I need help with getting apps
i got a new phone and I wanted to get my apps back, but it wouldn’t let me get them.

Do you use the same Apple ID on the new iPhone as on the old iPhone?
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.
See the following Apple articles
Sign in with your Apple ID -> Sign in with your Apple ID - Apple Support
Manage and use your Apple ID -> Manage and use your Apple ID – Apple Support (UK)
