Data Flow

Understanding how messages flow through the HORISEN platform is essential for building robust messaging solutions. The data flow documentation provides detailed insights into how SMS and MNP queries are processed, routed, and delivered through our infrastructure.

These diagrams and explanations help you visualize the complete journey of messages and number portability lookups, from initial submission through our APIs to final delivery and response handling.

The SMS Data Flow section covers message delivery scenarios over both SMPP and SS7, including MT delivery to mobile subscribers, MO messages sent toward enterprise customers, roaming cases, retry profile behavior for GSM MAP, MTP, and SCCP error codes, and incoming SMS MT/MO handling.

The MNP Data Flow section illustrates how number portability lookups are resolved across the different lookup methods supported by the platform - SS7, ENUM, and the MNP HTTP API - so you can understand which components are involved at each step of a query.
