Important Concepts

Before integrating with Metric Health's SDK, it's important to understand some key concepts.

API key

When you register your app with Metric Health, you will receive a unique API key that is associated with your account. This API key is required to authenticate your requests to our server.


A user UUID (Universally Unique Identifier) is a unique identifier that is associated with each user who has authorized your app to access their health data. We use this UUID to anonymize the user's data and to send it to your server.

It's important to note that we don't request or store any personal information about the user. Instead, we map all of their health data to this UUID and send it to your server. This ensures that the data is fully anonymized, and you are the only one who knows which user the data is associated with.

We recommend using the UUID or ID you are already using for your user model in your app to make it easier to map the user's health data to their account in your app.

By understanding these concepts, you will be better equipped to integrate with our SDK and make the most of the health data that we provide.
