Pipeline & SubPipeline datas missing when record created by the function zoho.bigin.createRecord

Hi
When I use the zoho.bigin.createRecord function to create a deal, I get a sucess status code in response.
But unlike manually created records, the Sub Pipeline is not saved when I use the Bigin function (even though the data is present at the input of the request).
What's wrong?
