Hi @Ajith 9655,

Is there any error popup’s ? 

Add the message box before post the data and verify the data if is correct format or not

Hi @Tamil Arasu10 , We didn’t get any popups. If we hardcoded it works, but not working by passing as parameter.

Hi @Ajith 9655,

Please check the Headers details 

Add any necessary headers (e.g., Content-Type: application/json)

Paste your JSON payload in the body section

{
  "values": {
    "Work Log Type": "Customer Communication",
    "Detailed Description": "$detaildescrption$",
    "Work Log Submitter": "MFDM",
    "Incident Number": "$vIncidentId$"
  }
}

I hope this will works for you.
