Tech and industry (Automotive and mobility), Trade-in

What your car is worth: a headline in wide capitals, the date of the valuation with what the values depend on, always beside the values, and up to three example cars set like a film's credits, each with its model, age, mileage and value as sent. A picture, where there is one, pushes in slowly behind the title. Each car is then told on a card of its own, before the button and the presenter. The legal line stands throughout. About two seconds longer per car.

What it accepts

What your car is worth, as a dealer's film asks it: a headline in wide capitals, the date of the valuation with what the values depend on beside them, and up to three example cars as credits, each with its model, age, mileage and value as sent. A picture is optional. Each car is then told on a card, before the dealer's button. About two seconds more per car. metaData is never drawn.

Field	Type	Required	Limit	What it is
clipData	group	yes		Clip data: Everything drawn in the clip: your headline, an optional picture, the date of the valuation and what the values depend on, the example cars with their ages, mileages and values, the call to action and your legal line.
clipData.section	text		up to 32 characters	Section: The section in the header, beside your title line, such as Trade-in or Part exchange.
clipData.kicker	text		up to 40 characters	Kicker: A short line above the headline, such as Part exchange.
clipData.title	text	yes	up to 48 characters	Headline: The headline, set large in wide capitals, such as What is your car worth?
clipData.tagline	text		up to 90 characters	Line under the headline: One line under the headline, set in italics.
clipData.picture	image		media:// file from the media library, alt text up to 120 characters	Picture (optional): A car or a forecourt, from the media library: a landscape photograph with the car in the middle, low in the frame, works best. It fills the film window and pushes in slowly. Leave it out and the clip is words and values on the page. A picture is never required, and no value is tied to the car pictured.
clipData.valuation	group	yes		Valuation: When the values were worked out, and what they depend on. Shown beside the values on every frame that shows them: a value never stands without its date and what it depends on.
clipData.valuation.lead	text		up to 24 characters	Before the date: A word or two set small above the date, such as Valued on.
clipData.valuation.date	text	yes	up to 32 characters	Date of the valuation: The day the values were worked out, as a date such as 2026-10-12. It is written out the way the channel's language writes it.
clipData.valuation.dependsOn	text	yes	up to 200 characters	What the values depend on: What the values depend on, such as condition, service history, options and the market on that date. Required; never cut: a long one takes more lines.
clipData.valuation.currency	text	yes	up to 3 characters	Currency: The values' currency as a three-letter code, such as EUR, GBP or USD.
clipData.valuation.mileageUnit	text		up to 12 characters	Mileage unit: Set after each mileage, such as miles or km.
clipData.cars	list	yes	up to 3	Example cars: Up to three example cars set like a film's credits, then each told on a card of its own, its value counting to exactly what is sent. Each adds nearly two seconds.
clipData.cars[]	group			Car
clipData.cars[].model	text	yes	up to 40 characters	Model: The car, such as Corvane Pico 1.2 Hybrid.
clipData.cars[].age	text		up to 28 characters	Age: How old it is, as you say it, such as 3 years old or Registered 2023.
clipData.cars[].mileage	number		from 0, 0 decimals	Mileage: The mileage as a number, such as 28000, set the way the channel's language writes it.
clipData.cars[].value	number	yes	from 0, 2 decimals	Value: What it is worth in the valuation's currency, as a number.
clipData.cta	group			Call to action: The button at the end and the line under it, such as a web address, a handle or a phone number.
clipData.cta.label	text	yes	up to 28 characters	Button: What the button says.
clipData.cta.detail	text		up to 48 characters	Line under it: An address, a handle, an app, a phone number.

clipData.footnote	text		up to 200 characters	Small print: Any other line that must be shown.
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: the dark theme, calm, square corners, centred.
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.
clipData.look.pace	enum		calm, standard, punchy	Pace: How things arrive: calm fades, a standard rhythm, or punchy slams and hard cuts.
clipData.look.corners	enum		square, soft, round	Corners: The shape of cards, pictures and buttons.
clipData.look.align	enum		start, centre	Text alignment: Where the text lines up.
clipData.look.logo	enum		auto, free	Logo: The style's own: the logo on a small plate so it reads on any page. As it is: the logo whole, with no plate, frame or crop, for a logo made to stand on the page, such as one with a transparent background. As it is, make sure your logo reads on the page of the theme you choose.
clipData.look.logoSize	enum		auto, small, large	Logo size: Standard is the style's own size. Small draws the logo a fifth smaller, with its plate. Large draws it a quarter larger wherever the style has room for it, and at the standard size where it has none.
metaData	group			Meta data: Everything about the post that is never drawn in the clip: its title, its description in four lengths, one per kind of platform, and its hashtags. Reelwire adds the brand's description, link and hashtags after it. Left out, the post text is generated from the clip data.
metaData.title	text		up to 100 characters	Title: Used where the platform has a title of its own: Facebook Feed, LinkedIn, Pinterest and YouTube. Up to 100 characters, which every one of them takes.
metaData.captionTiny	text		up to 200 characters	Tiny description (Pinterest, Threads, X): Up to 200 characters. The brand's description, link and hashtags follow it within the platform's limit.
metaData.captionShort	text		up to 500 characters	Short description (Telegram, Threema, WeChat, WhatsApp): Up to 500 characters. The brand's description, link and hashtags follow it within the platform's limit.

metaData.captionLong	text		up to 4000 characters	Long description (Facebook Feed, YouTube): Up to 4000 characters. The brand's description, link and hashtags follow it within the platform's limit.
metaData.hashtags	list		up to 15	Hashtags: Written without the #. Up to 15, which every platform takes.
metaData.hashtags[]	text		up to 60 characters	Hashtag

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.

Ask Reelwire for the whole JSON Schema, the document your content is checked against, without signing in:

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.
