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 reaction, commentary and review channels. Built to be read at 320 px wide: a few huge elements, the words shrink to fit and stop at three lines, the badge and channel end with an ellipsis. Without a face photo the circle holds the emoji; without the subject image the frame shows a halftone with a big ?!. Wide frames put the subject on the left and the face on the right; vertical ones stack subject, words and face.
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.
| Field | Type | Description | Example |
|---|---|---|---|
title |
text | Two or three loud words, e.g. I tried $900 sneakers. default: Wait, what? | I tried $900 sneakers |
badge |
text | Tag in the top left corner, e.g. Honest review. | Honest review |
emoji |
text | One emoji next to the face. | 😳 |
channel |
text | Channel name in the top right corner. | Maya Reacts |
face_photo |
image URL | Your face, ideally mid-reaction; it is cropped to a circle. | https://example.com/images/creator-face.jpg |
subject_image |
image URL | What you react to: a product, a screenshot, a still from the video. | https://example.com/images/sneakers.jpg |
accent |
colour | Brand colour as hex, e.g. #6366f1. Drives buttons, highlights and the background glow. default: #facc15 | #facc15 |
theme |
dark | light | Colour scheme: dark or light. | — |

accent and theme change per request. 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.
