Create a contact

client.contact.create(, ?): ContactCreateResponse { id, createdAt, fields, 4 more }

POST/v1/contacts

Creates a new contact record.

After creation, Lightfield automatically enriches the contact in the background.

Supports idempotency via the Idempotency-Key header.

To avoid duplicates, we recommend a find-or-create pattern — use list filtering to check if a record exists before creating.
