Bulk Product Updates

Bulk product updates can be done by building a custom Magento shell command. Below is an example of a Magento shell command. The following command loads the most recently 100 updated products and bulk updates them to Nosto.

Please note that in order to use the example implementation below you must have at least 2.10.0 of the Nosto extension installed in your store.

Once placed into the shell directory of your Magento installation, the following command invokes the process.

php -f nostoProductUpdate.php

We do not recommend updating products in batches of more than 100 at a time. If you exceed this limit, you might hit the hard limits of maximum POST request size of 2MB.

FAQ

Do I need to send my entire catalog with every cron update?

No, if possible, only send the products that have changed.

How many products can I send in one update?

You may send as many products as you want so long as the entire payload is under 2MB. We recommend starting off with a batch sizes of 50 and tweaking as you go along.

How often should I run the cron?

Crons should be run as often as you synchronise catalog data. Failure to do so may result in incorrect or invalid products being recommended.

How should discontinued products be handled?

In order to flag products as discontinued, you will need to deduce what those products are and sync those. Any product that out-of-stock, discontinued, invisible or unavailable (for whatever reason), will not be recommended by Nosto.
