## Syncing

Hightouch supports syncing the following Reply.io objects:

* `People`

### Sync modes

* **Upsert**: pushes new objects to Reply.io *and* updates fields that change in your warehouse.
* **Update**: only updates particular fields on existing objects in Reply.io. It does *not* add new objects.

### Record matching

Records can be matched from your source to your Reply.io workspace by the **contact's email** only.

## Other considerations

As per their [documentation](https://apidocs.reply.io/#32e27eaa-b6b1-496e-8504-04b676aec3c1),
Reply.io's API is limited to *15,000 requests per user per month*.
This is important to keep in mind when syncing large amounts of data since **Upsert** mode
will make one API call per record synced and **Update** mode will make up to two API calls per record synced
(one to check that user exists and the other to update the user). Please plan your syncs accordingly.

[If you'd like to increase this rate limit, please contact Reply.io support.](https://support.reply.io/en/articles/978063-api-rate-limits).

## Tips and troubleshooting

To see the exact API requests and responses from each sync run, use the [live debugger](https://docs.hightouch.com/syncs/debugger.md). To get notified by Slack, PagerDuty, SMS, or email when a sync fails, set up [sync alerts](https://docs.hightouch.com/syncs/alerting.md). If you run into an issue this page doesn't cover, [contact support](#pylon-chat).
