Microsoft Word Rate Limits

Microsoft Word programmatic surfaces — the Word JavaScript API (Office.js Add-ins) executing in-app, and the Microsoft Graph Word / OneDrive endpoints — inherit Microsoft Graph's per-tenant / per-app throttling. Graph throttling is dynamic (based on resource consumption) rather than a single published per-second number; OneDrive enforces a documented per-user-per-app limit. 429 responses carry Retry-After.

Microsoft Word Rate Limits is the machine-readable rate-limit profile for Microsoft Word on the APIs.io network, in the API Commons Rate Limits shape.

It captures 4 rate-limit definitions, measuring varies.

Limit state is signalled in the retryAfter, ratelimitLimit, ratelimitRemaining, and ratelimitReset response headers, and an exhausted limit returns HTTP 429.

This profile was written by API Evangelist and has not been verified against a page the provider published; treat every limit as unconfirmed until a dated transcription replaces it.

The profile also includes 4 backoff/retry policies defined and response codes documented for throttled and serviceUnavailable.

Tagged areas include Rate Limiting, Productivity, Documents, and Microsoft.

Policies

Honor Retry-After
Microsoft Graph and OneDrive return 429 / 503 with Retry-After. Pause for that many seconds, then retry with exponential backoff and jitter.
Decorate user-agent
Use a meaningful User-Agent / x-anchorMailbox header per Graph guidance to reduce throttling impact.
Use ChangeNotifications, not polling
Subscribe to OneDrive change notifications instead of polling /drive/root/delta to avoid hitting per-minute caps.
Batch with $batch
Use Microsoft Graph $batch endpoints (up to 20 requests) to reduce per-call overhead.
