Microsoft Graph

Microsoft Graph API Orchestration Skill

Microsoft Graph is a unified REST API endpoint for accessing Microsoft Cloud resources across Microsoft 365, Windows, and Enterprise Mobility + Security. Base URL: https://graph.microsoft.com/{version}/{resource}

API Versions: v1.0 (production) or beta (preview) Authentication: OAuth 2.0 via Azure AD Data Format: JSON

When to Load Which Resource

Orchestration Protocol

Phase 1: Analyze Your Task

Identify which service area you need by answering:

• What resource? (users, files, messages, events, etc.)
• What action? (read, create, update, delete)
• Who? (signed-in user or service account)
• Permissions? (delegated or application)

Phase 2: Load the Right Resource

Use the decision table above to find your resource file. Each resource includes:

• Complete endpoint reference with base paths
• Request/response examples for all CRUD operations
• Query parameters and filter options
• Required permissions (delegated and application)
• Error handling patterns and best practices
• Common workflows and patterns

Phase 3: Implement with Confidence

Each resource shows practical, copy-paste-ready examples for your use case.

Universal Graph Concepts

Standard Query Parameters:

$select=prop1,prop2              Choose properties to return
$filter=startsWith(name,'A')     Filter results by condition
$orderby=name desc               Sort results (asc or desc)
$top=25                          Limit to 25 results (default 20)
$skip=50                         Skip first 50 results
$expand=members                  Include related/nested data
$count=true                      Include total count in response
$search="keyword"                Full-text search across content

Standard CRUD Operations:

GET /me/messages?$select=subject&$top=10        # Read
POST /me/events {"subject": "Meeting", ...}     # Create
PATCH /users/{id} {"jobTitle": "Manager"}       # Update
DELETE /me/messages/{id}                        # Delete

Pagination: Always follow @odata.nextLink in responses for complete data sets

Batch Requests: Use POST /$batch to combine 1-20 operations into single call

Delta Queries: Use GET /users/delta to track changes since last query via @odata.deltaLink

Error Response Format:

{"error": {"code": "Code", "message": "Description"}}

Common Status Codes:

• 200/201/204: Success
• 400: Invalid request
• 401: Authentication required
• 403: Insufficient permissions
• 404: Resource not found
• 429: Rate limited (check Retry-After header)
• 500-503: Server error (implement exponential backoff)

Resource File Index

Best Practices

Performance: Use $select for specific properties, implement pagination, cache tokens, use batch for bulk ops, apply delta queries for sync scenarios

Security: Store tokens securely (never in code), request least-privilege permissions, use managed identities for Azure, rotate credentials every 90 days, validate all responses

Development: Test in beta endpoint first, monitor deprecation notices, implement exponential backoff for retries, respect rate limiting, check Graph health status

Troubleshooting:

• 401 Unauthorized → Check token validity and scopes
• 403 Forbidden → Verify permissions are configured in Azure AD
• 404 Not Found → Verify resource ID and that resource exists
• 429 Too Many Requests → Implement retry with exponential backoff

---

Consolidation Strategy

Service Domain Mapping

1. Applications & Authentication

Consolidated from: applications.md + identity.md (auth sections) + security.md (auth methods)

• Rationale: All authentication-related operations require understanding app registration, credentials, and OAuth flows
• New Size: 668 lines (focused content, no redundancy)
• Key Sections: App registration, service principals, OAuth2, credentials, authentication methods, federation
• Coverage: 100% preservation, reorganized for auth workflow

2. Mail & Calendar

Consolidated from: mail.md + calendar.md

• Rationale: Email and calendar operations are tightly integrated in Microsoft Graph (same mailbox concept)
• Original Size: 350 + 300 = 650 lines separately
• New Size: 1,190 lines (combined with full detail)
• Key Sections: Email operations, attachments, mail rules, calendar events, meetings, free/busy
• Coverage: 100% preservation, enhanced with cross-operation patterns

3. Planning & Tasks

Consolidated from: planner.md + todo.md + onenote.md

• Original Size: 398 + 365 + 384 = 1,147 lines separately
• New Size: 931 lines (35% reduction by removing header redundancy)
• Rationale: All three services handle task/item management; can be used complementarily
• Key Sections: Planner (team tasks), To Do (personal tasks), OneNote (notes), comparison table, combined patterns
• Coverage: 100% preservation, intelligently consolidated

4. Files & OneDrive (Renamed)

From: files.md → files-onedrive.md

• Size: 705 lines (already comprehensive, no consolidation needed)
• Rationale: File operations span OneDrive, SharePoint, and Teams; clear naming improves discovery
• Coverage: No changes to content, only renamed for clarity

5. Teams & Communications (Renamed)

From: teams.md → teams-communications.md

• Size: 681 lines (already comprehensive, no consolidation needed)
• Rationale: Teams is part of broader communications picture; improved naming for discoverability
• Coverage: No changes to content, only renamed for clarity

6. Users & Groups

From: users-groups.md → users-groups.md

• Size: 612 lines (already properly organized)
• Rationale: Already focused and well-organized; no consolidation needed
• Coverage: No changes

7. Security & Governance

Consolidated from: security.md + identity.md + devices.md + education.md + reports.md

• Rationale: All governance/compliance/security operations; identity protection connects to conditional access
• New Size: 903 lines (thoughtful consolidation of 5 sources)
• Key Sections: Security alerts, threat hunting, risk detection, conditional access, device management, compliance, education, reporting
• Coverage: 100% preservation, organized by governance workflow

Orchestration Hub Design

Decision Table (8 Use Cases → 7 Service Areas)

| I Need to... | Service Area | Load Resource |
|---|---|---|
| Manage users, groups, directory | Identity & Access | users-groups.md |
| Setup auth, tokens, app registration | Applications & Auth | applications-auth.md |
| Handle emails, rules, folders | Mail & Calendar | mail-calendar.md |
| Schedule events, meetings | Mail & Calendar | mail-calendar.md |
| Upload files, sync, share | Files & OneDrive | files-onedrive.md |
| Create teams, channels, messages | Teams & Chat | teams-communications.md |
| Manage plans, tasks, to-do lists | Planning & Tasks | planning-tasks.md |
| Security alerts, compliance, devices | Security & Governance | security-governance.md |

Design Rationale:

• 8 common user tasks → mapped to 7 service areas (2 tasks use same resource)
• Clear decision path: "I need to..." → Identifies service area → Points to specific resource
• Cross-references bidirectional: Hub → Resources → Hub patterns

Orchestration Protocol (4-Phase)

1. Analyze Your Task: Identify resource, action, permission model 2. Load the Right Resource: Use decision table to find focused reference 3. Implement with Confidence: Each resource has endpoint examples, permissions, patterns 4. Handle Common Patterns: Universal concepts in hub (pagination, errors, batch, delta)

---

Key Implementation Details

Progressive Disclosure Pattern

• Hub (342 lines): Navigation, overview, orchestration protocol, universal concepts
• Resources (5,690 lines): Complete technical reference, detailed endpoints, examples
• User Journey: Find what I need → Load right resource → Implement → Use patterns

Content Organization

Each consolidated resource follows consistent structure: 1. Overview: Purpose and service area description 2. Base Endpoints: Base URLs and API versions 3. Operations: Organized by entity (GET, POST, PATCH, DELETE) 4. Query Parameters: Filtering, sorting, pagination options 5. Permissions: Required delegated and application permissions 6. Common Patterns: Real-world workflows 7. Best Practices: Performance and security guidance

Cross-References

• Hub decision table links to all 7 resources with relative paths
• Service area overviews reference their resource file
• Universal concepts reference relevant resources
• Resource files reference hub for orchestration protocol

---

Consolidation Rationale

Mail + Calendar Consolidation

Justification: In Microsoft Graph, mail and calendar are unified under the mailbox concept:

• Same user endpoint (/me)
• Calendar events integrated with mail
• Meeting requests flow through both
• Attendee management spans both
• Single permission scope covers both operations
• Users typically work with both together

Result: 1,190 line consolidated resource vs scattered reference

Planning + To Do + OneNote Consolidation

Justification: Three complementary task/note management services:

• Planner: Team-based task planning
• To Do: Personal task management
• OneNote: Note-taking and reference
• Common pattern: Use Planner for team work, To Do for personal, OneNote for reference
• Decision matrix shows when to use each
• Often used in combination

Result: 931 line consolidated resource (35% reduction from 1,147 lines) without content loss

Security Consolidation (5 Files)

Justification: All governance/compliance operations interconnected:

• Alerts trigger investigations (security.md)
• Risk detection informs conditional access (identity.md)
• Device compliance enforces policy (devices.md)
• Education APIs use same governance patterns (education.md)
• Reports measure governance effectiveness (reports.md)
• Single workflow: Detect → Assess → Policy → Measure

Result: 903 line consolidated resource covering all governance domains

Files-OneDrive Rename

Justification: Clarity improvement

• Service is fundamentally about file operations in OneDrive/SharePoint
• Current name "files.md" ambiguous without context
• Renamed to "files-onedrive.md" for immediate clarity
• No content changes

Teams-Communications Rename

Justification: Consistency with other service area names

• Teams service now scopes communications clearly
• Renamed from "teams.md" to "teams-communications.md"
• Aligns with "users-groups", "mail-calendar" naming pattern
• No content changes

---

Benefits of New Structure

For Users

1. Faster Navigation: Decision table shows exactly which resource to load 2. Better Discovery: Service area names match user mental models 3. Progressive Disclosure: Hub for overview, resources for detail 4. Reduced Cognitive Load: Don't need to know all 14 files to start

For Maintainers

1. Easier Updates: Consolidated files reduce places to update same content 2. Consistency: All resources follow same structure 3. Clear Ownership: Each service area has one authoritative file 4. Better Merge Resolution: Fewer scattered files = fewer conflicts

For Integration

1. Focused References: Related operations grouped together 2. Complete Coverage: All 7 service areas included 3. Example Patterns: Common workflows documented 4. Permission Reference: Clear permission requirements per operation

Best Practices

1. Use managed identities when possible (Azure resources) 2. Rotate secrets regularly (every 90 days recommended) 3. Use certificates instead of secrets for production 4. Use federated identities for CI/CD (no secrets) 5. Request least privilege permissions 6. Use workload identity federation for external systems 7. Monitor consent grants regularly 8. Document custom app roles clearly 9. Implement proper token caching 10. Test multi-tenant apps in multiple tenants

Applications & Authentication - Microsoft Graph API

This resource covers app registrations, service principals, OAuth2 permissions, authentication methods, and credentials management in Azure AD.

Base Endpoints

• Applications: https://graph.microsoft.com/v1.0/applications
• Service Principals: https://graph.microsoft.com/v1.0/servicePrincipals
• OAuth2 Permissions: https://graph.microsoft.com/v1.0/oauth2PermissionGrants
• Authentication Methods: https://graph.microsoft.com/v1.0/users/{id}/authentication

Overview

Authentication in Microsoft Graph follows OAuth 2.0 standards: 1. App registers in Azure AD 2. User grants permissions (delegated) or app gets permissions (application) 3. Access token obtained 4. Token used in API calls

Best Practices

Email: 1. Use $select to get only needed properties 2. Implement pagination for large message sets 3. Use delta queries for mail sync 4. Batch operations when updating multiple messages 5. Handle large attachments with upload sessions

Calendar: 1. Use calendarView instead of filtering for date ranges 2. Specify time zones explicitly 3. Handle recurring events properly 4. Use findMeetingTimes for complex scheduling 5. Respect working hours when scheduling

Combined: 1. Cache folder IDs to avoid repeated lookups 2. Respect rate limits (implement retry logic) 3. Handle encoding properly for attachment content 4. Use well-known folder names when possible 5. Monitor Retry-After header on 429 responses

Best Practices

1. Use upload sessions for files > 4 MB 2. Implement delta queries for sync scenarios 3. Handle conflicts appropriately (rename, replace, fail) 4. Cache thumbnails instead of regenerating 5. Use batch requests for multiple operations 6. Respect rate limits - implement retry logic 7. Validate file types before upload 8. Use @microsoft.graph.downloadUrl for downloads 9. Monitor async operations (copy, large uploads) 10. Handle quota limits - check before upload

---

Rate Limits

• Typical limit: Variable based on file size and operation
• Large uploads: Use upload sessions
• Monitor Retry-After header on 429 responses
• Batch operations have separate limits

---

Error Handling

Common errors:

• itemNotFound - Item doesn't exist
• resourceModified - Item changed (use etag)
• unauthenticated - Authentication required
• accessDenied - Insufficient permissions
• quotaLimitReached - Storage quota exceeded
• nameAlreadyExists - Name conflict

Best Practices

Email: 1. Use $select to get only needed properties 2. Implement pagination for large message sets 3. Use delta queries for mail sync 4. Batch operations when updating multiple messages 5. Handle large attachments with upload sessions

Calendar: 1. Use calendarView instead of filtering for date ranges 2. Specify time zones explicitly 3. Handle recurring events properly 4. Use findMeetingTimes for complex scheduling 5. Respect working hours when scheduling

Combined: 1. Cache folder IDs to avoid repeated lookups 2. Respect rate limits (implement retry logic) 3. Handle encoding properly for attachment content 4. Use well-known folder names when possible 5. Monitor Retry-After header on 429 responses

Common Patterns

Create Team with Channels

# 1. Create team
POST /teams
{...}

# 2. Create channels
POST /teams/{team-id}/channels
{...}

Post Announcement to Multiple Channels

Use batch requests:

POST /$batch
{
  "requests": [
    {"id": "1", "method": "POST", "url": "/teams/{id}/channels/{ch1}/messages", "body": {...}},
    {"id": "2", "method": "POST", "url": "/teams/{id}/channels/{ch2}/messages", "body": {...}}
  ]
}

Monitor Team Activity

# Subscribe to change notifications
POST /subscriptions
{
  "changeType": "created,updated",
  "notificationUrl": "https://webhook.site/...",
  "resource": "/teams/{team-id}/channels/{channel-id}/messages",
  "expirationDateTime": "2024-01-20T00:00:00Z"
}

---

Best Practices

1. Use resource-specific consent (RSC) for Teams apps 2. Respect rate limits - especially for message sending 3. Handle throttling - implement exponential backoff 4. Use webhooks for real-time updates (change notifications) 5. Batch operations when possible 6. Cache team/channel metadata 7. Validate permissions before operations 8. Use delta queries for message sync 9. Handle deleted content appropriately 10. Test with private channels (different permission model)

---

Rate Limits

• Channel messages: Varies by operation
• Chat messages: Throttled per user
• Team creation: Limited to prevent abuse
• Monitor Retry-After header
