You can call the 'OnStatusRequest' method in the script immediately after sending the message, or after a small delay with a 'Thread.Sleep(2000);' call if you need to wait 2 seconds for the status to update on the SMS service.

Using 'Thread.Sleep(2000)' causes the script to pause and decreases message throughput, a better (but slightly more complicated) way to wait a few seconds before calling the 'OnStatusRequest' method is to use a timer or the 'Task.Delay' method. With both methods the script keeps processing the outgoing messages during the delay. The 'Task.Delay' method is probably the easiest to implement.

Hello Ricardo,

When you set the 'sendStatusRequest' parameter of the 'PostSendResult' method in the script to 'true', the script will call the 'OnStatusRequest' method one or more times in increasing time intervals until you call the 'PostSendResultUpdate' method. In the 'sendStatusRequest' method, you can send a DLR request to the SMS service and set the final status of the message when it is available.

You can find and example on how to use the 'OnStatusRequest' method in the 'BulkSMS.com.cs' script in the Scripting Pack on the download page of this website.
