The easiest way to send your first event data to Axiom is with a direct HTTP request using a tool like cURL. 
curl -X 'POST' 'https://AXIOM_DOMAIN/v1/datasets/DATASET_NAME/ingest' \
    -H 'Authorization: Bearer API_TOKEN' \
    -H 'Content-Type: application/x-ndjson' \
    -d '{ "http": { "request": { "method": "GET", "duration_ms": 231 }, "response": { "body": { "size": 3012 } } }, "url": { "path": "/download" } }'
Replace AXIOM_DOMAIN with api.axiom.co if your organization uses the US region, and with api.eu.axiom.co if your organization uses the EU region. For more information, see Regions.Replace API_TOKEN with the Axiom API token you have generated. For added security, store the API token in an environment variable.Replace DATASET_NAME with the name of the Axiom dataset where you send your data.
To send events continuously, Axiom supports a wide range of standard tools, libraries, and platform integrations.
