Connecting Craft CMS to Reddit
Craft is a developer-oriented CMS, usually built bespoke by an agency, which means the implementation is whatever that agency decided and nothing is standard. Reddit's audience blocks trackers at rates well above the web average, which makes its browser pixel the least reliable in this list and its server-side path the most necessary. The join between them succeeds or fails on one thing: whether the rdt_cid click identifier reaches the Craft Commerce order before the conversion happens, because Reddit can only match a conversion it can tie back to a click it recognizes.

Craft CMS to Reddit CAPI: keep rdt_cid alive through static caching
Craft's static caching hides rdt_cid from PHP, so capture it with a script posting to an uncached endpoint that writes it to the Commerce cart. On completion, send Purchase from the PHP listener to Reddit's Conversions API with rdt_cid, hashed order email, order total and currency, and the order reference as conversion ID.
On a Craft site the rdt_cid usually dies on the landing page, before any order exists. Full-page static caching, often done with Blitz or a CDN, serves stored HTML, so PHP never sees the query string. Check how your cache treats query strings, then capture rdt_cid with a small script that posts it to an uncached endpoint, which writes it to a custom field on the Commerce cart. Don't lean on the Reddit Pixel cookie for this; a large share of these visitors block it.
When the order completes, send a Purchase from the PHP listener to the Reddit Conversions API with the stored rdt_cid, the hashed order email, the order total in the order's currency, and the order reference as the conversion ID. Given how little Reddit traffic runs the pixel, server-only is a reasonable choice for a Craft store, and it also removes the risk of a confirmation template double-firing.
Reddit spend tends to drive first visits rather than same-session sales, so expect some Craft orders from Reddit clicks to arrive days later. Store the click timestamp next to rdt_cid and check Reddit's current attribution window in Ads Manager before deciding which late orders to send. Check whether Reddit accepts refund adjustments; if not, net refunds out in your own reconciliation.
Craft → Reddit · what breaks
Why this join usually fails — Craft → Reddit
- 01
The rdt_cid click identifier never reaches Craft
Craft's template caching and static caching plugins both serve stored output, and because every build is custom, where the capture code lives differs per site. There is no standard place to look.
- 02
Every install is bespoke
There is no standard Craft setup, so an approach that worked on another Craft site may have nothing to attach to on this one. Read the build before quoting.
- 03
An audience that blocks trackers by habit
Coverage on Reddit traffic is structurally lower than on other networks. That is a property of who uses Reddit, not a broken implementation, and chasing a benchmark this audience will not give you wastes time.
- 04
Nothing reconciles afterwards
Reddit Ads Manager reports events received and matched. Expect lower match rates here than on Meta or Google and report the gap rather than explaining it away — reconcile against your own records for the same window.

How Craft and Reddit actually connect
- 1
Craft CMS holds the truth
Craft installs are bespoke by nature. Establish how this particular build models a completed order before assuming anything transfers from another Craft site.
- 2
Reddit needs a click to match
Reddit matches server events on the click identifier and hashed customer information. Reddit's Conversions API is younger than Meta's and its documentation moves, so confirm the current endpoint and required fields directly rather than from an integration blog post.
- 3
The identifier is the bridge
The rdt_cid click identifier, captured at the visit and carried into the Craft Commerce order.
- 4
The event source decides reliability
Fire from the event listener in PHP rather than a Twig template, which may be cached.
- 5
Deduplication at the destination
Reddit deduplicates on a conversion identifier carried by both the pixel and the server event. Because so much Reddit traffic never runs the pixel, sending server-side only is a legitimate choice here in a way it rarely is elsewhere — and it removes the deduplication problem entirely. Decide deliberately rather than running both and hoping.

Deduplicated correctly

Craft → Reddit · when not to buy
When you don't need this — Craft → Reddit
- If Reddit already reports conversions that reconcile against Craft CMS's records within a few percent, this join is working and there is nothing to buy.
- Measure identifier coverage yourself first — pull your last hundred orders and count how many carry the rdt_cid click identifier.
- If the original agency is still engaged, the fastest path is usually specifying the field and having them add the hook.
- If your Reddit strategy is organic community presence rather than ads, none of this applies — that traffic has no click identifier by definition.

FAQ
Craft → Reddit questions, answered
It can stop server-side code from ever reading rdt_cid on the landing page. Capture it client-side and write it to the cart through an uncached request, or confirm how your cache handles query strings.
Only with the order reference as a shared conversion ID on both. Many Craft stores send server-only to Reddit because the pixel misses so much of that audience anyway.
Almost always because the rdt_cid click identifier never reached the Craft Commerce order. Craft's template caching and static caching plugins both serve stored output, and because every build is custom, where the capture code lives differs per site. There is no standard place to look. Measure coverage before debugging the dispatch.
The rdt_cid parameter on your landing page URL. The Reddit Pixel also keeps its own identifier in a cookie, but on this audience specifically the cookie frequently does not exist — ad-blocker and tracker-blocker use on Reddit traffic runs well above average. The URL parameter is what survives; persist it server-side the moment you see it.
The Craft Commerce order-complete event. Fire from the event listener in PHP rather than a Twig template, which may be cached.
Reddit Ads Manager reports events received and matched. Expect lower match rates here than on Meta or Google and report the gap rather than explaining it away — reconcile against your own records for the same window.
