FAQ

Comment envoyer des messages à plusieurs numéros de téléphone

Vous devez envoyer de nombreuses requêtes API, une par numéro de téléphone cible.

Par exemple, pour envoyer un message à 10 numéros, vous devez envoyer 10 requêtes HTTPS indépendantes à l'API.

Il n'existe pas d'option pour envoyer plusieurs messages dans une seule requête API.

Comment valider si un numéro de téléphone peut recevoir des messages WhatsApp

Vous pouvez valider si un numéro de téléphone donné est lié à un compte WhatsApp et peut recevoir des messages.

L'API fournit un point de terminaison pour valider si un numéro de téléphone donné existe sur WhatsApp.

La seule exigence est d'avoir au moins un numéro WhatsApp connecté à la plateforme dans votre compte actuel.

Pour plus de détails, veuillez consulter la documentation du point de terminaison de l'API ici.

Avant de vérifier si un numéro existe sur WhatsApp, vous pouvez également valider et normaliser le format d'une liste de numéros de téléphone en utilisant le point de terminaison de validation de numéros. Ce point de terminaison ne valide que le format correct E164 mais ne vérifie pas si le numéro est effectivement sur WhatsApp.

Remarque : le nombre de validations de disponibilité WhatsApp est limité par mois en fonction de votre plan d'abonnement. Veuillez consulter le tableau de tarification pour plus de détails sur les limites.
