# Contact

Create, read, update and search contacts and their custom properties.

Contacts are the people your business talks to. Each contact has standard fields (name, phone number, email, and so on) plus **custom properties** that you define as columns on your contact board.

### Custom properties

1. Call `GET /api/crm/contact/filter-fields` or `GET /api/crm/contact/{id}/property` to see the available properties and their column IDs and types.
2. Read a contact's values from `crm_column` in `GET /api/crm/contact/{contact_id}`. Values are keyed by property name.
3. Write values with `PUT /api/crm/contact/{id}/property`, or with `values` when creating a contact.
4. Create new properties with `POST /api/crm/contact/property`.
