Syncing to an EPOS system using REST API

I am new to all this, I would like to display items for sale on my wix website, where the data comes from our existing epos system. The epos system has a REST API, so I guess it is possible to achieve.

I’m thinking that I should get the data in JSON format a few times a day and sync this to a dynamic shopping page? Is that what people normally do?

If so, could you give me a few pointers to start me off please? And if I am wrong, could you suggest a better way?

Thanks very much!

Have a look at Wix Fetch.

I saw that one thanks very much. Is this a usual way of working?
