# Product feed

| Feature                                               | Description                                                                                                                                                                                                                                                                                                                                     |

| **Automatic sync**                                    | Product feed is synced at least once a day. More frequently if needed.                                                                                                                                                                                                                                                                          |
| **Real-time delta sync and catalogue indexation**     | Delta-information/changes pushed to our API in near real-time, but it should always be complemented with a complete feed that Loop54 can synchronise with at least once a day. Loop54 can fetch changes or retailer can push changes.                                                                                                           |
| **Merge and sync different data sources and formats** | If different information needs to be synced, it does not have to be in the same feed as products. For example, Loop54 can enrich the feed with data from other sources, like images, CRM or sales data. Data can also be in different formats. Engine can index different formats from different sources and merge them. (e.g. CSV, XML, JSON). |
| **Real-time product removal**                         | Products that should be removed from the indext can be pushed through the API.                                                                                                                                                                                                                                                                  |
| **Partial deltas**                                    | Loop54 also allow for partial delta updates, that means you can send only the data that needs to be updated.                                                                                                                                                                                                                                    |
