Finance (Wealth and advice), Tax year deadline

The days left to a tax deadline as a post, in a calm private office look: the headline and its line, the days to go and the deadline's date as a large light figure, and up to four allowances to use before it on dotted leaders with their amounts exactly as sent and the tax authority as the source, complete on the first frame, the firm's legal line at the foot throughout. Each allowance is then told in turn before the button and the adviser. No return is shown. About one and a half seconds longer per allowance.

What it accepts

A tax deadline: the days to go as you send them (never worked out from a clock), the deadline's date, up to four allowances to use before it with their amounts as sent, the tax authority as the source, your legal line throughout. No return is shown, so no performance warning. Eleven seconds, about one and a half seconds more per allowance. metaData is never drawn.

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.
