Create a contact

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 <u>list filtering</u> to check if a record exists before creating.
