As part of a continuing effort to improve the experience of using Square's APIs, we've updated the examples supported in our API reference site to include all the languages for which we provide SDKs.
The new SDKs are available through most popular package managers and on GitHub:
PHP | Node.js | Ruby | Python | .NET | Java
Did you know?
We are constantly evaluating new languages to add. In the meantime, if the language you need is not supported, you can always send JSON to the endpoint URLs directly.
