Referly Atlas sends your store’s events to Reddit from its servers, through Reddit’s Conversions API. Page views, product views, carts and purchases reach your Reddit Pixel without depending on the visitor’s browser, with customer details hashed before they leave. This guide walks you through finding the two values Reddit asks for, adding the pixel in Atlas, and checking that events arrive.

​
Before you start

You need:
  • A store in Atlas that is set up and live. Only stores that are Running or Awaiting data send events. See Store statuses.
  • A Reddit Pixel in Events Manager. Atlas sends to a pixel you already have, it does not create one.
  • Access to the Conversions API settings of your Reddit Ads account, so you can generate an access token. The token is account level and Reddit shows it once.
If this is your first pixel, read Pixels and destinations first: it explains what a pixel is in Atlas and what every pixel row shows.

​
Step 1: Find your Pixel ID

1

Open Events Manager

In Reddit Ads Manager, open Events Manager.
2

Copy the Pixel ID

Copy the Pixel ID shown at the top. It looks like a2_abc123def456.
Reddit’s own article: Install the Reddit Pixel on your website. The same steps sit in the Where to find it tooltip beside the field in Atlas, and the How to find it link under the field opens Reddit’s article.

​
Step 2: Create an access token

1

Open the Conversions API setup

In Events Manager, open Conversions API, then Set up manually.
2

Generate the token

Select Generate Access Token and copy it. The token is account level and shown once, so paste it into Atlas right away.

​
Step 3: Add the pixel in Atlas

1

Open Pixels and destinations

In the left sidebar of Atlas, open Pixels and destinations for the store, then select + Add pixel.
2

Choose Reddit

In the Add your tracking pixel dialog, select the Reddit chip. Leave Method on Add a new pixel. If another store of your business already sends to this pixel, choose Use an existing pixel instead and Atlas copies its ids and keys to this store. See Use an existing pixel.
3

Paste the two values

Fill in Pixel ID and Access token. Name (optional) helps you tell pixels apart when a store sends to more than one Reddit Pixel.
4

Choose the events to send

Under Events sent, keep or change the events Atlas pre-selected for your business type, limited to the events Reddit accepts (see the table below). See Default events by business type.
5

Save

Select Add pixel. Atlas shows the Pixel saved screen with a Data flowing badge.
Add pixel dialog with Reddit selected, showing the Pixel ID and Access token fields On the Pixel saved screen, use You can verify that here to send a test event straight away. Atlas answers Test event accepted with the HTTP status Reddit returned, or shows Reddit’s own error message so you can correct the ID or token.

​
Events Atlas sends to Reddit

Reddit has no standard trial or subscription event, so Atlas sends Start trial and Subscribe as custom events named StartTrial and Subscribe. Initiate checkout and Add payment info are not sent to Reddit. Only the events ticked under Events sent are forwarded. Orders and conversions are always evaluated; the browser events (page views, product views, carts, searches) are forwarded only when a pixel wants them.

​
Verify that events arrive

  1. Send a test event. On the pixel row, open the row’s menu and choose Send test event. A toast confirms that Reddit accepted the event, or shows Reddit’s error. Test events time out after 10 seconds.
  2. Read the delivery line. The line under the pixel reads how many events reached Reddit in the last 24 hours, for example 8 sent in 24 h, or 8 sent, 2 failed in 24 h when some were rejected. A green dot means Live: events are being sent. See Pixel states.
  3. Watch Live activity. Open Live activity in the left sidebar and filter by destination to see each event’s status and Reddit’s response. See Live activity.

​
Troubleshooting

Atlas shows Reddit’s error next to the test. Check the Pixel ID first, then the token: Atlas never shows a saved token again, so select Edit on the row and paste a fresh one (a blank field keeps the saved value). Test events time out after 10 seconds, so a slow answer also counts as a failure: try once more.
Atlas sends only from stores that are Running or Awaiting data, only the events ticked under Events sent, and never test-mode orders. Check that the platform switch at the top of the Reddit row is on, then open Live activity and read the Status column: Skipped means no consent or no identifiers Reddit can match, Filtered means an event filter stopped it, Deduped means the same event was already sent within 48 hours. See Delivery statuses.
That is expected. Reddit has no standard event for a trial or a subscription, so Atlas sends them as custom events named StartTrial and Subscribe. Look for those custom event names in Reddit when you build reports or optimise campaigns on them.
