Can I grant Screenful access only to specific data sources?
Data sources are authorised when they are created. Screenful will have access to the same boards as the user that is doing the authorisation. To limit which data sources Screenful can access, you should authorise the data sources with a user that has access only to those data sources that you want Screenful to see. This could be a normal user that happens to have access to the right data sources or it could be user created specifically for the purpose of authorising the Screenful integration.
