REST API

The most feature rich API that Sinch offers is the SMS REST API. Single messages, scheduled batch send-outs, using message templates and more.

Introduction

The REST Messaging API is designed to be a simple and powerful tool for large scale messaging with features such as:

  • Use a convenient HTTP interface.
  • Send a message to more than one recipient in the same request.
  • Send text messages with up to 1600 characters.
  • Organize your frequent recipients into groups.
  • Send messages at a later time with scheduling.
  • Customize your message for each recipient using parameterization.
  • Receive messages from end users with MO support.
  • Automatic default originator selection support for messages without originator.
  • Receive inbound messages and delivery notifications via HTTP or AWS SNS.
