## Batch create or replace origin cloud region mappings

`client.Cache.OriginCloudRegions.BulkUpdate(ctx, params) (*OriginCloudRegionBulkUpdateResponse, 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`.

### Parameters

- `params OriginCloudRegionBulkUpdateParams`

  - `ZoneID param.Field[string]`

    Path param: Identifier.

  - `Body param.Field[[]OriginCloudRegionBulkUpdateParamsBody]`

    Body param

    - `OriginIP 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 OriginCloudRegionBulkUpdateParamsBodyVendor`

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

      - `const OriginCloudRegionBulkUpdateParamsBodyVendorAws OriginCloudRegionBulkUpdateParamsBodyVendor = "aws"`

      - `const OriginCloudRegionBulkUpdateParamsBodyVendorAzure OriginCloudRegionBulkUpdateParamsBodyVendor = "azure"`

      - `const OriginCloudRegionBulkUpdateParamsBodyVendorGcp OriginCloudRegionBulkUpdateParamsBodyVendor = "gcp"`

      - `const OriginCloudRegionBulkUpdateParamsBodyVendorOci OriginCloudRegionBulkUpdateParamsBodyVendor = "oci"`

### Returns

- `type OriginCloudRegionBulkUpdateResponse struct{…}`

  Response result for a batch origin cloud region operation.

  - `Failed []OriginCloudRegionBulkUpdateResponseFailed`

    Items that could not be applied, with error details.

    - `OriginIP string`

      The origin IP address for this item.

    - `Error string`

      Error message explaining why the item failed. Present only on failed items.

    - `Region string`

      Cloud vendor region identifier. Present on succeeded items (the new value for upsert, the deleted value for delete).

    - `Vendor string`

      Cloud vendor identifier. Present on succeeded items (the new value for upsert, the deleted value for delete).

  - `Succeeded []OriginCloudRegionBulkUpdateResponseSucceeded`

    Items that were successfully applied.

    - `OriginIP string`

      The origin IP address for this item.

    - `Error string`

      Error message explaining why the item failed. Present only on failed items.

    - `Region string`

      Cloud vendor region identifier. Present on succeeded items (the new value for upsert, the deleted value for delete).

    - `Vendor string`

      Cloud vendor identifier. Present on succeeded items (the new value for upsert, the deleted value for delete).
