Tech and industry (Energy and utilities), Sustainability

Up to four sustainability figures against the year before, each in a housing of flaps: its value with its unit, the change in your up or down colour as you say it is better or not, the year before, its period and its source, and how the figures are measured under the headline, the supplier's notice at the foot throughout. The board ripples, then each figure is told in turn, before a line, the button and the presenter. Seven to thirteen seconds: it grows with the number of figures.

What it accepts

One to four sustainability figures against the year before, each in a housing of flaps: value and unit, the change in your up or down colour, the year before, its period and source, and how the figures are measured, your notice throughout. Each told in turn, then a line, the button and your presenter. Seven to thirteen seconds. metaData is never drawn.

Field	Type	Required	Limit	What it is
clipData	group	yes		Clip data: Everything drawn in the clip: the figures with their values, units, periods, changes, years before and sources, how they are measured, the words in the housings, the line at the end, the call to action and your notice.
clipData.section	text		up to 32 characters	Section: The section in the header, painted as a sign beside your title line, such as Sustainability.
clipData.kicker	text		up to 40 characters	Kicker: A short line above the headline, such as Our 2025 figures.
clipData.headline	text		up to 64 characters	Headline: The headline, set large. Say what the figures show, plainly; never claim more than they do.
clipData.basis	text	yes	up to 160 characters	How the figures are measured: The method, the scope and the standard behind the figures, shown under the headline on every frame, such as Scope 1 and 2, market-based, GHG Protocol. A claim without its basis is not shown.
clipData.figures	list	yes	at least 1, up to 4	Figures: One to four sustainability figures, each a housing of its own, told in turn from the first. Each is drawn exactly as sent. The change is the one you send; the clip works out nothing.
clipData.figures[]	group			Figure
clipData.figures[].name	text	yes	up to 40 characters	Figure: What the figure measures, such as CO2 per kWh supplied or Renewables in our power mix.
clipData.figures[].value	number	yes	4 decimals	Value: The figure for the period, drawn exactly as sent, with its own decimals.
clipData.figures[].unit	text	yes	up to 24 characters	Unit: The unit of the figure, such as g CO2e/kWh, % or MWh. Required: a figure is never shown without its unit.
clipData.figures[].period	text	yes	up to 40 characters	Period: The period the figure covers, such as 2025, full year. Required: a figure is never shown without its period.
clipData.figures[].previous	number		4 decimals	Year before: The same figure for the year before, drawn exactly as sent, in the same unit. Left out, no year before is drawn.
clipData.figures[].previousPeriod	text		up to 40 characters	Period of the year before: The period of the year before, such as 2024, full year.
clipData.figures[].change	number		2 decimals	Change: The change against the year before, in percent, as you work it out, such as -12 for twelve percent lower. Drawn with its sign, exactly as sent. Left out, no change is drawn.
clipData.figures[].better	boolean			The change is better: Whether the change is an improvement: yes sets it in your up colour, no in your down colour. Left out, it is set in your brand colour. A falling figure can be better (emissions) or worse (renewables), so only you say.
clipData.figures[].source	text	yes	up to 60 characters	Source: Where the figure comes from, such as Source: Sustainability report 2025, page 14. Required: a figure is never shown without its source.

clipData.look	group			Look: How the clip looks and moves. The same six switches in every format (theme, pace, corners, alignment, logo, logo size). Leave any out for the package's default: dark, standard pace, softly rounded, text at the start.
clipData.look.theme	enum		brand, light, dark, bold	Theme: Brand: your brand's own colours and background. Light or dark: a page tinted with your brand colour. Bold: your brand colour as the page.

locales carries other languages: under each language code, the parts of clipData and metaData that differ, laid over the default, so a language with no copy still renders.

A picture is always a file from your media library: media:// followed by its id or its name. Anything the table does not list is refused, and so is anything over its limit, with a 400 schema_validation error that names the field.

Delivery JSON

Your own system sends this to one of your streams, POST /v1/stream, and every channel listening to that stream draws it with its template. data is the document described above; a stream with an empty field map passes it to the template unchanged. Try it first on POST /v1/stream/validate, which answers the same without publishing anything. Streams and feeds explains the rest, including how to map a document of your own shape instead.

The delivery names no version: which build draws it is the channel's choice, the newest of its variant or the one it is pinned to. eventId is a ULID you make once per event: sending the same one again changes nothing. occurredAt is when the thing happened, not when you sent it. locale is the language of the text in data, and data.locales carries other languages beside it.
