## Batch create or replace origin cloud region mappings

**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`.

### Path Parameters

- `zone_id: string`

  Identifier.

### Body Parameters

- `body: array of object { origin_ip, region, vendor }`

  - `origin_ip: string`

    Origin IP address (IPv4 or IPv6). For the single PUT endpoint (`PUT /origin/cloud_regions/{origin_ip}`), this field must match the path parameter or the request will be rejected with a 400 error. For the batch PUT endpoint, this field identifies which mapping to upsert.

  - `region: string`

    Cloud vendor region identifier. Must be a valid region for the specified vendor as returned by the supported_regions endpoint.

  - `vendor: "aws" or "azure" or "gcp" or "oci"`

    Cloud vendor hosting the origin. Must be one of the supported vendors.

    - `"aws"`

    - `"azure"`

    - `"gcp"`

    - `"oci"`
