I'm trying to use Transporter to lookupMetadata for my app ID 1363309257, using an API key instead of a username and password.
I created my API key on the https://appstoreconnect.apple.com/access/api page, and configured it with the App Manager role.
I'm using my API key like this:
"/usr/local/itms/bin/iTMSTransporter -m lookupMetadata -apiIssuer 69a6de6f-0d6d-47e3-e053-5b8c7c11a4d1 -apiKey 3S3G8T48YW -app_platform ios -apple_id 1363309257 -destination /tmp"
The apiKey secret file is stored in ~/.appstoreconnect/private_keys/AuthKey_3S3G8T48YW.p8
When I run that command, I get this error:
iTMSTransporter says: "You cannot access '1363309257'. An Admin or App Manager has limited your access to this item, or the item does not exist. (1198)"
I know my API key is good/correct and the App Manager role is correctly configured, because I can use that same secret key to generate a JWT and use it successfully with the REST API. When I curl https://api.appstoreconnect.apple.com/v1/apps/1363309257 using my JWT, I see my app in the response.
Using the iTMSTransporter with the "-jwt" option with that same JWT fails, with exactly the same "You cannot access" error message.
Is this my fault? Are API keys just broken with iTMSTransporter? Do I need to report a bug?
What if anything did you do to resolve this? I'm having the same issue after upgrading my system. I've never changed any persmissions or access in app store connect and it had been working before.
