OpenEvidence Webhooks & Events
Overview
OpenEvidence delivers webhook notifications for clinical evidence retrieval workflows. Subscribe to events when queries complete, evidence bases are updated, new citations are added, or clinical reviews are flagged. Use these webhooks to keep clinical decision support systems current and trigger downstream audit workflows in real time.
