Credentials & Certificates
Overview
Credentials & Certificates covers the issuance, display, and verification of course completion certificates and program credentials. When a learner completes a course (meeting grade thresholds), the platform generates a certificate; completing a program of courses generates a program credential.
The `credentials` service is a standalone Django microservice extracted from `edx-platform` to handle certificate generation, storage, and verification. Certificates are publicly shareable and verifiable via URL.
Current State (2026)
• Certificate generation: Triggered by grade thresholds; generated as signed HTML pages (not PDFs) with unique shareable URLs
• Program credentials: Issued by the `credentials` service when all program courses are completed
• Learner record: `frontend-app-learner-record` MFE shows all earned credentials and allows sharing
• Themes: `credentials-themes` provides customizable certificate templates per organization
• Verification: Public certificate URLs are verifiable; certificates contain learner name, course, date, grade
• Legacy PDF: Historical PDF certificate generation deprecated in favor of HTML certificates
Architecture
• `credentials` service: Standalone Django app; receives signals from `edx-platform` when courses are completed; manages credential issuance and sharing
• `edx-platform` integration: LMS sends completion/grade signals; `credentials` listens and issues certificates
• Certificate rendering: HTML templates rendered server-side with learner data; not PDF (PDF generation was dropped)
• Sharing: Each certificate has a unique URL; learner can share on LinkedIn, email, etc.
• Program logic: Program completion tracked by `credentials`; checks all required course certificates
History
Origin
• Year introduced: ~2013 (certificates launched early in edX history)
• Initial implementation: Certificates generated directly in `edx-platform`; PDF rendered via background Celery task
• Context: Certificates were a key value proposition for MOOCs — social proof of completion that learners could share with employers
Key Milestones
