What is SimplePractice?

SimplePractice is a cloud EHR and practice management platform focused on solo and group practices in behavioral health and related outpatient care. Core capabilities typically include:

  • Scheduling and calendar management (office, telehealth, group sessions)
  • Client portal with online booking, messaging, and document sharing
  • Paperless intake forms, e-signatures, and consent management
  • Telehealth by SimplePractice with HIPAA-compliant video
  • Clinical documentation (progress notes, treatment plans, diagnoses)
  • Insurance billing (837P) and remittance (835) reconciliation
  • Payment processing and card-on-file for private pay
  • Basic reporting across caseload, financials, and productivity
  • Team management, roles/permissions, audit trails

Common data entities:

  • Clients (demographics, contacts, portal status, insurance)
  • Clinicians/Staff (roles, NPI, taxonomy, locations)
  • Appointments/Sessions (service codes, status, telehealth links)
  • Services (CPT codes, fee schedules, POS, modifiers)
  • Insurance Policies (payer, member ID, plan, copay)
  • Claims (837P lines, payer, status, adjudication)
  • Remittances/ERAs (835 summaries, payment posting)
  • Payments, Invoices, and Superbills
  • Clinical Notes and Treatment Plans (templates, signatures, locks)
  • Intake Forms and Documents (consents, questionnaires, attachments)

The SimplePractice Integration Challenge

Practices rely on SimplePractice daily, but turning portal-based workflows into automated pipelines can be hard:

  • Limited public API: Historically, customers have requested a formal API and webhooks for appointments, intakes, payments, and documentation events
  • Portal-first design: Key scheduling, intake, and documentation steps live in web UIs and batch exports rather than unified, documented endpoints
  • Strong security controls: MFA/2FA and session protections complicate headless automation and long-lived integrations
  • Clinical note constraints: Note locking, signatures, and audit trails must be preserved; edits may be restricted post-lock to stay compliant
  • Calendar and telehealth nuances: Two-way calendar sync and ephemeral telehealth links require careful session handling
  • Billing pipelines: Claim submission windows, payer-specific rules, and batch ERA retrieval introduce timing and formatting complexity

How Supergood Creates SimplePractice APIs

Supergood reverse-engineers authenticated browser flows, batch interfaces, and network interactions to deliver a resilient API endpoint layer for SimplePractice.

  • Handles username/password and MFA (SMS, email, TOTP) securely
  • Maintains session continuity with automated refresh and change detection
  • Normalizes client, appointment, intake, note, and claim objects for consistent integration
  • Aligns with your entitlements and licensing to ensure compliant access
  • Bridges exports/attachments where applicable with signed URL retrieval and delivery

Frequently asked questions

Supergood supports workflows across commonly used SimplePractice areas, subject to your entitlements: clients, scheduling/telehealth, intake/document retrieval, clinical note metadata, payments, and insurance claims. Exact coverage is finalized during integration assessment.

We handle username/password + MFA (SMS, email, TOTP). For documents, we generate signed URLs, respect expiration windows, and preserve audit and signature context.

Where your permissions allow, we can create progress notes tied to appointments and apply locks/signatures consistent with audit requirements. Some organizations prefer read-only metadata access to notes; we support both patterns depending on policy.

Yes. We can orchestrate two-way calendar syncs and accounting flows while using SimplePractice as the clinical source of truth, pushing financial summaries to tools like QuickBooks/Xero and syncing availability with Google Calendar where permitted.
