# Product BATCH update

This endpoint allows you to update multiple products at once. Batch
update is processed asynchronously in same way as for example products
snapshot,

but it does not have  with products to download in response.
Instead, you can check attribute  which contains successfully
updated products and errors.


See how [Asynchronous
requests](https://developers.shoptet.com/asynchronous-requests/) work on
our developer's portal.


File with data for update must be in JSONL
(jsonlines) format. Each line must contain one
product in JSON format. Maximum size of file is 100MB.

Structure of JSON row is same as structure of JSON for single product
update above. You can add one extra optional attribute

"language" which defines language of updating product, so you are able
to update multiple language attributes (i.e. "name", "description" etc.)
of one product in one batch file.

If language is not defined, default language of shop is used.


Asynchronous job process jsonl file row by row and try to validate and
save data. If there is any error, row is skipped and error is logged,
but it does not stop processing of other rows.

In Log, every product is identified by its position in file (starting
from 1).
