+The data plane resolves `credential_ref` to `DD_CRED_<SLUG>_API_KEY`, read from its local environment, where `<SLUG>` is the reference upper-cased with every character that is not an ASCII letter or digit folded to `_` (so `acme_dd` becomes `ACME_DD`). To keep that mapping unambiguous — so two different references cannot silently fold onto the same variable — use only lowercase letters, digits, and underscores in `credential_ref`; the control plane and dashboard enforce `^[a-z0-9_]+$`.

 Observability exporters are dynamic resources configured through `/admin/v1/observability_exporters`.
 
-Current exporter support is `otlp_http` only.
+Four kinds are supported — `otlp_http` (request traces), `object_store` (batched NDJSON to S3 / GCS / Azure Blob), `aliyun_sls` (Alibaba Cloud SLS logstore), and `datadog` (Datadog Logs intake). See [Observability Exporters](../configuration/observability-exporters.md) for each kind's fields, credential resolution, and destination validation.
