Tech and industry (Energy and utilities), Tariff change

A tariff change as a departures board: the unit price now and from the date it changes on flaps with its unit, the change in the brand's up or down colour, the tariff, the date and what the prices include, the standing charge old and new where sent, the supplier's notice at the foot throughout. The board ripples, the prices are told in turn, before what to do, the button and the presenter. Eleven seconds.

What it accepts

A tariff change as a departures board: the unit price now and from its date on flaps with its unit, the change in your up or down colour, the tariff, the date and what the prices include, the standing charge old and new where sent, what to do, your notice throughout. Each told in turn, then the button and your presenter. Eleven seconds. metaData is never drawn.

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.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.

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.
