API Development on Subscription List (Marketing List Entity & List Members)

(0) ShareShare
ReportReport
Posted on by 55

Hi folks, 

hoping to get some Dev assistance or a contact in the right direction. Our Dynamics 365 Marketing Client (external website) wants members to update their marketing preferences behind their gated login. As you know, the embedded Subscription Centre form won't load unless you've previously submitted a form or land on the form via an Email. 

The client has requested to instead surface the available subscription lists (marketing list entity) via API which we're building (using .NET). So far we can successfully remove the member from a subscription list, however appending a member to a list is proving to be more challenging. 

Does anyone know of a Microsoft Dev engineer we can reach out to or has anyone attempted this before? 

Thank you!

    Hello, 

    I've reached out to the dev team and below is a code snippet on how to add contacts to the list:

    var addListMembersListRequest = new AddListMembersListRequest
                        {
                            MemberIds = new[] { contactId },
                            ListId = listId
                        };
    
                        service.Execute(addListMembersListRequest);
