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

`client.MagicTransit.IPSECTunnels.PSKSet(ctx, params) (*IPSECTunnelPSKSetResponse, error)`

**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`

  - `AccountID param.Field[string]`

    Path param: Identifier

  - `PSKs param.Field[[]IPSECTunnelPSKSetParamsPSK]`

    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.

  - `ValidateOnly param.Field[bool]`

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

### Returns

- `type IPSECTunnelPSKSetResponse struct{…}`

  - `SuccessfullyAppliedPSKs map[string, IPSECTunnelPSKSetResponseSuccessfullyAppliedPSK]`

    Map of tunnel IDs to successfully applied PSK details.

    - `IPSECID string`

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

    - `IPSECTunnelID string`

      Identifier

    - `PSK string`

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

    - `PSKMetadata PSKMetadata`

      The PSK metadata that includes when the PSK was generated.

      - `LastGeneratedOn Time`

        The date and time the tunnel was last modified.

  - `UnappliedPSKs map[string, string]`

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

    AccountID: cloudflare.F("023e105f4ecef8ad9ca31a8372d0c353"),
    PSKs: cloudflare.F([]magic_transit.IPSECTunnelPSKSetParamsPSK{magic_transit.IPSECTunnelPSKSetParamsPSK{
      ID: cloudflare.F("023e105f4ecef8ad9ca31a8372d0c353"),
      PSK: cloudflare.F("O3bwKSjnaoCxDoUxjcq4Rk8ZKkezQUiy"),

  }
  fmt.Printf("%+v\n", response.SuccessfullyAppliedPSKs)
}
