Sign in to Application Management with a Yahoo! JAPAN ID, then register an app at app registration to issue a Client ID / application ID. Use that ID as appid in query parameters, or append it to the User-Agent header as Yahoo AppID: <Client ID> per the request guide.
Sign in to Application Management and create/manage an app in the dashboard. Yahoo! ID連携 uses Yahoo! ID連携 v2, which is OpenID Connect based; configure your app there and implement the flow described in Yahoo! ID連携 for APIs that require an access token.
Use the LY Ads API startup guide to apply for API use and add an application in the LY Ads API Management Console. This gives you a client_id, client_secret, and configured redirect_uri. Then have a Business ID user approve the app via the OAuth 2.0 authorization-code flow described in API Call and About OAuth2.0 to obtain an access token. Requests also need the base account ID in header x-z-base-account-id.
