# API limits

#### API limits for Azure DevOps and Azure DevOps Server outline the restrictions on requests that can affect how Xopero ONE interacts with your data.

## Azure DevOps

Rate limits enhance security by preventing an overwhelming number of requests that could disrupt, block, or destabilize the application's functionality—the system enforces these limits for stability. For more information, visit [the official **Microsoft Learn** website](https://learn.microsoft.com/en-us/azure/devops/integrate/concepts/rate-limits?view=azure-devops).

{% hint style="danger" %}
Unfortunately, unlike other **DevOps**, **Microsoft** does not provide information about the exact number of queries that can be sent in a given time period.

## Azure DevOps Server

In **Azure DevOps Server** (on-premises), **API** limits are flexible and depend on server resources and configuration. Unlike the cloud version, there are no fixed, global request limits—administrators set performance parameters and limits tailored to the organization's specific needs.
