Within the main HTTP request, each\npart contains a nested HTTP request.\n\nYou can send the batch request to the specified `batchPath` for the API. The\n`batchPath` for Merchant API is `batch/{sub-api}/v1`. You can find the\n`batchPath` for other APIs in their [discovery\ndocuments](/discovery/v1/reference/apis).\n\nExamples of reasons to batch your requests include:\n\n- You just started using the API and have a lot of data to upload.\n- A user made changes to data while your application was offline, and your application needs to synchronize local data with the server.\n\nSending multiple requests in parallel prevents you from waiting for the slowest\nsub-request, which improves server response times and reduces latency.\n| **Tip:** For optimal performance of high-throughput tasks like product or inventory updates, we recommend starting with a moderate batch size and then scaling based on your API quota. For the API-specific quotas, see [Quota and\n| limits](/merchant/api/guides/quotas-limits)\n| **Note:** Batching requests doesn't reduce your usage count. If a batch has N individual requests, it counts as N requests against your quota.\n\nWrite a batch request\n\nHere's a sample Merchant API batch request. This request combines a get request\nto retrieve the regional inventory for a product, and an insert request to\nupdate the regional inventory for the same product. You should follow the format\nof the example exactly:\n\n1. Use `https://merchantapi.googleapis.com/batch/{sub-api}/v1` as the base URL.\n2. Specify a boundary to separate each nested request, for example: `-H\n 'Content-Type: multipart/mixed,boundary=batch_inventory' \\`\n3. Separate each nested request with the boundary, for example `--batch_inventory`.\n4. Include `Content-Type: application/http` at the beginning of each nested request.\n5. Use `Content-ID` to label each nested request with your own ID. For example: `Content-ID: \u003cget~en~US~123456\u003e`.\n6. Include a blank line between the header, path and body of each nested request. If the nested request doesn't have a body, leave a blank line before the next boundary.\n7. Don't include the base URL in each individual nested request.\n8. End the main request with a final boundary, for example `--batch_inventory--`.\n\n curl https://merchantapi.googleapis.com/batch/inventories/v1 \\\n -H 'Authorization: Bearer \u003cTOKEN\u003e' \\\n -H 'Content-Type: multipart/mixed,boundary=batch_inventory' \\\n --data '\n --batch_inventory\n Content-Type: application/http\n Content-ID: \u003cget:online:en:US:123456\u003e\n GET /inventories/v1/accounts/123/products/online:en:US:123456/regionalInventories\n --batch_inventory\n Content-Type: application/http\n Content-ID: \u003cpost:online:en:US:123456\u003e\n POST /inventories/v1/accounts/123/products/online:en:US:123456/regionalInventories:insert\n {\n \"region: \"123456\",\n \"price\": {\n \"amountMicros\": \"100000000\",\n \"currencyCode\": \"USD\"\n }\n }\n --batch_inventory--\n '\n\nNotes on ordering\n\n- Requests might not execute in the order you specify them.\n- Use `Content-ID` to identify individual requests.\n- If you need to execute your calls in a given order, send them separately and wait for the response to the first request before sending the next one.\n\nRead a batch response\n\nHere's an example of an HTTP batch response. The order of the responses might\nnot match the order of the requests. Use `Content-ID` to identify the nested\nrequest each nested response belongs to. In the responses, the API adds a\n`response-` prefix to each `Content-ID`. \n\n --batch_inventory\n Content-Type: application/http\n Content-ID: \u003cresponse-get~en~US~123456\u003e\n HTTP/1.1 200 OK\n Content-Type: application/json; charset=UTF-8\n Vary: Origin\n Vary: X-Origin\n Vary: Referer\n {}\n --batch_inventory\n Content-Type: application/http\n Content-ID: \u003cresponse-post~en~US~123456\u003e\n HTTP/1.1 200 OK\n Content-Type: application/json; charset=UTF-8\n Vary: Origin\n Vary: X-Origin\n Vary: Referer\n {\n \"name\": \"accounts/123/products/en~US~123456/regionalInventories/123456\",\n \"region\": \"123456\",\n \"price\": {\n \"amountMicros\": \"100000000\",\n \"currencyCode\": \"USD\"\n }\n }\n --batch_inventory--\n '"]]
