Finance (Wealth and advice), Adviser's letter

The quarter in the adviser's own words as a post, in a calm private office look: the letter's date under the headline and one paragraph on an engraved sheet, complete on the first frame, paged when it is long and never set smaller than a reader can read, signed with the adviser's name and role beside the presenter's portrait. The firm's legal line stays at the foot throughout, with a past performance warning when the letter needs one, before the button. Fourteen seconds.

What it accepts

The quarter in your adviser's own words: one paragraph on a letter, paged when long and never set smaller than a reader can read, signed with the adviser's name and role beside the presenter portrait, and dated. Your legal line stays at the foot, with a past performance warning if you send one. Fourteen seconds. metaData is never drawn.

Field	Type	Required	Limit	What it is
clipData	group	yes		Clip data: Everything drawn in the clip: the headline, the date, the letter, the adviser's name and role, 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 Client letter.
clipData.kicker	text		up to 40 characters	Kicker: A short line above the headline, such as Quarterly letter.
clipData.headline	text	yes	up to 64 characters	Headline: What the letter is about, set large. Describe the quarter; never promise a result here.
clipData.date	datetime	yes		Date of the letter: The day the letter is dated, such as 2026-10-01T09:00:00+01:00. It is written out in the channel's language under the headline.
clipData.letter	text	yes	up to 520 characters	The letter: The quarter in one paragraph, in your adviser's words. A long letter turns pages; none is shortened. If it quotes a return, keep to complete periods, name the period and the fee level in the text, and send the past performance warning below.
clipData.signedBy	group	yes		Signed by: Who signs the letter. The portrait beside the name is the brand's presenter picture.
clipData.signedBy.name	text	yes	up to 40 characters	Name: The adviser's name, such as Charlotte Ashby.
clipData.signedBy.role	text	yes	up to 48 characters	Role: The adviser's role, such as Chartered wealth manager.
clipData.pastPerformance	text		up to 260 characters	Past performance warning: Send this when the letter mentions a return: that past performance is not a reliable indicator of future results, as your regulator asks. Shown first in the warnings at the foot throughout. Leave empty when the letter quotes no return.
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.legal	text	yes	up to 400 characters	Legal line: Who authorises and regulates you, and that capital is at risk, as your regulator asks. Shown at the foot from the first frame to the last; a long line is set smaller, never cut.
clipData.footnote	text		up to 200 characters	Small print: Any other line that must be shown, such as that the letter is general and not personal advice.
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 brand's colours, calm, softly rounded, 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.captionMedium	text		up to 1500 characters	Medium description (Discord, Facebook Reels, Instagram, LinkedIn, Signal, Slack, TikTok): Up to 1500 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.

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.
