I was looking at your product. We're currently using WordPress and Campaign Monitor. We have premium subscribers that pay each month for access to the blog. These users get put into a "Gold Member" WordPress user group and then need to be put on a special Campaign Monitor mailing list. We're looking for something that will automate the process of adding a new user that signs up for the premium service and also delete them if they fail to pay us or decide to cancel. Here's how it would work:
1. Customer goes to our website and goes through check out system
2. Our API adds their username and password to WordPress and upgrades them to "Gold Member" automatically
3. This member then gets added to the "Gold Member" mailing list in Campaign Monitor.
4. If the user cancels or we fail to get their payment, our API downgrades them from Gold Member and they should be removed from the mailing list.
