## What breaks

Azure Resource Manager retires the Custom Resource Provider (CuRP) feature by 31 Oct 2026. From July 31, 2026, creates, updates, patches, and actions to custom resources and resource providers are blocked. From that point, custom resources and resource providers can only be read and deleted. Microsoft scheduled a scream test on October 27, 2025 as part of the deprecation.

## What to do

1. If the scenario only involves triggering an endpoint without the need for persistent resource management, consider [Deployment Scripts](https://learn.microsoft.com/en-us/azure/azure-resource-manager/templates/deployment-script-template).
2. If the same scenario uses Bicep, consider [Bicep Extensions](https://learn.microsoft.com/en-us/azure/azure-resource-manager/bicep/bicep-extension).
3. If the scenario involves triggering several different endpoints or services, consider [Azure Functions](https://learn.microsoft.com/en-us/azure/azure-functions/functions-overview).
4. For questions, ask your Microsoft account manager to email curpdeprecation@microsoft.com with your name, company name, email contact, and subscription ID.

## Replacement

Not stated by vendor.
