Connexion Sharepoint (office365)
Bonjour,
Je cherche actuellement une façon d'implémenter une connexion à un sharepoint (office365). J'ai déjà essayé différentes choses sans succès et j'ai l'impression que je tourne en rond sur des technologies que je ne connais pas bcp.
Pouvez-vous me donner des idées d'implémentations ou même un code déjà fait ?
Merci de l'aide que vous pouvez me donner.
Différents essais :
Là j'obtiens une erreur 403 Forbidden.
