--- title: Create or replace an origin cloud region mapping --- [Skip to content](#_top) [API Reference](https://developers.cloudflare.com/api/python) [Cache](https://developers.cloudflare.com/api/python/resources/cache) [Origin Cloud Regions](https://developers.cloudflare.com/api/python/resources/cache/subresources/origin_cloud_regions) Copy Markdown Open in **Claude**Open in **ChatGPT**Open in **Cursor** --- **Copy Markdown****View as Markdown** # Create or replace an origin cloud region mapping cache.origin\_cloud\_regions.update(strpath\_origin\_ip, OriginCloudRegionUpdateParams\*\*kwargs) -> [OriginCloudRegionUpdateResponse]() PUT/zones/{zone\_id}/origin/cloud\_regions/{origin\_ip} Creates a new IP-to-cloud-region mapping or replaces the existing mapping for the specified IP. PUT is idempotent — calling it repeatedly with the same body produces the same result. The IP path parameter is normalized to canonical form (RFC 5952 for IPv6) before storage. The vendor and region are validated against the list from `GET /zones/{zone_id}/origin/cloud_regions/supported_regions`. Returns 400 if the `origin_ip` in the body does not match the URL path parameter. Returns 403 (code 1164) when the zone has reached the limit of 3,500 IP mappings. ##### Security

API Token

The preferred authorization scheme for interacting with the Cloudflare API. Create a token. **Example:**Authorization: Bearer Sn3lZJTBX6kkg7OdcBUAxOO963GEIyGQqnFTOFYY

API Email + API Key

The previous authorization scheme for interacting with the Cloudflare API, used in conjunction with a Global API key. **Example:**X-Auth-Email: user@example.com The previous authorization scheme for interacting with the Cloudflare API. When possible, use API tokens instead of Global API keys. **Example:**X-Auth-Key: 144c9defac04969c7bfad8efaa8ea194
