Hi Richard,

I understood you want to get the response examples for HTTP status code 429 returned by Azure services when too many requests are sent in a given amount of time.

About the example as I know there aren't example docuemented however the response includes a Retry-After value, which specifies the number of seconds your application should wait before sending the next request, this applies to Azure Service Bus, Azure Event Hub, Azure Event Grid, and Azure Blob Storage. So If you want to create a mechanism trigger by this response code I suggest you to check below documentation:

• https://learn.microsoft.com/en-us/azure/architecture/best-practices/retry-service-specific#retry-usage-guidance
• https://learn.microsoft.com/en-us/answers/questions/26600/my-application-receives-http-status-code-429-respo
• https://learn.microsoft.com/en-us/azure/azure-resource-manager/management/request-limits-and-throttling#error-code
• https://learn.microsoft.com/en-us/troubleshoot/azure/virtual-machines/windows/troubleshooting-throttling-errors#throttling-error-details

If the information helped address your question, please Accept the answer.
