Reddit Conversions API

Forward your AxiTrace server-side events to Reddit — the same way Facebook CAPI and TikTok Events API work. You paste two values from Reddit Ads Manager, and AxiTrace sends every tracked event to your Reddit Ads account in real time, server-side: immune to ad blockers and browser privacy features.

Prerequisites

• An active Reddit Ads account with a business (ads.reddit.com).
• Your AxiTrace workspace installed and tracking events (Web SDK, Shopify app, or a platform plugin).

1. Open Reddit Ads Manager → Events Manager.
2. Copy the Pixel ID shown at the top of the Events Overview page. It looks like a2_xxxxxxxxxxxx (older pixels may start with t2_ or p2_).

1. In Events Manager, open Conversions API in the left sidebar.
2. Click Generate Access Token, give it a name (e.g. "AxiTrace"), and click Generate.
3. Click Copy to Clipboard & Close immediately — the token is shown only once. If you lose it, generate a new one (up to 5 tokens per business).

The conversion access token is non-expiring and officially recommended by Reddit for CAPI — no OAuth app, no developer review, no token refresh needed.

1. In your AxiTrace workspace, go to Connections and open Reddit Conversions API.
2. Paste the Pixel ID and the Conversion Access Token.
3. Click Test Connection — AxiTrace sends a real test event to Reddit and shows the result immediately.
4. Pick the events to forward (all are enabled by default) and set the status to Active, then save.

Reddit provides an isolated test view at ads.reddit.com/events-manager/testing. Copy the Test ID shown there into the optional Test ID field in AxiTrace — all events will then land in the Event Testing tool instead of production reporting.

Event mapping

AxiTrace events map to Reddit's standard tracking types automatically:

With every event AxiTrace sends the available match keys: hashed email and phone (SHA-256), IP address, user agent, external ID, the Reddit click ID (rdt_cid) captured from ad clicks, the page URL, and — for revenue events — currency, value, item count and the product list.

Install the Reddit Pixel — init only

Add the Reddit Pixel snippet to your site without the rdt('track', 'PageVisit') line. The init call on its own writes the first-party _rdt_uuid cookie, which the AxiTrace SDK picks up and forwards with every server-side event as Reddit's user.uuid — the strongest match key Reddit offers (its equivalent of Meta's _fbp). Sites running CAPI without the pixel have no user.uuid at all.

<script>
!function(w,d){if(!w.rdt){var p=w.rdt=function(){p.sendEvent?p.sendEvent.apply(p,arguments):p.callQueue.push(arguments)};p.callQueue=[];var t=d.createElement("script");t.src="https://www.redditstatic.com/ads/pixel.js",t.async=!0;var s=d.getElementsByTagName("script")[0];s.parentNode.insertBefore(t,s)}}(window,document);
rdt('init','YOUR_REDDIT_PIXEL_ID');
// No rdt('track', 'PageVisit') — AxiTrace sends PAGE_VISIT server-side with a conversion ID.
</script>

Deduplication with the Reddit Pixel

Reddit deduplicates a browser event against a server event only when both carry the same conversion ID and the same event name; duplicates are processed hourly and the two copies must arrive within 2 days of each other. AxiTrace always sends a stable conversion ID on the server side.

If you deliberately want browser-side Reddit events (for example you already build audiences from them), then pass your own shared ID to both sides — rdt('track', 'PageVisit', { conversionId: '…' }) with the same value your server sends — or disable page.view for the Reddit connection in AxiTrace so only the pixel reports visits. Never run both unpaired.

Troubleshooting

Missed events (e.g. a Reddit outage window) can be re-sent by AxiTrace support using the replay tooling — failed sends are stored with full (redacted) request and response data for diagnosis.
