Microsoft Azure Private Link Rate Limits

Private Link operations are Azure Resource Manager control-plane calls against management.azure.com, so they inherit ARM throttling, not a product-specific quota. Two layers apply at once: the ARM gateway token bucket (per subscription, per service principal, per operation type, applied per region) and the Microsoft.Network resource provider's own per-subscription-per-region ceiling. Whichever empties first throttles the call. This file replaces a 2026-05-04 scaffold that carried invented free/pro/enterprise request quotas; none of those numbers came from Microsoft.

Microsoft Azure Private Link Rate Limits is the machine-readable rate-limit profile for Microsoft Azure Private Link on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 6 rate-limit definitions, measuring requests.

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

Tagged areas include Rate Limiting, Throttling, and Azure Resource Manager.

Policies

Retry-After is authoritative
On a 429 the response carries Retry-After in seconds. Sending before it elapses is not processed and returns a fresh, longer retry value. Azure SDKs implement this automatically.
Free and trial subscriptions are lower
Microsoft states the documented buckets may be smaller for free or trial customers, without publishing the reduced numbers.
Background job throttling
ARM separately throttles platform background jobs; the symptom is "The request for subscription could not be processed due to an excessive volume of traffic". A caller has no control over it.
429 is not always a quota
Microsoft warns that some resource providers return 429 for transient overload or target-resource state, not for a quota the caller consumed.
