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

🚧
The HPD is designed to be an address list of real healthcare providers and if you are using this API on the sandbox environment you will not retrieve any real results.
