Looping through paginated API query without known total - help pulling pages 2+

So your current query returns a list with just one row?

Then adjust the query like so and check the error-message that will be generated (then) for the 2nd item in the list:

let
Pagination = List.Skip(List.Generate(
() => [Last_Key = "init", Counter=0], // Start Value
each [Last_Key] <> null or [Counter] < 4, // Condition under which the next execution will happen
each [ Last_Key = try if [Counter]<1 then "" else [WebCall][Value][page] otherwise null,// determine the LastKey for the next execution
WebCall = try if [Counter]<1 then Json.Document(Web.Contents("https://community.website.com/api/v2/users", [Headers=[Authorization="Bearer TOKEN"]])) else Json.Document(Web.Contents("https://community.website.com/api/v2/users/?page="&Last_Key&"", [Headers=[Authorization="Bearer TOKEN"]])), // retrieve results per call
Counter = [Counter]+1// internal counter
],
each [WebCall]
),1)
