Create an origin cloud region mapping

client.Cache.OriginCloudRegions.New(ctx, params) (*OriginCloudRegionNewResponse, error)

POST/zones/{zone_id}/cache/origin_cloud_regions

Adds a single IP-to-cloud-region mapping for the zone. The IP must be a valid IPv4 or IPv6 address and is normalized to canonical form before storage (RFC 5952 for IPv6). Returns 400 (code 1145) if a mapping for that IP already exists — use PATCH to update an existing entry. The vendor and region are validated against the list from GET /zones/{zone_id}/cache/origin_cloud_regions/supported_regions.

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
