To conduct a TPS load test for your system:
Postman supports a maximum throughput of 200 TPS for load test environment only
The purpose of the load test is not to verify SMS delivery to recipients, but to evaluate your system’s capacity and performance.
SMS messages sent from the load test environment are processed only at the aggregator level and do not reach the telco level. This means they will not be delivered to actual mobile phones, and the status will remain “Pending” on Postman, not “success”.
The load test environment is designed solely for testing your system’s capabilities, allowing you to assess its performance under load conditions.
You are required to conduct your load test in the Postman load test environment only.
Postman admin portal:
Postman API base URL:
Do not conduct your load test at Postman production and test environment.
The Postman system will provide the correct request and response payloads to support your testing needs.
You can find the expected endpoints for single send for instance in the documentation .
