Rate Limits & Quotas

Understand the rate limits and quotas for Microsoft Dynamics API access.

6000

Requests / Minute

Requests / Day

Important Notes

•Microsoft Dynamics includes multiple products (Dynamics 365, Dynamics GP, Dynamics NAV)
•Dynamics 365 web API throttling limits: 6,000 requests per 60 seconds (100 requests per second) per tenant
•Rate limits vary by service tier and Dynamics product
•For Dynamics 365 Customer Engagement: Service Protection API Limits apply
•Daily limits depend on licensing and subscription tier, not fixed globally
•Throttling behavior: 429 HTTP status code returned when limits exceeded
•Some operations may have different limits based on query complexity and resources used

1.
Implement exponential backoff
When you receive a 429 error, wait before retrying with increasing delays.
2.
Cache responses when possible
Store frequently accessed data locally to reduce API calls.
3.
Use batch operations
Combine multiple operations into single requests where supported.
4.
Monitor your usage
Use the Primrose dashboard to track your API usage and set alerts.

Rate Limit Errors

What happens when you exceed limits

{
  "error": {
    "code": "rate_limit_exceeded",
    "message": "Too many requests",
    "retry_after": 60
  }
}

When rate limited, the response includes a retry_after value indicating how many seconds to wait before retrying.
