# Upload data

Use `client.Reconciliation.Upload` to upload external statement data.
```go client.Reconciliation.Upload theme={"system"}
file, err := os.Open("statement.csv")
if err != nil {
// handle error
}
defer file.Close()
uploadResp, resp, err := client.Reconciliation.Upload("stripe", file, file.Name())
```
| Field | Type | Description |
| :--------- | :---------- | :------------------------------------------------------------------ |
| `source` | `string` | Label describing where the data came from, for example `stripe`. |
| `file` | `io.Reader` | Open file or other readable source containing the external records. |
| `fileName` | `string` | Filename sent to Core, typically `file.Name()`. |
Use `uploadResp.UploadID` as the `UploadID` when you [start reconciliation](/sdks/go/reconciliation/start-reconciliation).
```json 201 Created wrap theme={"system"}
{
"upload_id": "upload_8c700d1b-09c0-4ef4-9ab1-a0decf3d0aa3",
"record_count": 1000,
"source": "Stripe"
}
```
| Field | Type | Description |
| :------------- | :------- | :---------------------------------------------------------------------- |
| `upload_id` | `string` | Unique ID for the upload. Store it to start a batch reconciliation run. |
| `record_count` | `number` | Number of records found in the file. |
| `source` | `string` | Label you passed for the data origin. |
