Add Community members via Apex?

Question

Is it possible to add/change/delete Community members using Apex? I know how to do this via the UI (see picture below), but I'm looking to automate some things on the demo side of the business for our sales reps.

Although Salesforce says 'create' allowed on Network Member: https://developer.salesforce.com/docs/atlas.en-us.api.meta/api/sforce_api_objects_networkmember.htm, but seems that not allowed using apex code. No worries, we can make a post REST call for the same:

First add your salesforce base url as remote site setting then add this code as part of your implementation:

        String endpoint = URL.getSalesforceBaseUrl().toExternalForm()+'/services/data/v47.0/sobjects/NetworkMemberGroup';
        HttpRequest httpRequest = new HttpRequest();  
        httpRequest.setEndpoint(endpoint);  
        httpRequest.setMethod('POST'); 
        httpRequest.setHeader('Authorization', 'Bearer ' + UserInfo.getSessionID()); 
        httpRequest.setHeader('Content-Type', 'application/json;charset=UTF-8'); 

        //Change network id and profile/permission set Id
httpRequest.setBody('{"NetworkId":"0DB900000008Qga","ParentId":"00e90000001uNre"}');
        Http http = new Http();
        HttpResponse httpResponse = http.send(httpRequest);

I feel you can simplify things using the permission set. You can give community access using permission sets.

And the best thing is we can assign permission sets using apex. Thus simplifying your work would be just assigning PS to the select user in apex.

 PermissionSetAssignment psa = new PermissionSetAssignment
    (PermissionSetId = communityAccessPS, AssigneeId = userId);
    insert psa;
