Sinch provides official SMS API SDKs for Python, Java, Node.js, and .NET (C#), maintained on its public GitHub organization. These libraries handle authentication, retries, and serialization. There is no dedicated official PHP SDK, only a basic tutorial using the REST API directly, and the underlying REST API can be used from any language.
