In your app
A controller answers a route on your app: it callscreateForm() and returns the answer.
Add the controller
app/controllers/create_form_controller.ts
Add the route
start/routes.ts
.use(middleware.auth())): it acts with your key’s access.Call it

A
Form. Form content type. Read its properties (form.title): each says whether the site always sends it. The example answer is the site’s wire JSON: some keys differ from the property names (_id → id, _form → form, _destination → destination).Always sent. Its title: the name it goes by in every list, and the heading of its page where it has one.
Always sent. The URL name: lowercase words joined by hyphens (letters outside a–z, even emoji, are kept).
Always sent. Select whether this content is public or private. One of
public, loginRequired; a newer site may send others, so keep a fallback.Always sent. The “from” address on this form’s emails. A new form starts with the Email in Site settings → Brand; change it here for this form.
Always sent. The document’s id. On a type with drafts it ends in its locale and mode (
…:en:published, …:en:draft): the part before the first colon is its aposDocId, shared by both copies. The {_id} the type’s routes take.Sometimes sent:

Errors
Nothing to catch: the SDK retries what is safe, and throws the rest as the classes below. Your exception handler turns them into your app’s own answers, once for every call (see Map SDK errors to responses); catch only what you want to react to here.
The site refused what was sent:
errors lists each field’s problem, siteMessage the first.Retried first: No. Read: errors (field → messages), siteMessage.The API key is missing or refused (malformed, revoked, expired), or a signature its signing mode needs is missing or stale.Retried first: No. Read:
siteMessage, errorName, data.The key may not do this: a scope it lacks, or an address outside its allowlist.
siteMessage names it.Retried first: No. Read: siteMessage, errorName, data.Nothing matches, or the caller may not see it.Retried first: No. Read:
siteMessage, errorName, data.The site failed. Its logs say why.Retried first: No: a write may have landed. Read:
siteMessage, errorName, data.No answer: DNS, a refused connection, TLS, or the timeout (15 s per attempt by default).Retried first: Only when nothing reached the site (
neverConnected()); never after a timeout, when it may have landed. Read: reason, neverConnected.The client refused to send it (e.g. a path segment of
..); the site never saw it.Retried first: No. Read: reason (what to change).Any other status, or a success whose JSON doesn’t match this SDK version’s types (update the SDK).Retried first: No. Read:
reason, status.sites.forSite('acme') named a slug config/attract.ts doesn’t list (with the keys in the database: no row in attract_api_keys).Retried first: No: nothing was sent. Read: message, slug.Behavior
- Access: an API key with
content:forms:write(or a master above it:content:forms:all,content:all,admin:all). In published mode (the default) it goes live too, so the key also needscontent:forms:publish(or a master above it); sendaposMode=draftto change only the draft. A signed-in person may call it as far as their own permissions allow; anyone else gets 403. - Rate limit: the key’s own writes-per-minute limit, set when the key is created (default 120); over it, 429 with
Retry-After. The client waits and retries for you; you seeRateLimitedonly if that runs out. - Retries: a write is sent again only after a 429 (refused before it acted) or when it never reached the site. After a timeout or a 5xx it may have landed: check before you send it again.
- Timeout: 15 s per attempt by default; raise
timeout(milliseconds) inconfig/attract.tsfor longer.
Test it
It calls the controller above with the SDK faked:fakeAttract() puts the fake in the container for this one test, and it answers every call with a valid example, so nothing leaves your machine and no key is read. Save it as tests/unit/forms_create_form.spec.ts, then run your tests:
tests/unit/forms_create_form.spec.ts
Terminal
forms.createForm with factories.Form({...}), the fields you give over a valid example.
tests/unit/forms_create_form_answers.spec.ts
