Welcome to the Google Home Developer Center, the new destination for learning how to develop smart home actions. Note: You'll continue building actions in the Actions console.

Directory information

Before publishing your smart home Action, you need to provide information about your Action. This information shows up on your Google Assistant directory page.

It's important that you promote and highlight your Action's capabilities and provide everything users need to know about your Action. A good directory page includes the following details:

  • Description — A brief summary of what the Action can do and its features.
  • Icon and banner images — These images reflect your brand and differentiate your Action from other ones.

In the Actions Console, go to Deploy > Directory information to review and update your Assistant directory page.

Directory information can be specified for each language and locale your Action uses. To change to the directory information for another language, click the language at the top of the section and enter your translated information. Read localized publishing for more information.
