Configure Web Api Connection Several Request

Hello Holguinmora 

saw that you opened this topic twice...

as you passed me your credentials, I was able to develop something for your. I've tested it and it should work. Here the code

let
    Final = List.Generate
    (
        ()=>
        [
            Result= Json.Document(Web.Contents("https://api.repsly.com/v3/export/clients/0", [Headers=[Accept="application/json"]])),
            TotalCount = 1
    

        ],
        each [TotalCount]>0,
        each 
        [
            
            Result= Json.Document(Web.Contents("https://api.repsly.com/v3/export/clients/" & Text.From([Result][MetaCollectionResult][LastTimeStamp]), [Headers=[Accept="application/json"]])) ,
            TotalCount = [Result][MetaCollectionResult][TotalCount]
             

        ],

        each [Result][Clients]
    ),
    FinalTable = Table.FromRecords(List.Combine(Final))
in
    FinalTable
