## Set Pre-Shared Keys (PSK) for IPsec tunnels

`magic_transit.ipsec_tunnels.psk_set(IPSECTunnelPSKSetParams**kwargs)  -> IPSECTunnelPSKSetResponse`

**post** `/accounts/{account_id}/magic/ipsec_tunnels/psk`

Sets Pre-Shared Keys for multiple IPsec tunnels associated with an account. Use `?validate_only=true` as an optional query parameter to only run validation without persisting changes. After PSKs are applied, they are immediately persisted to Cloudflare's edge and cannot be retrieved later. Store the PSKs in a safe place.

### Parameters

- `account_id: str`

  Identifier

- `psks: Iterable[PSK]`

  List of tunnel ID and PSK pairs.

  - `id: str`

    The ID of the IPsec tunnel.

  - `psk: str`

    A randomly generated or provided string for use in the IPsec tunnel.

- `validate_only: Optional[bool]`

  If `true`, only run validation without persisting changes.

### Returns

- `class IPSECTunnelPSKSetResponse: …`

  - `successfully_applied_psks: Optional[Dict[str, SuccessfullyAppliedPSKs]]`

    Map of tunnel IDs to successfully applied PSK details.

    - `ipsec_id: str`

      The IKE identifier used for this tunnel on the Cloudflare edge.

    - `ipsec_tunnel_id: str`

      Identifier

    - `psk: str`

      A randomly generated or provided string for use in the IPsec tunnel.

    - `psk_metadata: PSKMetadata`

      The PSK metadata that includes when the PSK was generated.

      - `last_generated_on: Optional[datetime]`

        The date and time the tunnel was last modified.

  - `unapplied_psks: Optional[Dict[str, str]]`

    Map of tunnel IDs to failure reasons for PSKs that could not be applied.

### Example

```python
import os
from cloudflare import Cloudflare

client = Cloudflare(
    api_token=os.environ.get("CLOUDFLARE_API_TOKEN"),  # This is the default and can be omitted
)
response = client.magic_transit.ipsec_tunnels.psk_set(
    account_id="023e105f4ecef8ad9ca31a8372d0c353",
    psks=[{
        "id": "023e105f4ecef8ad9ca31a8372d0c353",
        "psk": "O3bwKSjnaoCxDoUxjcq4Rk8ZKkezQUiy",
    }],
)
print(response.successfully_applied_psks)
```
