## Replace Origin TLS Compliance Modes setting

`client.originTLSComplianceModes.update(OriginTLSComplianceModeUpdateParamsparams, RequestOptionsoptions?): OriginTLSComplianceModeUpdateResponse`

**put** `/zones/{zone_id}/settings/origin_tls_compliance_modes`

Replace the entire set of TLS compliance modes for the zone with the list provided in the request body. PUT performs a full replace, not a merge — any modes not present in the request body are removed. The request body must be of the form `{"value": ["fips", "pqh"]}`. Currently supported modes are `fips` and `pqh`; an empty list clears the constraint. Future modes (e.g. `cnsa2`) may be added; clients should treat unknown values as opaque strings. Invalid mode values are rejected with a 4xx response.

### Parameters

- `params: OriginTLSComplianceModeUpdateParams`

  - `zone_id: string`

    Path param: Identifier.

  - `value: Array<string>`

    Body param: List of TLS compliance modes that constrain the key-exchange algorithms Cloudflare may use when establishing the TLS connection to the zone's origin. Currently supported values are `fips` (FIPS-approved curves) and `pqh` (post-quantum hybrid). Future modes (e.g. `cnsa2`) may be added; clients should treat unknown values as opaque strings. Multiple modes are combined as the intersection of their permitted algorithm lists; selections whose intersection is empty are rejected. An empty list clears the constraint.

### Returns

- `OriginTLSComplianceModeUpdateResponse`

  - `id: "origin_tls_compliance_modes"`

    The identifier of the caching setting.

    - `"origin_tls_compliance_modes"`

  - `editable: boolean`

    Whether the setting is editable.

  - `value: Array<string>`

    List of TLS compliance modes that constrain the key-exchange algorithms Cloudflare may use when establishing the TLS connection to the zone's origin. Currently supported values are `fips` (FIPS-approved curves) and `pqh` (post-quantum hybrid). Future modes (e.g. `cnsa2`) may be added; clients should treat unknown values as opaque strings. Multiple modes are combined as the intersection of their permitted algorithm lists; selections whose intersection is empty are rejected. An empty list clears the constraint.

  - `modified_on?: string | null`

    Last time this setting was modified.

### 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 originTLSComplianceMode = await client.originTLSComplianceModes.update({
  zone_id: '023e105f4ecef8ad9ca31a8372d0c353',
  value: ['fips', 'pqh'],
});

console.log(originTLSComplianceMode.id);
```
