API Reference

Queues, Limits, and Errors

Concurrency is enforced per account across all API keys and endpoint formats

Automatic queueing

When every subscribed stream is active, the connection stays open until a slot is available. No client-side retry is needed while queued.

Queue headers

Successful responses include x-camel-queue-ms and x-camel-stream-limit.
