## Authentication

This endpoint accepts any one of the following token types:

- **Company-scoped access token** (`OAuth2AuthorizationCode`) — obtained by a company manager through the Authorization Code flow or the Refresh Token flow. See [Authentication for partners](https://developer.remote.com/docs/authentication-for-partners).
- **Company-scoped access token (assertion)** (`OAuth2CompanyManagerAssertion`) — obtained through the `urn:ietf:params:oauth:grant-type:jwt-bearer` grant for a company manager. See [OAuth Assertion](https://developer.remote.com/docs/authorization-method-oauth-assertion).
- **Customer API token** (`CustomerAPIToken`) — generated by the customer on their Integration Settings page, with the scopes they choose there. See [Authorization for customers](https://developer.remote.com/docs/authorization-for-customers).

## Scopes

Any one of the scopes in a token type's row is enough. `all:write` works too.

| Token type | Category | Read only Scope | Write only Scope (read access implicit) |

| Company-scoped access token | Manage employments (`employments`) | - | Manage custom fields (`custom_field:write`) |
| Company-scoped access token (assertion) | Manage employments (`employments`) | - | Manage custom fields (`custom_field:write`) |
