+description: The pipeline field in Wrangler pipeline binding configuration has been renamed to stream. The old field is deprecated but still accepted.

+
+The `pipeline` field inside the `pipelines` binding configuration in your [Wrangler configuration file](/workers/wrangler/configuration/) has been renamed to `stream`. The old field is deprecated but still accepted.
+
+Update your configuration to use `stream` to avoid the deprecation warning.
+
+**Before (deprecated):**
+
+<WranglerConfig>
+
+```jsonc
+{
+	"pipelines": [
+		{
+			"binding": "MY_PIPELINE",
+			"pipeline": "<STREAM_ID>"
+		}
+	]
+}
+```
+
+</WranglerConfig>
+
+**After:**
+
+<WranglerConfig>
+
+```jsonc
+{
+	"pipelines": [
+		{
+			"binding": "MY_PIPELINE",
+			"stream": "<STREAM_ID>"
+		}
+	]
+}
+```
+
+</WranglerConfig>
+
+No other changes are required. The binding name, TypeScript types, and runtime API (`env.MY_PIPELINE.send(...)`) remain the same.
+
