Make sure whatsapp-bot
service is accessible using public domain host address(with port number in the host). Because Gupshup webhook will only allow to set the webhook public host URL endpoint.
ex:https://eJP.sunbird.org/api/whatsapp/webhook
which is redirecting to whatsapp-bot
service url by API Manager
ex: https://<remote-ip>:3010/gupshup/webhook
