# Create a contact

`POST /contacts`

Creates a contact in the workspace.

Tags are linked by `id` or `name` and must already exist in the workspace — unknown tags are ignored. Use `PATCH /contacts/{contactId}/tags` to create tags on demand.

`customProperties` are keyed by property name and only properties already defined in the workspace are persisted.
