I verify my webhook on postman using this code from the documentation:
GET https://www.your-clever-domain-name.com/webhooks?
hub.mode=subscribe&
hub.verify_token=mytoken&
hub.challenge=1158201444
But when launching the webhook verification for messenger from facebook.developpers , I got the error
"Impossible de valider l'url de rappel ou le jeton de validation. Veuillez verifier les informations fournies ou reessayer ultérieurement"
