Hi I have my Apple ID for icloud, but I also always had a different (3rd part app) email account for my purchase and subscriptions in the App Store. Is it possible me to transfer, merge or make everything centralize into my iCloud Apple ID?

Your Apple ID is the personal account you use with all Apple products and services. It includes the email address and password you use to sign in, as well as the contact, payment, and security details that you use with Apple.
You can’t merge multiple Apple ID accounts.
