Link filter query with add rank button


We try to create boards with greenhopper library, and we are not able to link our filters with RANK field (ADD RANK).

We used the GreenHopper Service (rankCustomFiledService) to get or create our rank field in our filter query, but unfortunately the results are not the same as when you clicked on the “add rank button”.

Do you know a service which can permit us to automate the add rank button role ?
