# v2.96.0 - Teslemetry PKCE Support

> New code_verifier field added to TeslemetryCreds schema across all connections and TMS-connections endpoints

**Released 14th October 2026**

## Teslemetry PKCE support

The `TeslemetryCreds` schema now includes an optional `code_verifier` field. This field supports PKCE (Proof Key for Code Exchange) flows where a code verifier is required as part of the Teslemetry OAuth token exchange.

The field is optional and backward-compatible — existing Teslemetry integrations that do not supply it are unaffected.

### Schema changes

| Field | Before | After |
| - | - | - |
| `code_verifier` | Not present | Optional string |

### Affected endpoints

All connections and TMS-connections endpoints that accept or return Teslemetry credentials are affected:

* `GET /v2/integrations/connections`
* `POST /v2/integrations/connections`
* `GET /v2/integrations/connections/{connection_id}`
* `PATCH /v2/integrations/connections/{connection_id}`
* `GET /v2/integrations/tms-connections`
* `POST /v2/integrations/tms-connections`
* `GET /v2/integrations/tms-connections/{tms_connection_id}`
* `PATCH /v2/integrations/tms-connections/{tms_connection_id}`

### Usage

If your Teslemetry application uses a PKCE flow, include the `code_verifier` in the credentials object:

```json theme={null}
{
  "credentials": {
    "provider": "teslemetry",
    "code_verifier": "your-pkce-code-verifier"
  }
}
```
