Custom connector to API with pagination

Hi, 

I am currentely trying to build a custom connector to an API using pagination. I have understood that I need to use Table.GenerateByPage(), however there are not any examples on how to do this for APIs that are not OData-ready. 

I receive the folowing metadata when the current page is not the current page:

And this if I am on the last page: 

So how do refer to the url marked <Link rel="next"?

The code when dealing with OData.Nextlink would typically begin like this: 

Page = (url as text) as nullable table =>
    let
        response = Web.Contents(url, [ Headers = BuildHeader()]),
        body = Json.Document(response),
        nextLink = GetNextLink(body),
        data = Table.FromRecords(body[next])
    in
        data meta [next = nextLink];

But what can I write instead of GetNextLink()?
