Embed API

Put the offering notice on your own website.

You do not need FTP, cPanel, or server privileges. The issuer's web person pastes one snippet. The card is rendered from Sprowtt so price, dates, and legends stay in sync with the workspace — and it appears on the issuer's own website, which is where a notice of the issuer's offering belongs.

Method 1

Script embed

Lightest. The script injects an iframe from our origin. Send this to whoever edits the homepage.

Method 2

iframe embed

Strongest isolation. Good for Webflow, Squarespace, Wix and WordPress HTML blocks.

Method 3

Hosted subdomain

raise.issuerdomain.com, pointed at Sprowtt with a CNAME. Still the issuer's page — no FTP, no cPanel, no server privileges.

What the issuer does, in four steps

1
Choose the offering. A public card is only for a room counsel has confirmed may be shown. A Rule 506(b) room is invitation-only and will not render on a public homepage.
2
If counsel has cleared the communication, publish the issuer-approved notice from the Offerings tab so the card goes live.
3
Copy one snippet below. Email it to your web person: "Paste this where we want the notice. Please do not redesign the card."
4
They paste it. Sprowtt draws the card from the workspace, so when you change price, dates or legends here, the issuer's site updates with it.

The gate

What each room will and will not render publicly

The rule is enforced where the card is built, not in the instructions. Somebody pasting the snippet in the wrong place cannot turn a private offering into a public one.

Room	Renders on a public page	Legend carried on the card
Rule 506(b) invite room	Never — invitation token required	Private offering. Access by invitation only. This material is not an offer to the public and may not be reproduced or forwarded.
Rule 506(c) offering	Yes	Offered only to accredited investors under Rule 506(c). The issuer is responsible for verifying accredited status. Not an offer where prohibited.
Regulation A test the waters	Yes	Testing the waters. No money or other consideration is being solicited, and none will be accepted. No offer to buy securities can be accepted and no part of the purchase price can be received until an offering statement is qualified. An indication of interest involves no obligation or commitment of any kind.
Rule 147A intrastate room	Yes	Sales will be made only to residents of the issuer's state of residence. Offers may be viewed elsewhere. This is not an offer to sell to a non-resident.

A card is withheld — and the reason recorded for the issuer — when the offering is a draft, is closed, has a counsel hold on it, has no published notice, or when the subscription is unpaid. The public page simply shows nothing rather than stale terms.

Every render is logged: the offering, the host that asked for it, and whether a token was used. That is how an issuer can see where its own card is live, and how a card that has been copied somewhere unexpected gets noticed.

Firms on the counsel plan get API keys and webhooks, so the notice, the indication feed and the render log reach your own systems too.
