A REST-style interface for sending SMS over standard web requests instead of a persistent SMPP bind, generally simpler to integrate but with different throughput and reliability trade-offs.
Why HTTP API Matters
Not every integration needs, or can justify, standing up a persistent SMPP bind. An HTTP API trades some of SMPP's raw sustained throughput for the simplicity of a stateless request your existing web stack already knows how to make, which is why it is a common starting point before volume justifies moving to SMPP.
How HTTP API Works
The application sends a single HTTP request, typically a POST with the message, destination, and credentials, and receives a synchronous response confirming the message was accepted along with a message ID. Delivery status arrives later as a webhook callback to a URL you register, rather than over the persistent connection an SMPP bind maintains.
How SMPPCenter Uses This
SMPPCenter offers a REST API alongside its SMPP bind. Many customers integrate over HTTP API first for speed of implementation, then move to a direct SMPP bind once volume or latency requirements make a persistent connection worth the extra integration effort.
