Access to Termina API endpoints is secured using an HTTP Bearer token.
Use your API key to obtain a JWT Bearer token via the [Get Token](/api-reference/user/get-token) endpoint.
Include this token in the Authorization header of your requests to securely access your data.
The JWT contains user-specific roles granting permission to different resources.

## Request and Response Errors

| HTTP Status Code         | Description                                                                                              |
| ------------------------ | -------------------------------------------------------------------------------------------------------- |
| 401 Unauthorized         | The request lacks valid authentication credentials or the provided token is invalid.                     |
| 403 Forbidden            | The client does not have sufficient permission to access the requested resource.                         |
| 404 Not Found            | The requested resource could not be found.                                                               |
| 409 Conflict             | The request is trying to create or update a resource that already exists or has conflicting information. |
| 422 Unprocessable Entity | The request is well-formed but contains semantic errors.                                                 |

### Additional Information

If a client exceeds the rate limit, a `429: Too Many Requests` response will be returned.
JWTs created using your API key have a 1 hour expiration and will need to be [refreshed at regular intervals](/guide/common-code-patterns#refreshing-jwt-token-python-example) to avoid authentication errors.

## Permissions and Access Control

Access permissions are determined by the user roles associated with your API key.
The Termina API uses a role-based access control (RBAC) system with the following roles:

| Role   | Description                                                                         |
| ------ | ----------------------------------------------------------------------------------- |
| reader | Read-only access to resources (view deals, data, files, etc.)                       |
| editor | Read and write access (create/update deals, upload files, modify data)              |
| admin  | Full access including user management (add/remove team members, manage permissions) |

Your API key's role determines what actions you can perform across all groups and deals you have access to.
