The DataMotion Direct messaging API facilitates all message handling with various methods for sending, receiving, and manipulating a user's Direct Messaging inbox.

All functions within this API require a Session Key retrieved from the Get A Session Key function. This function should always be performed first, then the Session Key response should be used in an X-Session-Key header for all other API requests.

This API can only be used on DataMotion's HISP platform https://ssl.dmhisp.com and its accompanying sandbox environment https://sandbox.dmhisp.com
