Improved JSON ingestion flexibility

The ingest endpoint just got smarter. We’ve expanded support for the Content-Type: application/json header, so it now accepts both JSON arrays and newline-delimited JSON (NDJSON).

This improvement solves a common pain point for teams working with third-party tools or SDKs that don’t allow customizing the Content-Type header. Previously, sending NDJSON required setting application/x-ndjson, which wasn’t always feasible. Now, Axiom accepts NDJSON even when the header is set to application/json, making integrations simpler and more forgiving.

Whether you’re piping logs from a custom client or wiring up a webhook, your data gets where it needs to go, no header gymnastics required.

Try it out today or read more in the documentation.
