HTTP Get

This page provides a comprehensive reference for HTTP Get available in the workflow automation actions catalog. These actions enable you to perform HTTP GET request operations.

Prerequisites

For prerequisites, see HTTP actions.

Automatic request headers

All HTTP requests performed by Workflow Automation automatically include the following headers:

Header	Format
`X-Abuse-Info`	`Request sent by a New Relic WorkflowAutomation. {runId}` where `{runId}` is the workflow run ID
`User-Agent`	`NewRelic/WorkflowAutomation (region={region}; https://newrelic.com ; support@newrelic.com)` where `{region}` is the New Relic region

GET web data

Perform an HTTP GET call to retrieve data from an API endpoint.

Importante

If you need to pass sensitive data to an input, for example an Api-Key header, you can use values stored via the secretsManagementCreateSecret NerdGraph mutation.

Example

{
  "inputs": [
    {
      "key": "headers",
      "value": "{\"Api-Key\": \"${{ :secrets:NR_API_KEY }}\"}"
    }
  ]
}

Input	Type	Description
url	String	Required. The target URL for the request. The scheme must be included: `https://example.com`. See using workflow inputs for dynamic values.
urlParams	Map	Optional. The query parameters to append to the URL. Takes a stringified JSON object.
headers	Map	Optional. The headers to add to the request. Takes a stringified JSON object.
selectors	List	Optional. The selectors to get only the specified parameters as output.

Selectors

Purpose: Extract specific data from the API response.

Structure:

name: The variable name to store the extracted value
expression: JSONPath or expression to parse the response
Use responseBody | fromjson to parse JSON responses
Chain additional filters using dot notation (e.g., .abbreviation)

Output	Type	Description
responseBody	String	The body of the response.
statusCode	Int	The status code of the response.
success	Boolean	Status of the request.
errorMessage	String	Failure reason as message.
