Retrieve null value in json for integer type in Outsystems
Question

I am writing an API to expose Outsystems data to an external system in JSON. We have a number field retrieved from that API which can be a numeral integer value including zero. Zero is not considered a null value in the external system. Is there any value I can set in the field so that a null value is retrieved in JSON?

Thanks Benjith

Hi Desiree,

The only way I'm seeing is to change the field type to text and add your logic to check if you should send 0 or ''.

Hope it helps,

Yes. Thanks. I am already checking for 0s and null strings on the on-response action. The issue is resolved.
