Issue with Fetching more than 9K Records

Issue with Fetching more than 9K Records

Hi everyone,


I have implemented paging in the code as shown below. If the records are more than/equal to 9K, however, an application error says:


"http.status.internal_server_error:We are currently experiencing an issue with our service, please try again in a few minutes or contact Customer Support at" (We've contacted the email provided but have yet to receive a response.)


My question: How can we handle this issue if there are records exceeding 9K?


myContactlist = _contact.GetContacts(null, 500, modifiedsince, null);//to fetch all the records(active+optout)

                //myContactlist = _contact.GetContacts(null, 500, modifiedsince, ContactStatus.OPTOUT);

                //pagination to fetch the records >500

                var pagination = myContactlist.Meta.Pagination;


                //pagination to fetch the records >500

                // if there are more then 500 results, pagination.Next is populated

                // with the next URL to fetch

                while (pagination.Next != null)


                    ResultSet<Contact> morecontacts = _contact.GetContacts(modifiedsince, pagination);

                    myContactlist.Results = myContactlist.Results.Union(morecontacts.Results).ToList();

                    pagination = morecontacts.Meta.Pagination;




If I call this through the API, it also fails:



I've provided screenshots for your reference. Thanks for your time.

Hi Nick,


Thank you very much for this information. I have been researching your report of this issue and the symptoms match a known issue that is happening with one of our internal systems that powers the API. This issue has been escalated as a high priority and I am hopeful that we should be able to give a specific timeframe for resolution soon. If you have any questions or concerns, please let me know!
