ModMed

ModMed provides strong write access through its proprietary FHIR API after a partner onboarding process. The dual-track API architecture (proprietary vs. certified) means maintaining two integration paths with different auth methods.

Integration considerations

  • Two separate API tracks with different auth methods — developers must maintain dual integration paths
  • Proprietary API uses OAuth2 Password Grant (deprecated in OAuth 2.1 draft)
  • No webhooks — must poll for data changes using _lastUpdated parameter
  • Per-practice credential management — each practice generates separate credentials per vendor
  • Proficiency demo required before production access adds onboarding time
  • Proprietary API does not support ModMed GI/gGastro practices

Need help with gated access?

Some capabilities require contracts, partner agreements, or special approval. Cobalt has existing integrations with these systems.
