REST API polling and logging

Poll a REST API endpoint, loop through results, and log data to New Relic.

Important

Selectors are optional for full payloads. Most workflow tools support direct response object references.

Simple GET and log

Basic API polling and full response logging:

What this workflow does:

Trigger via schedule (e.g., every 5 minutes) or manual run
HTTP Request Step:
- Method: GET
- URL: https://pokeapi.co/api/v2/pokemon
- Save response body to variable (e.g., {{.http_response}})
Log/Create Event Step:
- Send entire {{.http_response.body}} as payload
- No selectors needed—pass through raw JSON

REST API with loops and selectors

Fetch all results from REST API, loop through items, make individual calls, and log extracted data.

Requirements: API access and log ingest permissions.

What this workflow does:

Fetch all results from REST API endpoint
Loop through each response result
Make individual API calls per item using loop data
Extract specific fields using selectors
Log extracted data to New Relic with custom attributes

Key actions: http.get, newrelic.ingest.sendLogs

REST API to CSV conversion

Fetch API data, convert JSON to CSV, log to New Relic, and share via Slack.

Requirements: API access and Slack token in secrets.

What this workflow does:

Fetch time data from World Time API by timezone
Convert JSON response to CSV
Log CSV to New Relic
Post CSV to Slack channel

Key actions: http.get, utils.transform.toCSV, newrelic.ingest.sendLogs, slack.chat.postMessage

name: jsontocsv

    timezone:
      type: String
      defaultValue: 'America/Los_Angeles'
