We recommend using our official SDKs for easy integration of fiskaly services. The SDKs provide wrapper functions in multiple programming languages for our fiskaly client, which performs direct communication with our servers. The SDKs are updated with every release of the client.
Our SDKs and client use Semantic Versioning to provide consistent version information. The SDK version follows the client version, i.e. they must always have the same MAJOR and MINOR version number. The first two numbers of the PATCH must also be the same. Following numbers mark the revisions of the SDK.
