Can you please help us in finding the root cause?

Since the /sms endpoint rate limit group is Medium, meaning 40 API calls (40 messages) per 60 seconds. You should call the endpoint following the Medium rate limit. The best approach is to send a message every 1.5 secs (DO NOT calling as fast as possible then wait for the next window)

Please read [this article][1] and use the 2 option (Call and wait based on the average rate limit)

The header returns a special sms group which may not be applied to your app and we are investigate this.

@Nirmal Babu This response is actually coming from our API gateway which helps us manage the throughput of any given operation or endpoint. Your application is being "throttled" meaning it is sending too many requests within a given time window. The error will go away in time. To learn more about throttling and rate limits, go here:
