Overview
Fasten Connect provides a curated list of sandbox portal logins so you can authenticate against major EHRs as a test patient. These credentials only work while your integration is running intest mode. They are ideal for logging into Epic, Cerner, AthenaHealth, and other health systems to validate OAuth flows,
tune UI messaging, and ensure Fasten Stitch renders the right prompts at each stage of the connection.
Credential catalog
Each sandbox account mimics a patient record inside its respective vendor portal. Because they are controlled environments, you might notice limited or unrealistic data. Use the table below to pick the health system, log in as the provided test patient, and walk through the consent process end-to-end.Fastenβs official test server is FooClinic, which includes multiple synthetic patient personas for richer end-to-end testing. See the Official FooClinic Test Data section for available patients, credentials, resource counts, and persona summaries.
Data expectations & testing strategy
- Sandbox accounts vary widely in both the quantity and quality of data they expose. Some include full longitudinal histories while others only show a handful of labs or medications.
- For UI testing or machine learning exercises, we strongly reccommend that you use the richer synthetic resources outlined in the Test Data guide.
