Remove Leads from List using SOAP and REST APIs Hi,Recently we cannot remove leads from list using the RemoveLeadsFromList REST API with a POST request of "application/x-www-form-urlencoded" contentType, listId and leadIds in the request Url, _method=DELETE , the error code is 612(Invalid Content Type), does anyone have the same problem?(the code used to work fine before, I try to check but seems there's nothing change in the code, but I might be not 100% sure).Then we switched to SOAP to perform the same action using ListOperation API(listOperation=REMOVEFROMLIST, listKey->keyType=MKTOLISTNAME), and encountered another problem: if the listKey->keyValue has some kind of special character( e.g: Chương trình List), an exception occurs: 20111 - List not foundSeems like some encoding is needed here, I've just tried Url encoding the value but it does not work either.Any help would be greatly appriciated!Thanks!
