What is a Reddit Conversions API token?A Conversions API access token is a non-expiring secure key that allows Upstack Data to send conversion event data to Reddit’s Conversions API. The token can be used by any administrator for any ad account within your business. Reddit recommends using this token over OAuth for Conversions API access.

Steps to generate your Reddit CAPI token

1

Sign in to Reddit Ads Manager

Sign in to Reddit Ads Manager at ads.reddit.com or business.reddit.com.
2

Open Events Manager

Click the menu (top-left corner) and select Ads → Events Manager.
3

Open the Conversions API settings

In the left-hand menu of the Events Manager, click the Conversions API tab.This opens the Conversions API settings page where access tokens are managed.
4

Generate the access token

In the Conversions access token section, click the + Generate Access Token button.A pop-up window will appear prompting you to name the token.
5

Name your token

Enter an easily identifiable name for the token (e.g., Upstack Data or Upstack CAPI).
A descriptive name makes it easier to identify which integration the token belongs to if you generate multiple tokens for different platforms or environments.
Click Generate to create the token.
6

Copy your CAPI token

Reddit will display the access token — a string of letters and numbers.
Copy the token immediately to a secure location. Reddit may not show the full token again after you close the dialog. If lost, you’ll need to generate a new one.
The token is a non-expiring secure key, so it does not need to be refreshed periodically. However, you should rotate it if you suspect it has been compromised.
7

Add the token to Upstack Data

Sign in to Upstack Data at app.upstackdata.com and open your Reddit destination under Event Destinations. Paste the token into the Conversions API access token field.
The Conversions API token is sensitive — store it securely. Treat it like a password and never expose it in client-side code or share it publicly.
8

Verify the destination is healthy

In the Upstack dashboard, the Reddit destination card should show Healthy with a green status indicator within 5 minutes.If the status shows Unhealthy:
  • Confirm the token was pasted in full (no truncation, no whitespace).
  • Confirm the token was generated for the same Reddit Ads account as the Pixel ID.
  • Confirm the Pixel ID matches the pixel you generated the token for.
