Thanks for reaching out Jeanne, and for the kind words about our calendar systems!
There is no built-in (or “out-of-the-box”) support for the “Wild Apricot” system you mention, so building integration between these systems would unfortunately require extensive custom coding. 🙁
To implement the custom coding, you would have to write that custom code or hire a professional developer to do it for you. We have a list of great developers here → http://m.tri.be/18k1 (and have no affiliation with any of these folks—they’re simply some well-respected names in the community that we’ve compiled to share in situations like this one).
Sorry to disappoint! Please let me know if there are any other issues or questions I can try to help with.
Sincerely,
George
