I have two apple id's. How can I get them merged?

No, is not possible.

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.
