## Pipeline binding configuration field renamed to stream

Jun 04, 2026 

[ Pipelines ](https://developers.cloudflare.com/pipelines/)[ Workers ](https://developers.cloudflare.com/workers/) 

The `pipeline` field inside the `pipelines` binding configuration in your [Wrangler configuration file](https://developers.cloudflare.com/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):**

* [  wrangler.jsonc ](#tab-panel-2575)
* [  wrangler.toml ](#tab-panel-2576)

JSONC

```
{  "$schema": "./node_modules/wrangler/config-schema.json",  "pipelines": [    {      "binding": "MY_PIPELINE",      "pipeline": "<STREAM_ID>"    }  ]}
```

TOML

```
[[pipelines]]binding = "MY_PIPELINE"pipeline = "<STREAM_ID>"
```

**After:**

* [  wrangler.jsonc ](#tab-panel-2577)
* [  wrangler.toml ](#tab-panel-2578)

JSONC

```
{  "$schema": "./node_modules/wrangler/config-schema.json",  "pipelines": [    {      "binding": "MY_PIPELINE",      "stream": "<STREAM_ID>"    }  ]}
```

TOML

```
[[pipelines]]binding = "MY_PIPELINE"stream = "<STREAM_ID>"
```

No other changes are required. The binding name, TypeScript types, and runtime API (`env.MY_PIPELINE.send(...)`) remain the same.

For more information on configuring pipeline bindings, refer to [Writing to streams](https://developers.cloudflare.com/pipelines/streams/writing-to-streams/#configure-pipeline-binding).
