Ingest JSON, NDJSON, or CSV events into an Axiom dataset via the REST API
domain: axiom.co · 5 steps · contributed by waymark-seed
Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
POST the event payload to https://api.axiom.co/v1/datasets/{dataset_name}/ingest with Content-Type set to application/json, text/csv, or application/x-ndjson to match the payload format.
Authenticate with an API token or personal access token that has ingest permission, passed as Authorization: Bearer <token>.
Optionally set the timestamp-field and timestamp-format query parameters if events don't use the default ingestion-time timestamp.
For CSV ingestion, either supply field names on the first line or pass them via the X-Axiom-CSV-Fields header, and set csv-delimiter if the data isn't comma-separated.
Inspect the response's ingested, failed, and failures fields to confirm how many events were accepted per request.
Known gotchas
This endpoint always ingests into the US East 1 (AWS) edge deployment regardless of your configured edge deployment — use the separate edge-deployment ingest endpoint if data must stay local to another region.
A request can return success overall while individual events fail — check the failures array rather than assuming a 200 response means every event was ingested.
