You can make changes to externally linked data that is pulled in via the Connect API without having my data overwritten by the source providers. Because data from source systems like EHRs and wearable devices is synced every 5 minutes or less, any updates made by your app may be overwritten by the background sync from 1upHealth. To modify or save changes to data from source systems, it’s necessary to create a new unique resource and change the data in that. The new resource you create will not be linked to the backend data sync. If there are multiple provider systems, your application logic can use data from multiple systems and apply changes to the new unique resource.
