All access to the MLS IDX API requires authentication using digest authentication (RFC 2617, HTTP Authentication).

All transactions can be performed by clients using either HTTPS GET or HTTPS POST methods. Security Requirements:

Data collection, synchronization, and distribution through the MLS IDX API occur through centralized processes that run during the early hours of each day. To ensure you are receiving the most accurate and up-to-date listing information, and to avoid possible inconsistencies, it is recommended that clients begin pulling data from MLS IDX API feeds after 10:00 AM.
