Version 2.20180712.0 (2018-07-12)
We introduce Square API versions. Square-Version
is 2018-07-12 for this SDK.
How versioning works
Square API versions (Square-Version
) track changes in the evolution of Connect
v2 APIs. The Square-Version
naming scheme is YYYY-MM-DD
, which indicates
the date the version was released. Connect v1 APIs are not versioned. Square
continues to support Connect v1, but future releases will focus on improving
Connect v2 functionality.
By default, new Square applications are pinned to the version current at the
time the application was created in the Square Application Dashboard. Pinning an
application sets the default Square-Version
for the application. The default
Square-Version
of an application can be reviewed and updated at any time on
the settings pages for the application.
Versioning and SDKs
When a new Square-Version
is released, new Connect SDKs are publish on GitHub
and various package management systems. SDK updates follow the version
convention of the associated language and manager but include the related
Square-Version
in the SDK version. For example, Connect SDKs tied to version
2018-01-04
might look like {SDK_VERSION}.20180104.{VERSION_INCREMENT}
.
While SDK versions can be mapped to a related Square-version, SDK versions
follow an independent, incremental versioning scheme to allow updates and
improvements to the SDKs outside of Square-Version
updates.
Migrating to new versions
In most cases, Square-version migration should be straightforward, with known
differences listed in the related Change Log.
To test migrations, developers can override the default Square-Version
of an
application by explicitly setting the preferred Square-Version
in the HTTP
header of the Connect v2 API request for REST calls. Requesting an API version
that does not exist returns an error. Successful API responses include the
Square-Version
header to indicate the API version used to process request.
Connect SDK versions are locked to specific API versions and cannot be
overwritten. Instead, the SDK must be upgraded to work with new API versions.
