When using the New Relic REST API, you need to replace some ID placeholders (like $APP_ID
, $KEYTX_ID
, $PLUGIN_ID
, $COMPONENT_ID
, etc.) with the ID for an app, transaction, or other component.
You can use New Relic One to get some of these IDs. You can also get a list of IDs using the REST API Explorer.
