In your app
A controller answers a route on your app: it callsgetRedirect() and returns the answer.
Add the controller
app/controllers/get_redirect_controller.ts
Add the route
start/routes.ts
Call it
Terminal
node ace serve running, it prints its answer as JSON.Find the id
id is the document’s _id, from a list. Ask the list for only the fields you need: each row is a document’s id and those fields.
AdonisJS
row.id as id. See Find an id.

Redirect. Redirect content type. Read its properties (redirect.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, _newPage → newPage).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. 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:
undefined when the site leaves it out, and it can be null. Link Type. One of internal, external; a newer site may send others, so keep a fallback.Sometimes sent:
undefined when the site leaves it out, and it can be null. The related @apostrophecms/page documents, in order (empty when none). To set it, send a list of { "_id": "…" }, one per document (one at most); a document the site can’t find is left out. At most 1 items.Sometimes sent:
undefined when the site leaves it out, and it can be null. When set, a URL; empty or null when not.Sometimes sent:
undefined when the site leaves it out, and it can be null. Redirect Type. One of 302, 301; a newer site may send others, so keep a fallback.Sometimes sent:
undefined when the site leaves it out, and it can be null. Ignore query string when matching.Sometimes sent:
undefined when the site leaves it out, and it can be null. Forward query string.Errors
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 (only a 502, 503 or 504 is retried). Read:
siteMessage, errorName, data.No answer: DNS, a refused connection, TLS, or the timeout (15 s per attempt by default).Retried first: Yes, after 0.5 s then 1 s. 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:redirects:read(or a master above it:content:redirects:all,content:all,admin:all) reads the published documents. A signed-in person may call it as far as their own permissions allow; anyone else gets 404. - Rate limit: the key’s own reads-per-minute limit, set when the key is created (default 600); over it, 429 with
Retry-After. The client waits and retries for you; you seeRateLimitedonly if that runs out. - Retries: a read is safe to repeat: the client retries it on no answer, a 502/503/504 and a 429.
- Timeout: 15 s per attempt by default; raise
timeout(milliseconds) inconfig/attract.tsfor longer.
More examples
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/redirects_get_redirect.spec.ts, then run your tests:
tests/unit/redirects_get_redirect.spec.ts
Terminal
redirects.getRedirect with factories.Redirect({...}), the fields you give over a valid example.
tests/unit/redirects_get_redirect_answers.spec.ts
