# Custom Fields List

> List every custom field defined on your ChatSyncs account via the API, including each field's reply type. Use when a developer asks how to discover valid custom field names before calling Assign Custom Fields.

Lists every custom field defined on your account, with its `reply_type` (Text, Number, Date,
Email, Phone — see
[Subscriber Manager's Custom Fields](/learn/whatsapp-subscriber-manager#custom-fields)).
