name: Veradigm FHIR API Rate Limits
description: Veradigm does not publish explicit numerical rate limits for the FHIR R4 API in public documentation. Access is gated by OAuth 2.0 token lifecycle and plan tier. Rate limit policies are typically communicated during the integration certification process. Sandbox and production environments may have different constraints.
