### Syncing segments

Sync data from any source to PAR Retail Open Commerce segments

#### Record matching

To match rows from your model to segments in PAR Retail Open Commerce, you need to select the model column that contains values that match the **Membership UUID** field.
Refer to the [record matching docs](https://docs.hightouch.com/syncs/record-matching.md) for more information.

#### Field mapping

Hightouch lets you sync segment fields via [field mapping](https://docs.hightouch.com/syncs/mapping-data.md).
You can map data from any of your model columns to the default segment fields.
Ensure your model's columns have the same data types as the fields you want to sync to.

#### Split retries

PAR Retail Open Commerce counts all segments in a batch as rejected if the request contains a single invalid segment. To pinpoint which segments are getting rejected with which errors and reduce the number of valid segments that get retried, you can enable [split retries](https://docs.hightouch.com/syncs/retries.md#split-retries).

### Syncing events

See the [events syncs](https://docs.hightouch.com/syncs/types-and-modes.md#event-syncs) documentation for more information.

#### Record matching
