Hi, I’ve been trying to publish another ad campaign on tiktok with spark ads, and ive had no problems in the past doing this and i have posted many different campaigns before, but now im trying to do it again and it keeps coming up with the message ‘spark aco param error’ does anyone know what this means and as to how i can resolve this issue?
the “aco param error” in tiktok spark ads happens due to issues with ad settings or permissions. check if your account is linked to the business center and ensure the ad authorization code is correct.
also, verify the video id and campaign settings.
if it still fails, contact tiktok support for help.
