The deck document

A deck is a JSON array of steps, at most 200. Steps count from 0, and a person reading the editor’s filmstrip counts from 1, so their “slide 6” is step 5. There is no mandatory opener: a deck made before 1 Oct 2026 may carry a join step, and the editor turns one into an ordinary slide with the join WIDGET on it the moment the deck is opened or presented. A slide step is a page (or a blank) with things floating on it: up to 4 polls, 8 text boxes, 8 shapes and 4 images. A poll step is one poll filling the screen. Positions are fractions of the slide, 0 to 1. A bare array is document version 1.

`kind`	”join”	yes

Step: slide

property	type	required	meaning
`id`	string, up to 64 characters	no	Stable id. Omit it and the server makes one.
`kind`	”slide”	yes
`pageIndex`	integer 0 to 199, or null	yes	The uploaded page behind the slide; null is a blank slide
`overlays`	list of object (id, poll, rect, style, z, locked, prevRect), up to 4	yes
`texts`	list of object (id, text, rect, z, style), up to 8	no
`shapes`	list of object (id, rect, z, style, prevRect), up to 8	no
`images`	list of object (id, rect, z, dataUrl, fit, shadow, outline, outlineColor, radius, prevRect, original), up to 4	no
`notes`	string, up to 2000 characters	no	Presenter-only speaker notes

Step: poll

property	type	required	meaning
`id`	string, up to 64 characters	no	Stable id. Omit it and the server makes one.
`kind`	”poll”	yes
`poll`	object (type, prompt, timeLimitSec, options, multiSelect, correctIndex, quizView, orderIsAnswer, optionImages, groups, targets, targetLabel, estimateMin, estimateMax, answer, dimensions, radarMax, radarLow, radarHigh, moderated, wheelSource, wheelNames, place, placeTheme, accent, colorMode, optionColors, showPercent, showCount, mcStyle, imgStyle, totStyle, rankStyle, hpStyle, scaleStyle, npsStyle, estStyle, wcStyle, mapStyle)	yes
`notes`	string, up to 2000 characters	no	Presenter-only speaker notes

Overlay (a poll floating on a slide)

property	type	required	meaning
`id`	string, up to 64 characters	no	Stable id. Omit it and the server makes one.
`poll`	object (type, prompt, timeLimitSec, options, multiSelect, correctIndex, quizView, orderIsAnswer, optionImages, groups, targets, targetLabel, estimateMin, estimateMax, answer, dimensions, radarMax, radarLow, radarHigh, moderated, wheelSource, wheelNames, place, placeTheme, accent, colorMode, optionColors, showPercent, showCount, mcStyle, imgStyle, totStyle, rankStyle, hpStyle, scaleStyle, npsStyle, estStyle, wcStyle, mapStyle)	yes
`rect`	object (x, y, w, h)	no	Where the card sits; left out, the bottom-right quarter
`style`	object (variant, accent, background, radius, shadow, outline, outlineColor, showPercent, showCount, showJoin, rotation, colorMode, optionColors, counter, showTitle, titleSize, titleColor, titleBold, titleAlign, textFont)	no	How the card is drawn; left out, the house default
`z`	number	no	Stacking order among the slide’s elements
`locked`	true or false	no
`prevRect`	object (x, y, w, h)	no	The size to restore after the full-page toggle

Any widget can float on a slide. Put the card over a screenshot, a picture or empty space, never over the slide’s own text; when the corner you had in mind holds text, take the one with the picture, and when the whole slide is text, use a full-screen poll step instead. A card lower than 45% of the slide has no room for its answers, and some looks need more (a map 35% wide and 55% high, a bullet or an NPS score 55% high, a sunburst 45% wide, a swarm 50% wide); the warning names the look’s own minimum. The card must stay on the slide, x + w and y + h at most 1, and the API refuses one that does not. Leave rect and style out for the house card in the bottom-right quarter. The card’s variant is read by multiple choice; the other widgets draw their own look. Check a placement three ways. get_screenshot shows the card on the real page; with annotate it draws every element’s box and name on the picture, the clashing ones in red, and it names the PDF page’s own words a card or text box hides (coversPageText). get_step and get_screenshot return every element’s rect and the pairs that overlap. And every read and write answers with warnings: a card under its look’s minimum size (30% of the slide’s width and 45% of its height for most, more for a few), or a card or text box over another card or text box. Warnings do not stop a room; fix them anyway. The picture has the last word on size, because how small a card can go depends on its look: get_screenshot also returns measured and warns when a card’s or text box’s content is cut off by its box, or a card’s biggest answer text is drawn under 13 pixels high on the 1600-pixel slide.

Widgets

Every poll has a type, a prompt and, where it takes answers, options. The tables list only the properties that type reads; anything else is dropped on save. A look is chosen per widget; the first is the default. To present lists what the readiness check asks for before a room can start; a deck can be saved without it. The API runs the check for you: reading a deck answers with ready and problems, and so does every write, each problem naming the step, the card and the property.

`prompt`	string, up to 140 characters	yes	The question, as it reads on screen
`timeLimitSec`	integer 5 to 600, or null	no	Seconds people get to answer; null means no countdown
`place`	object (label, lat, lon, zoom, radiusKm)	no	Place map: the place people drop a pin on, and how many kilometres around it the map shows (radiusKm)
`placeTheme`	one of standard, light, dark, plain, relief, satellite	no	Place map: the map tiles. The editor offers five — standard, light, dark, relief, satellite. `plain` is the name light had for one day and still draws the same canvas, so a deck saved with it keeps working.
