`GET /v1/batches/{id}`

Send your API key as a bearer token: `Authorization: Bearer ssms_sk_...`. Test keys run this endpoint against the [sandbox](/docs/sandbox); see [Authentication](/docs/authentication) for key modes and scopes.

Every error has the same JSON shape, and `request_id` matches the `X-Request-Id` response header. [Errors](/docs/errors) lists every code and what to do about it.

```json
{
  "error": {
    "code": "invalid_request",
    "message": "What went wrong, in plain words.",
    "param": "the_field",
    "request_id": "req_a1B2c3D4e5F6g7H8"
  }
}
```

## Examples

### curl

```bash
curl -X GET "https://api.joinsimplesms.com/v1/batches/bc_a1B2c3D4e5F6" \
  -H "Authorization: Bearer $SIMPLESMS_API_KEY"
```

### Node.js

The Node.js SDK does not wrap this endpoint yet; call it with `fetch`.

```javascript
const res = await fetch('https://api.joinsimplesms.com/v1/batches/bc_a1B2c3D4e5F6', {
  method: 'GET',
  headers: {
    Authorization: `Bearer ${process.env.SIMPLESMS_API_KEY}`,
  },
});

if (!res.ok) throw new Error((await res.json()).error.message);
const data = await res.json();
```

### Python

The Python SDK does not wrap this endpoint yet; call it over HTTP.

```python
import json, os, urllib.request

req = urllib.request.Request(
    "https://api.joinsimplesms.com/v1/batches/bc_a1B2c3D4e5F6",
    method="GET",
    headers={
        "Authorization": f"Bearer {os.environ['SIMPLESMS_API_KEY']}",
    },
)
with urllib.request.urlopen(req) as res:
    data = json.load(res)
```
