## Provider API Context

<details>
  <summary>Show provider reference (optional)</summary>

  ```md theme={null}
  > Lists all available fields for contacts and companies.

  # List Fields

  Returns all available fields for contacts and companies, grouped by entity.
  Use this endpoint to discover field names before upserting contacts or companies.

  ## Field sources

  | Source       | Description                                                               |
  | ------------ | ------------------------------------------------------------------------- |
  | `default`    | Built-in fields available on every account (e.g. email, firstName, phone) |
  | `custom`     | Custom fields created by your team                                        |
  | `crm_synced` | Fields from your connected CRM's field mapping configuration              |

  ## CRM-synced fields

  When your team has a CRM connected, fields with `source: "crm_synced"` reflect the field mapping configured between lemlist and your CRM. These fields include an additional `crmField` property containing the corresponding field name on the CRM side.

  If no CRM is connected, no `crm_synced` fields are returned.

  ## Filtering

  Use query parameters to narrow results:

  * **`entity`** — return fields for a single entity (`contact` or `company`)
  * **`source`** — return only fields from a specific source (`default`, `custom`, or `crm_synced`)

  Both filters can be combined.
