Hi, 
  Im trying to enable a webhook in python with this code, but  Im just having this error : 
disabledDetails": "Response was missing verification response in both header and body, or body JSON may have been invalid. (ref id: latvtu)", "enabled": false
    
        
            
    
in that sense, I think that the callback url is well configured because when I runing the previous code to activate the webhook, an aws lambda function is triggered that has that url created in aws´s apigateaway which gives this log
    
        
            
    
As you can see it, the Smartsheet-Hook- Response is not in the header that the webhook sent, however I run this code in aws lambda that should handle that case that the challenge is not in that header but in the body, :
import json
def lambda_handler(event, context):
print("Evento completo recibido:", json.dumps(event))
if "challenge" in event:
    challenge = event.get("challenge")
   # Respond to verification challenge
return {
                "statusCode": 200,
                "headers": {
                    "Content-Type": "application/json",
                    "Smartsheet-Hook-Response": challenge  # Enviar desafío en el encabezado
                },
                "body": json.dumps({"smartsheetHookResponse": challenge})
    print("Respuesta enviada:", json.dumps(response))
return {
    'statusCode': 200,
    'body': 'Data received and processed successfully
but It did not work either, can any of you could guide me how to solve this. I tried another version of that code that I saw on internet but cant reach a solution.
grateful in advance.
greetings.
