+
+The [Reddit Pixel](https://business.reddithelp.com/s/article/reddit-pixel){:target="_blank"} lets advertisers send Segment events to the Reddit Pixel without any additional manual JavaScript installation. This destination has Segment events pre-mapped to Reddit Pixel events and metadata. You can edit this mapping and create new events - no custom code required.
+
+## Getting started
+
+1. From your workspace's [Destination catalog page](https://app.segment.com/goto-my-workspace/destinations/catalog){:target="_blank”}, find the Reddit Pixel destination and select **Add Destination**.
+2. Select the source that will connect to the Reddit Pixel destination.
+3. Open the destination settings and provide your Pixel ID. This can be found in the [Events Manager](https://ads.reddit.com/events-manager){:target="_blank"}.
+4. Configure and map the events you'd like to send to the Reddit Pixel. The destination pre-maps certain Segment events to Reddit Pixel events and metadata, but you can edit these values. You can also set up custom events.
+
+After enabling the destination, Segment will automatically initialize and load the Reddit Pixel on each page that Segment is tracking based on your mappings.

+The integration automatically pre-maps the Segment `messageId` to the Reddit conversion ID. If you wish to change this, you can pass a different unique conversion ID for every distinct event to its corresponding Reddit Pixel and CAPI event.

+
+To ensure your events are deduplicated:
+- Create a unique conversion ID for every distinct event. You can set this as a random number or ID. Similarly, you could set this to the order number when tracking purchase events.
+- Include the event in the Reddit Pixel and CAPI.
+- Ensure the conversion event name and conversion ID for its corresponding events match.
