Request method update ---> is not working for custom field

[Giuseppe Iannacone]

I'm trying to update a custom field with the "update" method but got a response that the field was not expected, as far as I can understand from the documentation the value of the "customFields" parameter has to be a JSON object of the custom field to be updated, what am I doing wrong?

@Giuseppe Iannacone wrong payload. customFields is a string, not an object. Use this:

{
  "@service": "apps/com.hornbill.servicemanager/Requests",
  "@method": "update",
  "params": {
    "requestId":"{{request_ID}}",
    "h_external_ref_number":"-",
    "customFields":"{\"h_custom_p\": \"36\"}"
  }
}
