Afin de connecter les sources de données Salesforce, votre utilisateur Salesforce a besoin d'un profil qui :
SalesForce exige certaines autorisations au niveau de l'application pour permettre l'accès à l'API.
Pour utiliser l'API, votre organisation doit être sur l'une des 4 éditions suivantes (l'API est activée par défaut) : Enterprise Edition, Unlimited Edition, Developer Edition, Performance Edition
Les éditions sans accès à l'API sont : Contact Edition, Group Edition, Professional Edition, Spark Edition
Notes sur l'API (source : salesforce.com) :
Beginning with the Winter '15 Release, API cannot be activated for Contact Manager or Group Editions, even for migration purposes. Please contact your Account Executive if you would like to upgrade your edition to Enterprise or higher.
For Professional Edition organizations, all requests for API access must be purchased and can be processed contacting your Account Executive.
If you need the API enabled for a Data Migration to a Professional Edition organization, you will need to contact your Account Executive and request that API be provisioned as courtesy. These requests should be for Data Migrations only and will be up to you and your Account Executive to determine the time frame of the API enabled.
