Create or update an origin cloud region mapping

PATCH/zones/{zone_id}/cache/origin_cloud_regions

Adds or updates a single IP-to-cloud-region mapping for the zone. Unlike POST, this operation is idempotent — if a mapping for the IP already exists it is overwritten. Returns the complete updated list of all mappings for the zone. Returns 403 (code 1164) when the zone has reached the limit of 3,500 IP mappings.
