Reducing Network Latency in Microsoft 365 Integrations with Graph API Batching
Reduce network overhead and latency in Microsoft 365 integrations by using the Graph API /$batch endpoint to combine up to 20 requests into a single HTTP call.
Reducing Microsoft Graph API Noise with ETag-Based Conditional Requests
Stop over-fetching OneDrive data. Learn how to use ETag-based conditional requests in Microsoft Graph to reduce API noise, avoid 429 throttling, and implement efficient incremental syncs.
Exchange Online Application Access Policies: Constraining Graph Application Permissions to Specific Mailboxes
Application permissions grant tenant-wide access by default. Exchange Online Application Access Policies let you scope Graph Mail.Read to a mail-enabled security group, enforcing least privilege for daemon services.
Synchronizing Microsoft 365 Users with Graph Delta Queries: A Practical Guide
Learn how to keep an external system in sync with Microsoft 365 users using Graph Delta queries. See a step‑by‑step example, paging logic, and how to handle deletions and expired links.
Choosing the Right Microsoft Graph Authentication Flow: Delegated vs. Application Permissions
Decide between Delegated and Application permissions for Microsoft Graph API. Learn when to use Auth Code, Client Credentials, or OBO flows and how to verify tokens.
Handling Microsoft Graph Throttling: Why Naive Retries Make 429s Worse
Microsoft Graph 429 throttling gets worse with naive retries. Learn the Retry-After-aware backoff pattern, why you shouldn't double-wrap SDK retries, and how to cut request volume instead.
Microsoft Graph Batching: Optimizing Bulk Operations vs. Individual Requests
Learn when to use Microsoft Graph $batch to bundle up to 20 requests, how to handle partial failures, and the critical trade-offs between batching and individual API calls.
Using Microsoft Graph delta queries to sync changes incrementally in Microsoft 365
Sync only changed users, groups, or messages with Microsoft Graph delta queries: store deltaLinks verbatim, handle tombstones, survive token expiry, with a worked C# example.
