# Reconciliation Configuration

> Configure reconciliation strategy, progress updates, and retries in Blnk.

This page covers the settings that control how Blnk runs reconciliation jobs and reports progress.

***

## Reconciliation settings

Use these settings to configure the default reconciliation strategy, progress updates, and retry behavior.

<CodeGroup>
  ```bash blnk.env theme={"system"}
  BLNK_RECONCILIATION_DEFAULT_STRATEGY=one_to_one
  BLNK_RECONCILIATION_PROGRESS_INTERVAL=100
  BLNK_RECONCILIATION_MAX_RETRIES=3
  BLNK_RECONCILIATION_RETRY_DELAY=5s
  ```

  ```json blnk.json theme={"system"}
  {
    "reconciliation": {
      "default_strategy": "one_to_one",
      "progress_interval": 100,
      "max_retries": 3,
      "retry_delay": "5s"
    }
  }
  ```
</CodeGroup>

|                                         | Description                                                         | Default      |
| :-------------------------------------- | :------------------------------------------------------------------ | :----------- |
| `BLNK_RECONCILIATION_DEFAULT_STRATEGY`  | Default matching strategy used for reconciliation.                  | `one_to_one` |
| `BLNK_RECONCILIATION_PROGRESS_INTERVAL` | Number of records Blnk processes before it emits a progress update. | `100`        |
| `BLNK_RECONCILIATION_MAX_RETRIES`       | Maximum number of retry attempts for failed reconciliation work.    | `3`          |
| `BLNK_RECONCILIATION_RETRY_DELAY`       | Time Blnk waits before retrying failed reconciliation work.         | `5s`         |

### `BLNK_RECONCILIATION_DEFAULT_STRATEGY`

This sets the reconciliation strategy Blnk uses by default.

Use `one_to_one` when one ledger record should match one external record. Change it only when your reconciliation flow regularly needs one-to-many or many-to-one matching.

### `BLNK_RECONCILIATION_PROGRESS_INTERVAL`

This controls how often Blnk reports progress while a reconciliation job is running.

<Tip>
  **Tip:** Use a smaller value when you want more frequent progress updates. Use a larger value when you want fewer progress events during large jobs.
