What it accepts​

A short opener naming the kind of post: a label, an optional line and the brand's logo. metaData is the post's title, descriptions and hashtags and is never drawn.

FieldTypeRequiredLimitWhat it is
clipDatagroupyesClip data: Everything drawn: the label, an optional line under it, and the look.
clipData.labeltextyesup to 18 charactersLabel: What kind of post follows, such as BREAKING, NEW, TIP, WEEKLY RECAP or PART 2.
clipData.linetextup to 32 charactersLine: A few words under the label, such as Markets or The figures.
clipData.lookgroupLook: How the stinger looks and moves within its style. Leave a switch out, or set it to the style's own, and the style decides.
clipData.look.themeenumauto, brand, light, dark, boldTheme: The style's own choice; your brand's own colours and background; a light or dark page tinted with your brand colour; or your brand colour as the page.
clipData.look.paceenumauto, calm, standard, punchyPace: How things arrive: the style's own rhythm, calm fades, a standard rhythm, or punchy slams and cuts.
clipData.look.cornersenumauto, square, soft, roundCorners: The shape of cards, panels and marks.
clipData.look.alignenumauto, start, centreText alignment: Where the text lines up.
clipData.look.logoenumauto, freeLogo: The style's own: the logo on the style's plate (a card, a disc, a badge) 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.
metaDatagroupMeta 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.titletextup to 100 charactersTitle: 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.captionTinytextup to 200 charactersTiny description (Pinterest, Threads, X): Up to 200 characters. The brand's description, link and hashtags follow it within the platform's limit.
metaData.captionShorttextup to 500 charactersShort description (Telegram, Threema, WeChat, WhatsApp): Up to 500 characters. The brand's description, link and hashtags follow it within the platform's limit.
metaData.captionMediumtextup to 1500 charactersMedium 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.hashtagslistup to 15Hashtags: Written without the #. Up to 15, which every platform takes.
metaData.hashtags[]textup to 60 charactersHashtag

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 422 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.
