# Create an address book entry (/api-reference/address-book/v1-address-book-post)

Adds a recipient to the account's address book, validating and standardizing the supplied address before saving it. This is the canonical path for the address book. The older `/v1/zapierActions/address-book` path is retained for existing integrations and behaves identically.
