The Create Contact (Async) API allows you to create contacts in the system without waiting for each contact to be processed immediately. It supports adding multiple contacts, defining attributes, and assigning them to audience lists pr groups. Since this API works asynchronously, it prrocesses the data in the background after accepting the request. The response only confirms that the request has been received successfully- it does not indicate that contact creation is complete.
