API endpoint /v1/persons/:id

Hi,
I got a problem while using endpoint get a person’s details. It is about a custom field which should contain a value inside, but when I used the API to get data, that custom field was null.

I need to fix this asap, please. Thank you!

Please share bit more details to custom field to contain value.

My bad. It is the person field which is null. For more details, I have “d16cad683039dda92cd4f022c23886bb2f1cef2d” as key for field “Chức vụ”. On pipedrive, that field has value “Manager” but “d16cad683039dda92cd4f022c23886bb2f1cef2d” returned null when I use API endpoint /persons/:id
