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 brands, creators, stores and giveaway apps announcing a contest. Up to four steps are numbered, more are counted ("+2 more"), and long steps end in an ellipsis. A date and time in ends_at goes on the tab as Nov 8 over 23:59; text Carbon cannot read is shown as written. Without a prize photo the window shows a gift. Wide frames put the burst on the left and the tab on the bottom edge; square frames put the burst on top, and vertical frames hang the tab from the top edge.

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.
