# Delta Exporting

Gormic supports **delta-based data exporting** to allow clients to efficiently sync only the data that has changed since a specific point in time.

### How Delta Export Works

Delta exporting uses three key fields to control and continue syncing:

| Field          | Description                                                                                                              |
| -------------- | ------------------------------------------------------------------------------------------------------------------------ |
| `updatedSince` | The ISO timestamp to fetch records **modified after**. Use this to start your export.                                    |
| `offset`       | A **cursor value** returned from the previous response, used to continue pagination **within the same `updatedSince`** . |

Continue until `next` is no longer included in the response, indicating that there are no more records to fetch.

> Export APIs for resources like **orders**, **products**, **reservations**, and more are documented individually in the **API Reference**.
