# Pagination & syncing

> Page through large result sets and sync only records that changed since the last run.

## Pagination

To fetch the next page, set the `cursor` parameter to the `pagination.cursor` value returned in the last response.

**Example request:**

<CodeGroup>
  ```http Request theme={null}
  GET https://api.paytsoftware.com/v1/invoices?administration_id=81&cursor=2897875
  Authorization: Bearer IBzLDErQvt9gOmSLarUtDy06emduHZmKEG2OSPdHpJ8
  ```

  ```bash cURL theme={null}
  curl 'https://api.paytsoftware.com/v1/invoices?administration_id=81&cursor=2897875' \
  --header 'Authorization: Bearer IBzLDErQvt9gOmSLarUtDy06emduHZmKEG2OSPdHpJ8'
  ```
</CodeGroup>

**Response:**

```json theme={null}

    }
}
```

## Syncing data

The `updated_after` parameter requests only records that have changed since a given timestamp (for instance, the last time data was synced). When the last page of data is processed, store the `updated_at` timestamp of the most recently updated record in the last response and use it to fetch all updated records in a future run.

<Tip>
  When a response contains no records, reuse the previous `updated_at` timestamp for the next sync session: do not advance it, or you may skip records.
