Reddit Ads
This page describes how to use Activations with Reddit Ads.
Reddit Ads is an advertising platform that allows businesses to engage with Reddit's diverse and active community. Activations can sync your customer data to Reddit Ads, helping you create targeted campaigns to reach specific subreddits, demographics, and interests.
Getting Started
Navigate to the Destinations page in Activations and click New Destination.
Select Reddit Ads from the menu.
Enter your Reddit Ad Account ID if you have one. This should match what you see under Assets > Ad Accounts in your Reddit account. Make sure to include the prefix (e.g.,
t2_abc123). If an ID is not provided, Activations will default to the parent account's ID.
Click Connect and proceed through the OAuth flow to connect your Reddit Ads account to Activations.

Custom Audiences
Sync Keys
Reddit will only accept hashed values for Custom Audience sync keys. Activations will hash before sending to Reddit if you provide unhashed values. If you provide pre-hashed values, they must follow this format:
- The email address should be lowercase
- The local part of the email address should have any dots removed, and any text after a plus sign should be removed
- SHA-256 should be used to hash the identifier, and 64 lowercase hex digits should be given
Creating a Sync
Select Custom Audience Users as the destination.
Select your Sync Key.
Select an audience. You can select from existing audiences in the dropdown or create a new one. You cannot create an audience with the same name as an existing one.
