# Domains and TLS
URL: https://openship.io/docs/api/domains.md

Attach hostnames, verify DNS, and manage certificates.

import { TypeTable } from 'fumadocs-ui/components/type-table';

Domains connect hostnames to a project and track DNS verification and TLS certificates. The SDK takes a
project ID as the first argument when creating or listing domains; REST includes it in the body or query.

## Add a domain

<Callout title="Adding a domain doesn't make it live by itself" type="info">
After adding, you must point your DNS at Openship and then **verify**. Use `POST /api/domains/preview`
(or `openship domain preview <hostname>`) to see the exact records to add at your DNS provider first.
</Callout>

## Preview required DNS

Side-effect-free: pass a hostname, get back the records to create. `POST` is used only so the hostname
travels in the body.

<Tab value="SDK">

```ts
const result = await ship.domains.preview({
  hostname: "app.example.com",

The response's `mode` tells you which setup applies: `selfhosted` (an A record to your server), `cloud`
(a CNAME to Openship Cloud), or `external` (a TXT record only — you front TLS yourself).

## Verify a domain

<Tabs items={['SDK', 'REST API']} groupId="api-transport" persist>
<Tab value="SDK">

```ts
const verification = await ship.domains.verify("dom_123");
console.log(verification);
```

</Tab>
<Tab value="REST API">

```bash
curl -X POST "$OPENSHIP_URL/api/domains/dom_123/verify" \
  -H "Authorization: Bearer $OPENSHIP_TOKEN"
```

</Tab>

Once DNS is in place, verify it. Openship Cloud checks its routing and ownership records. Self-hosted
verification obtains or reuses the certificate on the deployment server. Domains with external ingress
keep TLS at their upstream proxy.

## Wildcard HTTPS and manual TXT

Wildcard and DNS-01 domains on self-hosted targets use the same operations in the dashboard, SDK and MCP.
Deploy and enable the project first. An external ingress or uploaded certificate keeps its existing TLS flow.

```ts
// "automatic" uses a connected DNS provider. "manual" generates a real ACME TXT.
const attempt = await ship.domains.startDnsChallenge("dom_123", { mode: "manual" });
const current = await ship.domains.dnsChallenge("dom_123");
// Once current.status is "waiting", publish current.record at the DNS provider.
// Then explicitly ask Openship to check it:
await ship.domains.checkDnsChallenge("dom_123", { attemptId: attempt.id });
```

Start and check return **202** with `{ data: attempt }`; they do not hold the HTTP request open for
certificate issuance. Read `GET /api/domains/:id/dns/challenge` until the result settles. It returns
`{ data: null }` before any attempt. The safe attempt includes `id`, `domainId`, `mode`, `status`,
`record`, `expiresAt`, `logs`, `error`, `createdAt` and `updatedAt`. It never includes private keys,
account credentials or serialized ACME orders.

`preparing`, `checking`, `installing` and `cancelling` represent running work. `waiting` needs the operator's
TXT; stop polling until they act. `completed`, `failed`, `cancelled` and `expired` are settled results.
A missing TXT or retryable validation/install error keeps the same order in `waiting` with its error.
Repeated starts reuse an active attempt; check and cancel require its current `attemptId` and reject
a stale ID with **409**. An installation that has already started cannot be cancelled.

Manual renewal uses `startDnsChallenge(id, { mode: "manual", force: true })` and a fresh TXT value.
`cancelDnsChallenge(id, { attemptId })` discards an unfinished manual attempt without removing existing TLS.
Connected-provider mode renews automatically when the SSL job is enabled. See the
[wildcard guide](/docs/guides/custom-domains#wildcard-domains) for DNS names, record cleanup and renewal steps.

## Errors

<Callout title="422 — verification failed" type="warn">
The DNS records aren't resolving yet, or don't match. DNS can take minutes to hours to propagate. Confirm
the records match `preview` exactly, then retry. The response's `cnameVerified` / `txtVerified` flags tell
you which check is still failing.
</Callout>

<Callout title="404 on a per-domain route" type="error">
The `:id` doesn't belong to your organization (or was deleted). List your domains with `GET /api/domains`
to get valid IDs.
</Callout>
