We offer a number of different APIs and libraries that make it easy for you to use our SMS services globally, to send and receive messages.
If you are a local customer of Sinch Germany GmbH, using our domestic German platform, please contact our German support team for further assistance.
If you want to implement the Sinch Verification API please go to our Verification documentation.
What are the supported APIs?
The REST API is the most feature rich API we offer, and it is really easy to use. It allows for single messages, scheduled batch sendouts using message templates and more. You can also use our server side libraries if you like to work natively in your programming language of choice. Our SMPP interfaces are there for you if you want low level control and super low latency. If you don’t like to use any of our APIs you are welcome to use our Connect web application that will let you send SMS straight from our web site.
