DrChrono is a cloud EHR and practice management platform used by many independent practices, and its public API has made it a common integration target for digital health vendors. The API is well documented, but scopes, user permissions, token lifetimes and partner approval all shape what you can build and how quickly. This guide explains how DrChrono’s API works in practice and how to deliver integrations that hold up in production. For broader EHR connectivity, see our EHR and EMR integration services.

How the DrChrono API Works
DrChrono offers a versioned REST API using OAuth 2.0, alongside FHIR endpoints for regulatory interoperability. The REST API is the main path for practice workflows, covering patients, appointments, clinical documents, billing and more. Understanding its authorization model is the key to building reliable integrations.
OAuth 2.0 authorization flow
DrChrono uses the OAuth 2.0 authorization code flow. Your app redirects users to DrChrono to approve access, then exchanges the returned code for access and refresh tokens. Applications are created on DrChrono’s API management page, where client credentials and redirect URIs are configured.
Scopes and user permissions together
Access depends on two layers. Scopes are granted during the OAuth process, while user permissions are set inside the DrChrono web app. An app can only reach data when both are in place, so missing permissions often explain unexpected authorization errors during testing.
Token lifetimes and refresh
DrChrono’s documentation states access tokens last 48 hours. Applications must use refresh tokens to obtain new access tokens before expiry. Build token refresh into background processes carefully, because failed refreshes silently stop data syncs until a user reconnects the application.
API versioning
The DrChrono API is versioned, with versions labeled active, deprecated or unsupported. Requests can specify a version through a dedicated header. Track version status, because unsupported versions may be deactivated, and plan migrations well before deprecated versions stop working. Test new versions before switching.
What You Can Build With DrChrono
DrChrono’s REST API covers a broad range of practice data, making it suitable for many vendor products. The use cases below represent the most common integrations, with notes on how each fits DrChrono’s API capabilities and practice workflows.
Scheduling and patient engagement
Reminder, intake and engagement vendors use appointment and patient endpoints to sync schedules and patient details. Combining scheduled syncs with careful change detection keeps data current. Respect rate limits by requesting only needed data and avoiding unnecessary repeated calls. Webhooks can reduce polling where available.
Clinical documents and data
Vendors can read and write clinical documents and related data, supporting workflows such as uploading reports or retrieving notes. Validate document formats and patient matching carefully, because errors in clinical records directly affect patient care and practice trust. Test every document type you plan to support.
Billing and revenue cycle tools
Billing and analytics tools use DrChrono’s billing-related endpoints, which require specific user permissions. Confirm the exact permissions your integration needs, and include them in onboarding instructions so practice administrators configure accounts correctly before connecting your application. Reconcile synced data with practice staff during pilots.
Apps embedded in the patient view
DrChrono’s tutorial notes that API apps can be incorporated into the patient information page through an iframe. This lets vendors present tools alongside the patient record, improving workflow fit without requiring users to switch applications constantly. Test embedded layouts on common screen sizes.
FHIR and Patient Access
Beyond the REST API, DrChrono provides FHIR endpoints aligned with regulatory requirements. These serve different purposes from the REST API, and understanding the distinction prevents vendors from building on the wrong interface for their product’s needs.
SMART on FHIR endpoints
DrChrono offers SMART on FHIR R4 endpoints, supporting standardized access aligned with federal interoperability rules. These suit patient-facing apps and standards-based integrations. Our SMART on FHIR app development team builds apps that use these endpoints effectively. Confirm which resources each endpoint supports today.
When to use FHIR versus REST
Use FHIR when your product needs standardized, portable data access across many EHRs, especially for patient access. Use the REST API for operational workflows such as scheduling, billing and document management, where DrChrono’s proprietary endpoints offer broader coverage. Document the choice for each feature.
Combining both approaches
Many products combine FHIR for standardized clinical reads with REST for operational tasks. This balances portability and functionality. Our FHIR and HL7 integration services help vendors design hybrid integrations that stay maintainable as products expand. Map identifiers carefully between the two interfaces to avoid duplicates.
Documentation across sources
Developers report that DrChrono documentation spans several locations, including legacy API documentation and separate FHIR resources. Bookmark the current references you rely on, confirm which version each describes and keep internal notes so your team stays aligned. Review references whenever versions change.
Access and Partner Requirements
Technical documentation is public, but production access and marketplace distribution involve DrChrono directly. Planning these steps early helps vendors align launch dates with realistic approval timelines and avoid surprises once pilot practices are ready.
Creating your application
Developers create applications through DrChrono’s API management page, configuring redirect URIs and receiving client credentials. Use separate applications or credentials for testing and production where possible, and store secrets securely outside source code and client-side applications. Limit who can view production secrets internally.
Production and partner access
Production and partner access is not fully self-serve. Third-party reviews note that it begins by contacting DrChrono’s API team, with partner approval required for marketplace distribution. Contact DrChrono early to understand current requirements for your product type. Prepare product and security documentation beforehand.
Rate limits
DrChrono applies rate limits to API usage, and its documentation directs developers to contact the API team or account representatives for increased limits. Design efficient integrations from the start, and request higher limits before scaling to many practices. Monitor usage as practices grow.
Practice authorization
Each practice must authorize your application through OAuth and grant users appropriate permissions. Provide clear onboarding guides explaining required permissions. Simple, accurate instructions reduce support tickets and help practices activate your integration successfully on the first attempt. Include screenshots in your setup guides where possible.
Building a Reliable DrChrono Integration
The steps below reflect how we deliver DrChrono integrations. They focus on authorization, token management and practice onboarding, which cause most production issues, alongside the core development work that delivers your product’s features.
Step 1: Map requirements to endpoints
List every data element and action your product needs, then map each to REST or FHIR endpoints with required scopes and permissions. Identify gaps early, and discuss them with DrChrono before committing to features that depend on unavailable capabilities. Record every mapping decision clearly.
Step 2: Implement OAuth and token handling
Build the authorization flow, secure token storage and automatic refresh. Handle revoked access and expired refresh tokens gracefully, alerting users to reconnect. Robust token handling prevents silent sync failures that frustrate practices and damage trust in your product. Monitor refresh failures continuously.
Step 3: Build and test features
Develop features using test accounts and realistic data scenarios. Handle pagination, missing fields and permission errors explicitly. Log requests during development to diagnose issues quickly, and remove sensitive data from logs before moving into production environments. Document expected behavior for each scenario tested.
Step 4: Pilot with practices
Launch with pilot practices, monitor sync accuracy, error rates and performance, and gather user feedback. Pilots reveal permission setups, workflow differences and data quirks that test accounts rarely show. Fix issues quickly before broader rollout. Agree on success measures with each pilot practice first.
Step 5: Scale and maintain
Document onboarding, monitor API usage against rate limits and track version changes. Assign ownership for responding to DrChrono updates. Ongoing maintenance keeps integrations stable as both your product and DrChrono’s platform continue to evolve. Review integration health metrics regularly with your product and support teams.
