json' -d @- \

A successful request results in events being added to the signals collection. For the above example, the events will be represented as follows:

  "responseHeader":{

    "QTime":1,
    "params":{
      "indent":"true",
      "q":"docId: 2125233",
