# Batch create or replace origin cloud region mappings

client.Cache.OriginCloudRegions.BulkUpdate(ctx, params) (\*[OriginCloudRegionBulkUpdateResponse](<https://developers.cloudflare.com/api/go/resources/cache#(resource)%20cache.origin_cloud_regions%20%3E%20(model)%20OriginCloudRegionBulkUpdateResponse%20%3E%20(schema)>), error)

PUT/zones/{zone\_id}/origin/cloud\_regions/batch

Upserts up to 100 IP-to-cloud-region mappings in a single request. Items in the request body are created or replaced; mappings not included in the request body are preserved unchanged (this is a merge operation, not a full collection replacement). Each item is validated independently — valid items are applied and invalid items are returned in the `failed` array. The vendor and region for every item are validated against the list from `GET /zones/{zone_id}/origin/cloud_regions/supported_regions`.
