Packaging
The add-on files must be packed in ZIP format and its filename must use the .zip extension. The resulting ZIP file can contain a root folder. The name of that folder is not meaningful. Such a ZIP archive can be uploaded to the Platform Setup Application using the provided form in the Add-ons page.
Here is a sample directory structure for the ZIP
archive:
In file manifest.json: { "api_version": "0.1.0", "description": "Demonstration of an addon", "name": "sampleaddon" }
