New Relic's REST API lets you retrieve data from and push data to New Relic tools, as well as to configure features and perform delete operations. You can also use the API Explorer to understand the data available to you via the REST API, to obtain curl commands, and to see JSON responses.
Setup
The REST API command structure follows this template:
The GET command could also be a POST or DELETE, depending on the query intent.
To understand the placeholders, keep reading.
Tip
Our examples use curl as a common command line tool to pull metric timeslice data from the REST API. However, you can use any method to make your REST requests. The curl commands include target URLs, header information, and data which are relevant for any request mechanism.
URL
The API calls require a URL to specify the location from which the data will be accessed. You must replace the placeholder URL with the appropriate URL which will change depending on the type of data being requested. In general the URL follows this template:
https://api.newrelic.com/v2/applications/$APP_ID/metrics/data.jsonThe $APP_ID specifies the exact application or product for which the data is being requested. The information following this parameter will vary depending on the data request.
If you have an EU region account, the URL is:
api.eu.newrelic.com/v2/applications/$APP_ID/metrics/data.jsonTip
You can retrieve XML data instead of JSON by replacing .json with .xml.
API key $API_KEY
New Relic API requires a user API key: The user key is also used for our NerdGraph API.
In our REST API examples, we borrow the API key placeholder $API_KEY from Unix shell programming. Be sure to replace that and other user-specific variables when forming calls.
Query details (PAYLOAD)
The PAYLOAD contains the query details, which define:
- The metric name you want to query and the value you want to retrieve
- The defined time range for retrieving metrics
- (Optional): The average of the metric timeslice data by using summarize
Examples
See the following docs for example REST API use cases:
- APM examples (how to retrieve metric timeslice data from ).
- Browser examples (how to retrieve metric timeslice data from ). The REST API only returns the Lite browser agent script. For more information, see this table comparing Lite, Pro, and Pro+SPA types.
- Infrastructure alert examples
- Alerts examples (create alert conditions and configure notification channels, and more).
