Set Up SharePoint Server Client
This manual is relevant only for on premises SharePoint Server. If you want to configure SharePoint Online please refer to Set Up SharePoint Online and OneDrive.
In the context of this connector you need to make sure that amberSearch has access to the SharePoint Server network-wise. The APIs are called in the context of service account. In the following you can see how to create the service account and grant the required permissions. amberSearch needs to navigate through the folders and files, pages and read them. Furthermore amberSearch should be able to read the permissions structure in order to ensure that the users can search through the contents that they are permitted to.
Create a new user (we refer to it as service account in this manual). If SharePoint Server is relying on a local Active Directory, then you can create the user in AD as well
Grant the user at least the following permissions
Hint: You can create a new permission level that complies with our requirements, if you do not have existing ones that fit with the requirements above. Below you see an example of permission level that matches amberSearch needs.

By default, amberSearch will integrate the root / site collection. If you have multiple sites collections, make sure that the service account has the respective rights/permissions in all relevant site collections.
Check List

SharePoint Server URL and IP
