# v2.44.0 - Three MD Provider Support

> New telematics service provider added to the Integrations API

**Released 21st August 2026**

## Three MD Provider Support

This release adds support for **Three MD** (`three_md`) as a new telematics service provider across all Integrations API endpoints.

<Check>
  **Backward-compatible addition:** Existing integrations are unaffected. The `three_md` value is additive to the `source_name` enum and requires no migration.

### New Provider Support

<AccordionGroup>
  <Accordion title="Three MD added to source_name enum" icon="sparkles">
    The `three_md` value has been added to the `source_name` / `TspEnum` enumeration. This new value is now accepted and returned across all Integrations API endpoints that reference a telematics service provider.

    **Affected endpoints:**

    | Method | Endpoint |
    | - | - |
    | `GET` | `/v2/integrations/connections` |
    | `POST` | `/v2/integrations/connections` |
    | `GET` | `/v2/integrations/connections/{connection_id}` |
    | `PATCH` | `/v2/integrations/connections/{connection_id}` |
    | `GET` | `/v2/integrations/connections/{connection_id}/schedules/{schedule_id}/executions` |
    | `GET` | `/v2/integrations/connections/{connection_id}/resource-operations/{resource_operation_id}` |
    | `GET` | `/v2/integrations/connections/resource-operations` |
    | `GET` | `/v2/integrations/tsps` |
    | `GET` | `/v2/integrations/tsps/{tsp_id}` |

    **Filtering by Three MD:**

    ```bash theme={null}
    # List connections for Three MD
    GET /v2/integrations/connections?source_name=three_md

    # List resource operations for Three MD
    GET /v2/integrations/connections/resource-operations?source_name=three_md
    ```

    **Example response:**

    ```json theme={null}
    {
      "items": [
        {
          "id": "conn_abc123",
          "source_name": "three_md",
          "status": "active"
        }
      ]
    }
    ```
  </Accordion>
