200 Status with API Explorer

Problem

You received an HTTP 200 status code, but the message body is empty.

Solution

To correct this, add an Accept header containing application/json or application/xml to your GET request. For example:

curl -X GET 'https://api.newrelic.com/v2/applications/YOUR_APP_ID/metrics/data.json'
     -H 'X-Api-Key:YOUR_API_KEY' -i
     -H 'Accept: application/json'

Cause

This may occur when using a default GET header that does not specify the accepted content type. For more information on HTTP headers, see this tutorial on Content negotiation using HTTP headers.
