SEC Filing financial Data

During Eikon Data API Beta there's no validity check for application ID. You can pass any non empty string to set_app_id method. This will change when the API is officially launched, but for now you can use any string as app ID. Your Eikon entitlements however are checked every time you start Eikon and every time you send a data request. This said I don't think the problem you're facing is related to the app ID. It sounds like you have other issues to resolve here such as installing Eikon and making sure you can successfully launch it. See my comment to your previous post on this thread.

In the screenshot you're launching the App ID Generator in a browser. Instead you need to launch it from Eikon application. Start Eikon application (not the browser version, but the full fat client installed locally on your PC), then type in the command/search bar "application ID generator" and pick the app from the autosuggest.

I just checked the entitlements on the account associated with the email address you use to sign into Eikon. As far as I can see your account is not subscribed to any products, which means you cannot start Eikon, you cannot retrieve any data from Eikon and you cannot use any Eikon APIs. If you believe this is in error and you should have an active subscription to Eikon, please contact your Thomson Reuters account manager or call TR Helpdesk.
