Connect LY Ads (Display)
Connect your LY Ads (LINE Yahoo, Japan) Display Ads account using your Yahoo! JAPAN Business ID. The AI handles performance reporting and management for campaigns, ad groups, and creatives.
What you'll need
A Yahoo! JAPAN Business ID with access to your LY Ads Display Ads account
How to connect
On your workspace's Data sources page, click Connect on the LY Ads (Display) card.
Click Sign in with Business ID and approve access in the pop-up. If you've already connected Search Ads, you can click Continue with existing authorization to skip signing in.
Choose the ad account you want to connect from the list and click Connect. You can't connect an MCC (a parent account that manages multiple ad accounts). Click it to expand the ad accounts underneath, then choose one of those.

Example requests
"Summarize impressions and click-through rate by creative for this month's display ads."
"Cut the budget for underperforming ad groups."
Troubleshooting
It says no ad accounts are available
The Business ID you approved doesn't have access to a Display Ads account. An ID with Search Ads access only won't show Display accounts.
The sign-in window doesn't open
Your browser blocked the pop-up. Use the pop-up blocker icon in the address bar to allow pop-ups for this site, then try again.
It says the authentication window was closed or timed out
You closed the window before finishing, or signing in took too long. The connection just wasn't saved and nothing else is affected, so start over.
