Webhook verification error in LINE

i am trying to config my bot to publish to line. After follow the instruction to copy the webhook url from kore to Line and click verify…then got this error. Please help

The webhook returned an HTTP status code other than 200.(400 Bad Request)

Confirm that your bot server returns status code 200 in response to the HTTP POST request sent from the LINE Platform. For more information, see Response in the Messaging API Reference


Please share the complete curl you are sending from line
Along with the headers and body
Also please share the client id and secret of your app (for webhook channel) with koresupport@kore.com
I hope the webhook channel is published.
