Octopush has developed a simple API to make implementation as simple as possible.
The SMS API Octopush supports sending very large volumes of SMS messages, to more than 220 countries in the world.

To make our system as universal and accessible as possible, we used HTTP and SMTP protocols.
The SMS HTTP API is not RESTful, but can be implemented in a single Curl call or just by calling a URL with the corresponding GET parameters.
The SMTP SMS API allows you to automate sending messages from existing automatic email systems.
Whenever possible, it is preferable to use the HTTP POST API.
Octopush actually allows you to use HTTPS for secure transfer of data to your platform.
