Microsoft Azure API Rate Limits

Azure Resource Manager enforces rate limits on API requests to prevent overconsumption and ensure fair usage across tenants and subscriptions. When the limit is exceeded, Azure returns HTTP status code 429 (Too Many Requests). Monitor these limits to understand your API consumption patterns and avoid throttling.

For more information, see Azure Resource Manager throttling.

Prerequisites

• Integration with Microsoft Azure, as detailed in Azure Metrics.
• Integration version 1.8.0 or later.
