The Zephyr SOAP Web Services Perl Sample Code demonstrates how to access the API indirectly to implement dashboards and testing features into apps. Developers can learn to integrate by using DWIM Perl Package and SOAP Lite. More about the API at https://zephyrdocs.atlassian.net/wiki/spaces/DEVELOPER/pages/33095698/API
A good API is the secret to being able to test earlier, which means finding problems earlier in the software process. Perhaps earlier enough to prevent the delays, certainly earlier enough to save time. If you want to test earlier and be more effective, this is the place to start.
In recent years, API specification/description formats, most notably OpenAPI, have become more common and have helped standardize the once-murky definition of an API. This standardization allowed the creation of a broad ecosystem of tooling for auto-generated testing and documentation.
