Do Wix sites not natively support the Wix REST API?

Is there not a way to access the Velo API functions directly on your Wix website? For example, this call:

[https://dev.wix.com/api/rest/wix-stores/catalog/collections/create-collection](call:

It)

It looks like I have to create and register my own “Wix app” first, including hosting an OAuth server, then add that to my Wix site to gain the functionality. Is this accurate? I am pretty confused - does the Wix site not directly support this API? All I have been able to do is create a REST API in the wix stores backend, using javascript on the Wix site itself. The problem with this is that, there does not appear to be functionality to create collections in this way.

U need to do them separately and set up your own server / backend. It is not directly linked and I am sure Wix are working on to release full API in Velo

That is truly unfortunate. Thank you for the info.
