Updated: Feb 10, 2026

Reading

You can’t perform this operation on this endpoint.

Creating

/{product_catalog_id}/localized_items_batch

You can make a POST request to localized_items_batch edge from the following paths:
When posting to this edge, no Graph object will be created.
The sample API call provides an example of how this API endpoint works in practice.

Limitations

  • This endpoint does not create new catalog items. All requests should contain a data JSON object that contains an ID for an existing catalog item.
  • The requests param can contain up to 5,000 items.
  • For each catalog, you can make a number of calls per minute defined by the Catalog Batch business use case rate limit formula. If that's not sufficient, please contact us.
  • Error code 1 with message "Please reduce the amount of data you're asking for, then retry your request" indicates that the size of the data (in bytes) received in API request is too large. To fix this issue, please reduce the number of items in the batch and try again. This will ensure that the request is within the acceptable size limits and can be processed successfully.

Parameters

Parameter Description
item_type
string
The type of items in the request. Needs to be one of the values listed here. Note that the information specified in this field is NOT a product category (a concept used for item_type=PRODUCT_ITEM).

requests
JSON object
A JSON array of up to 5000 records, each containing 3 fields:
  • method: one of CREATE/UPDATE/DELETE
  • data: a map containing product field names and the corresponding values. The list of fields supported in product localization is given here. The descriptions of the fields can be found on the /items_batch endpoint documentation page.
    Note: price, sale_price, unit_price, base_price, status (visibility), and availability must only be provided in a country feed. These fields cannot be provided in a language feed. This helps ensure customers see the correct localized product data.
    • When the method is CREATE, this object must contain all the required fields for the specified item_type.
    • When the method is UPDATE, it can contain any fields.
    • A request with method=DELETE is expected to contain only the 'id' field
  • localization: a map containing the following two values:
    • type: Supported values: LANGUAGE, COUNTRY, or LANGUAGE_AND_COUNTRY
    • value: Can be any valid language or county code, depending on the selected type. Note that for LANGUAGE_AND_COUNTRY, the values should be separated by a '|' character, for example, en_XX|US. See a list of language and country codes here⁠.
