These are real renders from the API with the example values in the table below. Switch the size above: the same template lays itself out for all 6 sizes — send size or sizes with the request.
For creators, marketers and agencies who generate carousels slide by slide, one API call per slide. The title shrinks to fit and the hook stops at two lines; without a slide count the rail still shows six ticks, with one it draws up to twelve. Square and vertical frames, the real carousel sizes, give the title most of the page; wide frames keep the same order in a shorter column.
Fields
Every field is optional. Long text shrinks to fit instead of overflowing; an image field takes a public URL that we fetch on our side.

For anything more, copy the template into your account: you get an ordinary HTML template with the same fields that you can edit in the dashboard or through the API. If the slug is free on your account, the copy takes it — your integrations switch to your version without changing a line.
