# create_reddit_ads_audience Create an empty custom audience on a Reddit ad account, then fill it with update_reddit_ads_audience_users. Reddit only supports ONE kind of audience through the API — an uploaded CUSTOMER LIST matched on hashed emails and mobile advertising ids; pixel-retargeting, engagement and lookalike audiences are built by Reddit itself in Ads Manager and cannot be created here. The audience arrives empty and stays unusable until it matches roughly 1,000 redditors, and Reddit takes up to 4 hours to show a size change and up to 36 hours to finish processing a list — so do not create, upload and then report success on reach in the same breath.
