# Introduction

__Date__ 2026-08-12

__Status__ Public

Greetings and Salutations, you, the "client" are reading this document in an effort to connect with Tychron via the available APIs and channels henceforth referred to as the "system", or to understand processes that Tychron has.

This document should be considered a companion document to the publicly available documentation:

* [Tychron Docs](https://docs.tychron.com/)
* [API Reference](https://api.atlas.tychron.online/api/v1/swaggerui)

The Tychron Docs provides information on the publicly available APIs, it only houses more mainline features: SMS, MMS, CNAM, LRN/E and Messaging Carrier Lookup (MCL).

The API Reference page with the Open API document shows the availability of the management and provisioning APIs, however it does not contain usage examples, neither the order in which API calls should be made for certain processes.

This document covers the processes and examples of using those APIs.

If after reading this document, you are still unclear of how to complete an action, do not be afraid to contact Tychron Support for further support.

__Note__ The information provided in this document is subject to change in a non-breaking manner,
it may include additional information or corrections, but fundamental functionality shall remain similar.
