Application Programming Interface

Application Programming Interface (API) is a technology that allows our electronic health records (EHRs) to communicate with outside applications. Using API, you may request your health information through an app of your choice as long as that app utilizes FHIR industry standards and meets the specifications of our EHRs.

In order to keep your data safe, you must confirm your identity before CHRISTUS releases any of your health information to an outside app. Your identity is confirmed using your Patient Portal username and password. If you are not already enrolled in your CHRISTUS Patient Portal, please refer to our patient portal page.

CHRISTUS is not responsible for the Terms of Service of any app you may select and does not endorse any specific app for use. However, apps that we have worked with in testing API functionality are listed below:

  • 1UpHealth

For any questions about an app, please first contact the app developers. If your app of choice has confirmed that they meet FHIR industry standards but is not appropriately receiving your CHRISTUS Health information, please contact our support team at 855-344-0442.
