We use the "Group Edition" and get "API_DISABLED_FOR_ORG: API is not enabled for this Organization or Partner" using SOAP.
We are trying to search if a user exist as a contact in Salesforce based on email. All we need is a confirmation, true/false.
We found this documentation https://developer.salesforce.com/docs/atlas.en-us.packagingGuide.meta/packagingGuide/dev_packages_api_access.htm
From my understanding of that, what we wanna do should be possible. Is that so? If so, how? If not, what do we need to do to get this to work?
