## Pipeline binding configuration field renamed to stream

Jun 04, 2026 

[ Pipelines ](https://edgetunnel-b2h.pages.dev/pipelines/)[ Workers ](https://edgetunnel-b2h.pages.dev/workers/) 

The `pipeline` field inside the `pipelines` binding configuration in your [Wrangler configuration file](https://edgetunnel-b2h.pages.dev/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-2737)
* [  wrangler.toml ](#tab-panel-2738)

**JSONC**

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

**TOML**

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

**After:**

* [  wrangler.jsonc ](#tab-panel-2739)
* [  wrangler.toml ](#tab-panel-2740)

**JSONC**

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

**TOML**

```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.
