Developer documentation

Welcome to the Patients Know Best developer page. At PKB we have two principles: first, the patient owns the data, and second, we will provide the data to anyone the patient wants. So we built the PKB API so that other developers can build software that helps patients using the data in PKB accounts.

If you have questions about using the API, or would like to set up a call to discuss integration, do email us on

Also, if you find a bug or think our service isn't working as expected, you can raise a helpdesk ticket by emailing

We are always updating our developer APIs with more features; subscribe to our developer blog so we can keep you posted!
