Track changes on website

Hi guys,

I am interested in som how I can track changes on any website e.g. e-shop and track change on the element. For example, I want to get notification when price will be changed.

I think, that it can be done via Cron trigger (every hour) => http request to the website => parse html => compare the value with the old one.

I found, that there is a function called https://docs.n8n.io/#/nodes?id=method-getworkflowstaticdatatype for storage small data and I want to ask you, if there is no better way for this type of use.

Thank you very much.

If you want to store larger amounts of data the static-data is really not a good option. It is then better to simply store in some kind of external datastore like Postgres, Redis, MySql, Airtable, Google Sheets, … or even a simple local file. For all the mentioned possibilities nodes exist already and should so not be too complicated to set it up.

I hope that helps!

Thank you for the confirmation :slight_smile:

Sure always happy to help. Have a great weekend!
