Some data providers don't provide data through a web API, and restrict data access to on-device apps.
See Integrations for a full list of sdk-based integrations.
This means that users cannot agree to share through the widget. Instead, the user has to agree to share data for e.g. Apple Health or Samsung Health on their device directly.
This requires your product to call the corresponding on-device SDK for the data provider (e.g. calling Apple Health and ask for data sharing).
The SDKs offer two separate functionalities:
Fetch data from providers who restrict access to on-device apps
Make calls to the Terra web API
Upon successful authentication through completion of a widget session, you will receive the Terra userID and the provider in the customisable redirect URL (this can be a deep link). For on-device data access, you will only receive the provider (and a NULL userID), and will have to trigger the corresponding SDK for the provider on the user device to complete the authentication.
For example, for the Apple SDK:
- Your application opens a widget session for the user
- The user selects Apple as a provider
- Upon completion, you will receive
- You make my application call the Terra Apple SDK
- The user gets asked by Apple Health to allow data sharing with Terra
- Each SDK provides native support as well as framework support (e.g. React Native) where possible
