SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Integrating Microsoft Graph correctly is error-prone: choosing the wrong authentication flow, missing pagination, ignoring throttling, or over-scoping permissions leads to broken or insecure integrations. This Skill guides developers through correct Graph SDK setup and usage patterns across .NET, TypeScript/JavaScript, and Python.

Core Features & Use Cases

  • Language-specific workflows: Detects the project language and loads dedicated references for .NET, TypeScript/JavaScript, or Python with correct packages, client setup, and code patterns.
  • Authentication decision tree: Maps scenarios (daemon, OBO, managed identity, CLI, SPA) to the correct auth flow and credential type.
  • Advanced Graph patterns: Covers batching, delta queries, change notifications, pagination with PageIterator, and 429 throttling handling.
  • Use Case: A developer building a background service that syncs user mailboxes can follow the client credentials setup, implement delta queries for incremental sync, and enable retry middleware — all with least-privilege permissions.

Quick Start

Ask the assistant to integrate Microsoft Graph into your project to read the signed-in user's messages, and it will detect your language and produce the correct SDK setup and code.

Frequently Asked Questions about msgraph-sdk

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I authenticate with Microsoft Graph SDK?▼

Choose the flow based on your scenario: client credentials for daemons, On-Behalf-Of for APIs acting as a signed-in user, managed identity for Azure-hosted apps, and device code or interactive browser for CLI tools. Pass the matching Azure Identity credential to GraphServiceClient.

How do I handle pagination in Microsoft Graph API responses?▼

Graph paginates collections and returns an @odata.nextLink when more pages exist. Use the SDK's PageIterator helper, available in the .NET, TypeScript, and Python SDKs, to walk all pages automatically instead of assuming a single response.

Which Microsoft Graph SDK should I use for Python?▼

Install the msgraph-sdk package together with azure-identity. The Python SDK is async-first, so use the azure.identity.aio credential variants and run calls inside an asyncio context or an async framework like FastAPI.

Why does Microsoft Graph return HTTP 429 throttling errors?▼

Graph throttles aggressive request patterns and returns 429 with a Retry-After header specifying exact wait seconds. Enable the SDK's built-in retry middleware and avoid large parallel fan-outs; use batching or queuing instead of fixed backoff.

What is the difference between application and delegated Graph permissions?▼

Application permissions run without a signed-in user and suit daemons, requiring admin consent. Delegated permissions run in a signed-in user's context. Always request the minimum scopes needed and verify requirements in the Graph permissions reference.

How do I sync Microsoft 365 data changes incrementally?▼

Use delta queries: the first call to an endpoint like /users/delta returns all items plus a deltaLink, and subsequent calls with that link return only changes. Store the deltaLink durably between sync runs.
