Internal Error on Creating Contactlist

[ghilman]

Hi,

After moving to access token from API key, i am getting 500 internal error while creating a contactlist. It was working properly when i created it using API key but now it is throwing 500 internal error.

Thanks

Hey, @ghilman 👋 Can you verify specifically which endpoint you are trying to access? Is it this one — Create a new contact list

Thank you! — Jaycee
