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

`client.magicTransit.ipsecTunnels.pskSet(IPSECTunnelPSKSetParamsparams, RequestOptionsoptions?): 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

- `params: IPSECTunnelPSKSetParams`

  - `account_id: string`

    Path param: Identifier

  - `psks: Array<PSK>`

    Body param: List of tunnel ID and PSK pairs.

    - `id: string`

      The ID of the IPsec tunnel.

    - `psk: string`

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

  - `validate_only?: boolean`

    Query param: If `true`, only run validation without persisting changes.

### Returns

- `IPSECTunnelPSKSetResponse`

  - `successfully_applied_psks?: Record<string, SuccessfullyAppliedPSKs>`

    Map of tunnel IDs to successfully applied PSK details.

    - `ipsec_id: string`

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

    - `ipsec_tunnel_id: string`

      Identifier

    - `psk: string`

      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?: string`

        The date and time the tunnel was last modified.

  - `unapplied_psks?: Record<string, string>`

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

### Example

```node
import Cloudflare from 'cloudflare';

const client = new Cloudflare({
  apiToken: process.env['CLOUDFLARE_API_TOKEN'], // This is the default and can be omitted
});

const response = await client.magicTransit.ipsecTunnels.pskSet({
  account_id: '023e105f4ecef8ad9ca31a8372d0c353',
  psks: [{ id: '023e105f4ecef8ad9ca31a8372d0c353', psk: 'O3bwKSjnaoCxDoUxjcq4Rk8ZKkezQUiy' }],
});

console.log(response.successfully_applied_psks);
```
