Styles

Choose from built-in professional visual styles or create your own custom styles to match your brand and content. Each style has a unique ID that you'll need to pass as the style_id parameter in your API requests. In the Napkin app, this same value is shown as the brand ID.

You can also read the built-in styles from the API, which is easier than copying an ID from this page:

curl https://api.napkin.ai/v1/styles \
  -H "Authorization: Bearer YOUR_TOKEN_HERE"

Each entry carries the id to pass as style_id. Custom styles you create in the app are not listed there yet; their IDs are shown in the app.

Built-in Styles

Choose from 25 professional visual styles. Each built-in style has a unique ID that you can use directly in your API requests. In the app, that same identifier is the brand ID.
