I am an app developer for the Zendesk App Marketplace. How can I update my contact details and app images presented within the app?
To update the app content such as author, email address, description and images in the app, the
manifest.json of the app package needs to be updated.
For more information about the expected format for manifest.json file, see the article: Publishing your app - Create content.
For more information about the image requirement and brand assets, see the article: Marketing assets.
