Contributing Items

The Marketplace Repository in GitHub lists all officially supported Marketplace items used by the Netzo Web Platform.

We review all Marketplace items before they are published. This means that it may take some time before we can review your item.

To submit a Marketplace item for review:

  1. Fork this repository
  2. Select and copy any other item as a starting template
  3. Develop the item by modifying the copied files accordingly
  4. Add the URL of the item.json file to items.json
  5. Create a pull request

Feel free to contribute Marketplace item requests. We continuously select popular item requests (based on upvotes and other factors) to implement them and make them available in the marketplace as core items. The source code for relevant items (those with a main field in its item.json file) can be stored directly at the item's directory, feel free to contribute the item implementation as well. After a quick review they would also appear in the marketplace as community items.


To be valid, a item.json file must validate against the item.schema.json JSON Schema. You can use a tool like JSON Schema Validator for quickly testing your item.json files. The following table summarizes the fields in a item.json file.
