Activer/Installer une solution dans Sharepoint Online (Sitecollection -> Webtemplate)

Question

J'essaye de déclencher à l'aide d'un Webrequest, un bouton dans Sharepoint Online.

Le premier Errro-Code:

Exception appelant "GetResponse" avec "0" argument (s): "Le serveur distant a renvoyé une erreur: (403) interdite."

$solutionId = Get-SPOSolutionId -solutionName $solutionName

Answer 1

Avez-vous ajouté votre point de terminaison externe dans le fichier manifeste. Vous devez ajouter l'URL du point de terminaison afin que l'application dispose des autorisations nécessaires pour accéder au point de terminaison externe.

Voici un lien avec un exemple de code pour exécuter/interroger des points de terminaison externes et d'autres sources telles que: application web, application hôte ou collections de sites ... etc.
