It lets your Laravel application publish jobs as a strict, language-agnostic JSON envelope — so Go, Python, Java, .NET and Node services consume them natively, without ever touching PHP `serialize()`. ## What you get - **Canonical wire envelope (`schema_version: 1`).** Every published message is a strict JSON document with a stable shape: `job`, `trace_id`, `data`, `meta` and `attempts`. - **A `trace_id` on every message.** A required correlation UUID is stamped on publish and flows across every service that touches the job — no manual plumbing. - **URN routing.** Jobs are identified by a URN (`urn:babel::`), not a PHP class name, so consumers in any language can route on a stable key. - **Drop-in broker drivers.** Choose your transport with one Laravel queue connection line — `babelqueue-redis`, `babelqueue-rabbitmq`, `babelqueue-sqs` or `babelqueue-artemis` (Apache ActiveMQ/Artemis over STOMP). Each extends the matching native driver, so standard jobs on the same connection pass straight through. - **Dead-letter queue (DLQ).** Unknown URNs and exhausted retries can be routed to a dead-letter destination instead of being silently dropped. ## The envelope ```json { "job": "urn:babel:orders:created", "trace_id": "7b3f9c2a-e41d-4f88-9b2a-1c0d5e6f7a8b", "data": { "order_id": 1042, "amount": 99.90 }, "meta": { "id": "f1e2d3c4-b5a6-4789-90ab-cdef01234567", "queue": "default", "lang": "php", "schema_version": 1, "created_at": 1749132727000 }, "attempts": 0 } ``` Continue to [Installation](/docs/laravel/1.x/installation/).
