Endpoint Details

Headerprivate_key<Send-Your-Data API key>
  • We recommend sending logs in batches to minimize network calls.
  • Group logs from the same application, subsystem, and computer under a single API call using the “logEntries” property.
  • The API is limited to a message size of 2MB which is approximately 3,000 medium-sized logs.
  • If you are using Ajax or a similar technology, you may need to send the data with JSON.stringify()).

  • If you are sending a JSON payload note, we suggest escaping it and then inserting it into the text field, which should be sent as a string.
  • If sent in timestamp, use milliseconds or microseconds. If not sent in timestamp , we will inject the UTC time at the time the request is received.
