# Run a command in an existing sandbox.

**POST** `/v1/sandboxes/{id}/exec`

Runs a command without replacing the sandbox, preserving its filesystem and state.

- **Operation ID:** `runSandboxCommand`
- **Success:** **200**
- **Authentication:** **Bearer key**

## Path parameters

| Name | Type | Requirement | Meaning |
| --- | --- | --- | --- |
| `id` | string | Required | Opaque, project-scoped Wildflower sandbox ID returned by create. The provider namespace is visible, but the random payload does not encode the provider-native ID. |

## Optional provider context

These headers are inline overrides. Connected project profiles keep the same fields outside individual requests.

| Name | Type | Requirement | Meaning |
| --- | --- | --- | --- |
| `X-Provider-Workspace` | string | Optional | Optional inline provider workspace override. Required with an inline Blaxel credential and omitted when using a connected profile. |

## Request and response

- **Request body:** [RunCommandInput](https://wildflower.computer/docs/reference/models/run-command-input/)
- **Response:** [CommandResult](https://wildflower.computer/docs/reference/models/command-result/)

## HTTP example

This credential-safe request and its representative success response are generated with the operation contract. Replace placeholder IDs and read secrets from your environment.

Request

```bash
curl --fail-with-body --request POST \
  "$WILDFLOWER_URL/v1/sandboxes/wf_e2b_AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA/exec" \
  -H "Authorization: Bearer $WILDFLOWER_API_KEY" \
  -H "Content-Type: application/json" \
  --data '{"command":"echo hello","cwd":"/workspace"}'
```

Response / 200

```json
{
  "sandboxId": "wf_e2b_AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA",
  "stdout": "hello\n",
  "stderr": "",
  "exitCode": 0
}
```

## SDK examples

Use the same operation through any generated client. Each snippet comes from the SDK generator rather than a hand-copied website example.

### TypeScript

```typescript
import { Wildflower } from "@wildflowercomputer/sdk";

const client = new Wildflower({
  wildflowerApiKey: process.env.WILDFLOWER_API_KEY,
});

const handle = client.sandboxes.attach("wf_e2b_AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA");
const result = await handle.runCommand({
  command: "echo hello",
  cwd: "/workspace",
});
console.log(result.stdout, result.stderr, result.exitCode);
```

### Python

```python
import os

from wildflower import (
    E2bCreateSandboxInput,
    ReadFileInput,
    RunCommandInput,
    WriteFileInput,
    Wildflower,
)

client = Wildflower(
    wildflower_api_key=os.environ.get("WILDFLOWER_API_KEY"),
)

handle = client.sandboxes.attach("wf_e2b_AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA")
result = handle.run_command(
    RunCommandInput(command="echo hello", cwd="/workspace")
)
print(result.stdout, result.stderr, result.exit_code)
```

### Rust

```rust
use wildflower::{
    CreateSandboxInput, FileEncoding, ListSandboxesOptions, ReadFileInput,
    RunCommandInput, WriteFileInput,
    Wildflower,
};

let client = Wildflower::new(std::env::var("WILDFLOWER_API_KEY")?)?;

let handle = client.sandboxes().attach("wf_e2b_AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA")?;
let result = handle.run_command(&RunCommandInput {
    command: "echo hello".to_owned(),
    cwd: Some("/workspace".to_owned()),
    env: None,
}).await?;
println!("{} {} {}", result.stdout, result.stderr, result.exit_code);
```

### Go

```go
client, err := wildflower.NewClient(os.Getenv("WILDFLOWER_API_KEY"))
if err != nil {
    return err
}

handle, err := client.Sandboxes.Attach("wf_e2b_AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA")
if err != nil {
    return err
}
cwd := "/workspace"
result, err := handle.RunCommand(ctx, wildflower.RunCommandInput{
    Command: "echo hello",
    Cwd: &cwd,
})
if err != nil {
    return err
}
fmt.Println(result.Stdout, result.Stderr, result.ExitCode)
```

### Zig

```zig
var client = try Wildflower.init(
    allocator,
    wildflower_api_key,
    transport,
);
defer client.deinit();

var handle = client.attach("wf_e2b_AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA");
var result = try handle.runCommand(.{
    .command = "echo hello",
    .cwd = "/workspace",
});
defer result.deinit();
std.debug.print("{s} {d}\n", .{ result.value.stdout, result.value.exit_code });
```
