# Batch requests

Use Batch requests to send **up to 500** API calls to Ecwid, thus increasing your server performance. Such requests are most useful when you need to send multiple requests of a similar nature, for example, update the product stock for 400 products.

{% hint style="info" %}
Separate batch requests for the same store use the **FIFO sequence**. Until the earlier batches are fully processed, the later ones will not start.\
\
The same **FIFO sequence** applies to all API calls inside one batch. For example, if an API call inside a batch deletes a product, the next call won't be able to update this product as it has already been deleted.
{% endhint %}

You can further speed up the completion of batch requests by passing the `allowParallelMode=true` query param. In that case, up to **100** requests from your batch will be processed simultaneously.
