Connecting Square Online to Reddit
Square Online orders settle into the same Square account as the card taken at the counter, which is a genuine advantage: the online and in-person halves of the business are already denominated in one ledger. 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 Square Online order before the conversion happens, because Reddit can only match a conversion it can tie back to a click it recognizes.

Specific to this pair
Square Online orders to Reddit CAPI with rdt_cid captured early
Capture rdt_cid on the first page Reddit traffic lands on and store it with any email given. Send online-channel Square orders to Reddit's Conversions API as Purchase, valued net of tax and tip in USD, with hashed email and phone, the Square order ID as conversion ID, and rdt_cid where matched. Check Reddit reaches your pickup radius.
A Square Online store on a Square-provided domain, with checkout on Square's pages, gives the Reddit pixel very little to work with, on an audience that blocks it anyway. rdt_cid has to be captured on the first page Reddit traffic lands on, ideally a page on your own domain or through whatever code injection your Square Online plan allows, and stored first-party together with the visitor's email if they give it.
Server-side, take orders from Square's webhooks, keep online-channel orders only, and send a Purchase to Reddit's Conversions API with value net of tax and tip in USD, hashed email and phone from the Square customer record, the Square order ID as the conversion ID, and rdt_cid where you could match it. Hashed contact data carries more of the load here than on most pairs, because on Square Online the click-ID join is often an email match rather than a field on the order.
Food and local-retail sellers should check whether Reddit can reach their delivery or pickup radius at all before building this. If most orders are pickup within a few miles, a geo-targeted Reddit campaign will produce small, noisy conversion counts; judge it on Square's order count for that location rather than on Reddit's reported value.
Square Online → Reddit · what breaks
Why this join usually fails — Square Online → Reddit
- 01
The rdt_cid click identifier never reaches Square Online
Square Online sites are frequently on a Square-provided domain, and checkout may hand off to Square-hosted payment pages depending on configuration.
- 02
Counter sales counted as online conversions
The convenience of one ledger is also the trap. If the sales channel is not filtered, every card swipe at the register lands in your ad reporting as a conversion you paid for.
- 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 Square Online and Reddit actually connect
- 1
Square Online holds the truth
The filter is the whole job. Square's default reporting cheerfully sums counter sales and online orders, and that total is not something any ad platform should be optimizing toward.
- 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 Square Online order.
- 4
The event source decides reliability
Send net of tips and taxes. Tips on food orders are substantial and are not your revenue.
- 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.

When you don't need this — Square Online → Reddit
- Measure identifier coverage yourself first — pull your last hundred orders and count how many carry the rdt_cid click identifier.
- If Square Online is a small side channel next to your counter business, measure it on order count and do not build an import for it.
- If your Reddit strategy is organic community presence rather than ads, none of this applies — that traffic has no click identifier by definition.

FAQ
Square Online → Reddit questions, answered
Check Square Online's tracking and custom-code options for your plan; we have not confirmed native Reddit pixel support. Sending server-side from Square order data works either way.
Filter Square orders by source and location so only Square Online orders are sent as Purchase events.
Almost always because the rdt_cid click identifier never reached the Square Online order. Square Online sites are frequently on a Square-provided domain, and checkout may hand off to Square-hosted payment pages depending on configuration. 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.
