Public delivery

Public delivery is the surface your frontend hits. It serves published content only, authenticates with a project-scoped API key (no JWT, no user session), and is safe to call from browsers and mobile apps.

GET https://api.sandbox.ovok.com/v1/public/cms/{typeSlug}/items?environment=dev&projectId={medplumProjectId}
GET https://api.sandbox.ovok.com/v1/public/cms/{typeSlug}/items/{idOrSlug}?environment=dev&projectId={medplumProjectId}

Required query parameters

Param	Required	Description
environment	Yes	dev, staging, or prod — selects the content partition
projectId	Yes	Medplum project UUID; resolves the Payload tenant

Use projectId, not projectSlug, on this surface.

Authentication

Send the API key as Authorization: Bearer …, x-api-key: …, or ?apiKey=…. Each key is bound to exactly one project when PAYLOAD_CMS_PUBLIC_API_KEY is configured on ovok-core (sandbox may allow unauthenticated access when that env var is unset).

Mint keys from the Console at Settings → API keys → CMS:

GET /v1/public/cms/pages/items?environment=dev&projectId=4897826b-4ff5-4ce4-a96a-849a40f51f60 HTTP/1.1
Host: api.sandbox.ovok.com
Authorization: Bearer cmspub_a4f3b21c...
Accept: application/json

How to mint a key →

:::tip Key safety API keys identify your project. They're meant to be shipped in your frontend bundle — they only grant read access to published content. But: rotate them on schedule, scope them per app, and never check them into a public repo. :::

List items in a collection

curl "https://api.sandbox.ovok.com/v1/public/cms/pages/items?environment=dev&projectId=$MEDPLUM_PROJECT_ID" \
  -H "Authorization: Bearer $OVOK_CMS_KEY"

Additional query params:

Param	Type	Description
limit	integer	Max items per page (default 10, max 100)
page	integer	1-indexed page number
sort	string	Sort field, prefix - to reverse (-publishedAt)
where[field][op]	JSON	Payload's standard filter syntax

Example — recent published blog posts, newest first:

curl "https://api.sandbox.ovok.com/v1/public/cms/posts/items?environment=dev&projectId=$MEDPLUM_PROJECT_ID&sort=-publishedAt&limit=5" \
  -H "Authorization: Bearer $OVOK_CMS_KEY"

Get one item

By ID:

curl "https://api.sandbox.ovok.com/v1/public/cms/pages/items/abc123?environment=dev&projectId=$MEDPLUM_PROJECT_ID" \
  -H "Authorization: Bearer $OVOK_CMS_KEY"

By slug (Payload's slug field, if your collection defines one):

curl "https://api.sandbox.ovok.com/v1/public/cms/pages/items/pricing?environment=dev&projectId=$MEDPLUM_PROJECT_ID" \
  -H "Authorization: Bearer $OVOK_CMS_KEY"

The endpoint resolves slug vs ID automatically. Drafts and unpublished items return 404 here regardless of whether you ask by ID or slug.

What's not returned

Public delivery hides the bits authors don't want public:

• Items with _status: draft or _status: published but publishedAt in the future
• Soft-deleted items
• Internal-only fields (anything marked admin.hidden in the Payload collection config)
• Items not in the key's project or wrong environment

If you can read an item via /v1/content/api/... but not via /v1/public/cms/.../items/..., check draft status, environment, and projectId first.

CORS

Public delivery is the only CMS surface with browser-friendly CORS. The proxy returns Access-Control-Allow-Origin: * for GET and HEAD. If you need a stricter origin set, terminate at your own edge (Vercel, Cloudflare) and lock CORS there.

Caching

Responses include Cache-Control: public, max-age=60, s-maxage=300 by default — a minute on the client, five minutes on shared caches. Publishing an item invalidates the shared cache for that item's collection via a fan-out hook. Custom cache headers per collection are on the roadmap.

Errors

Status	Meaning
401	API key missing or revoked
403	API key belongs to a project where CMS is disabled
404	Item doesn't exist, isn't published, or belongs to another project
429	Rate-limited — back off and retry
502	Tenant unreachable — retry
