CNCBI Open Application Programming Interface (Open API)

  • You are advised to be aware of any third party service providers’ requests to acquire or collect your personal data, for example, your contact information or other account information. You should always consider the purpose and scope of data collection as well as the associated risks before granting consents to the third party service providers to avoid related risks, such as data leakage or being stolen.
  • You are advised to be vigilant to bogus calls or other similar scams. There will be notification to you or the public whenever CNCBI or the partnering TSP becomes aware of such scams. Whenever you are in doubt about a call, an email or other message; you may first authenticate the identity of the callers or senders who purport to be CNCBI’s representatives using CNCBI’s dedicated hotlines which can be found by clicking here or at the HKMA’s website.
