POSTing Raw Events

Events can be sent directly to Seq via HTTP

In some situations it may be desirable to send events to Seq without using a logging library like Serilog. In that case, batches of events can be sent in JSON format directly to Seq's HTTP API.

Events are POSTed to the /api/events/raw endpoint:

POST https://localhost:5341/api/events/raw

The body of the request contains one or more events in the format below:

{
  "Events": [{
    "Timestamp": "2015-05-09T22:09:08.12345+10:00",
    "Level": "Warning",
    "MessageTemplate": "Disk space is low on {Drive}",
    "Properties": {
      "Drive": "C:",
      "MachineName": "nblumhardt-rmbp"
    }
  }]
}

The Properties element can be omitted if an event does not carry any properties.

An Exception field can be specified at the top level (beside Properties, not under it) if required.

If an API key is required, it can be specified as ?apiKey= in the URL, or sent in the X-Seq-ApiKey HTTP header.
