## Batch create or replace origin cloud region mappings `client.cache.originCloudRegions.bulkUpdate(OriginCloudRegionBulkUpdateParamsparams, RequestOptionsoptions?): OriginCloudRegionBulkUpdateResponse` **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` - `zone_id: string` Path param: Identifier. - `body: Array` Body param - `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" | "azure" | "gcp" | "oci"` Cloud vendor hosting the origin. Must be one of the supported vendors. - `"aws"` - `"azure"` - `"gcp"` - `"oci"` ### Returns - `OriginCloudRegionBulkUpdateResponse` Response result for a batch origin cloud region operation. - `failed: Array` Items that could not be applied, with error details. - `origin_ip: 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: Array` Items that were successfully applied. - `origin_ip: 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). ### Example ```node import Cloudflare from 'cloudflare'; const client = new Cloudflare({ apiToken: process.env['CLOUDFLARE_API_TOKEN'], // This is the default and can be omitted }); const response = await client.cache.originCloudRegions.bulkUpdate({ zone_id: '023e105f4ecef8ad9ca31a8372d0c353', body: [ { origin_ip: '192.0.2.1', region: 'us-east-1', vendor: 'aws', }, { origin_ip: '2001:db8::1', region: 'us-central1', vendor: 'gcp', }, ], }); console.log(response.failed); ``` #### Response ```json { "errors": [], "messages": [], "result": { "failed": [], "succeeded": [ { "origin_ip": "192.0.2.1", "region": "us-east-1", "vendor": "aws" }, { "origin_ip": "2001:db8::1", "region": "us-central1", "vendor": "gcp" } ] }, "success": true } ```
