Hi! I'm using the REST API as described at http://www.amember.com/docs/REST_API_examples in order to import users from our old system. My problem here is that I need to assign the imported users to a particular group but I cannot figure out how this can be done through the REST API. Is there a way of doing?
No there is no way to do this yet. Why do you need this in first place? Currently groups are used for affiliate commission configuration only. There is no other real usage of groups in aMember yet.
