# Change Origin TLS Compliance Modes setting

origin\_tls\_compliance\_modes.edit(OriginTLSComplianceModeEditParams\*\*kwargs) -> [OriginTLSComplianceModeEditResponse](<https://developers.cloudflare.com/api/python/resources/origin_tls_compliance_modes#(resource)%20origin_tls_compliance_modes%20%3E%20(model)%20origin_tls_compliance_mode_edit_response%20%3E%20(schema)>)

PATCH/zones/{zone\_id}/settings/origin\_tls\_compliance\_modes

Update the set of TLS compliance modes for the zone. PATCH performs a full replace of the modes list, not a merge — the request body is treated as the complete new list, and any modes not present in it are removed. (To remove a single mode from an existing configuration, send the updated list without it.) 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.

##### Security

<details>

<summary>API Token</summary>



The preferred authorization scheme for interacting with the Cloudflare API. <a href="https://developers.cloudflare.com/fundamentals/api/get-started/create-token/">Create a token</a>.

**Example:**<code>Authorization: Bearer Sn3lZJTBX6kkg7OdcBUAxOO963GEIyGQqnFTOFYY</code>

</details>

<details>

<summary>API Email + API Key</summary>



The previous authorization scheme for interacting with the Cloudflare API, used in conjunction with a Global API key.

**Example:**<code>X-Auth-Email: user@example.com</code>

The previous authorization scheme for interacting with the Cloudflare API. When possible, use API tokens instead of Global API keys.

**Example:**<code>X-Auth-Key: 144c9defac04969c7bfad8efaa8ea194</code>

value: Sequence\[str]

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.
