Blog Posts

Update a blog post

Update an existing blog post.

Access: an API key with content:blog:write (or a master above it: content:blog:all, content:all, admin:all). In published mode (the default) it goes live too, so the key also needs content:blog:publish (or a master above it); send aposMode=draft (or a draft _id and no aposMode) to 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.

Authorizations

Authorization

string

header

required

Paste your API key as the CMS showed it: fsk_<site>_<key id>_<secret> (issued under API Keys). ApiKey in front of it works too. Leave it empty to read as the public.

Scopes

content:blog:write

Path Parameters

_id

string

required

The document’s _id: a full id names its own locale and mode (the draft’s …:en:draft, the published one’s …:en:published; no aposMode needed), a bare aposDocId takes the request’s (aposLocale, aposMode).

Query Parameters

aposMode

enum<string>

default:published

published (the default) or draft. Drafts need a credential that may see them: an API key with the type’s write scope (content:<type>:write), or a signed-in editor. The public and a key with only the read scope get 403.

Available options:

draft,

published

aposLocale

string

The locale to read or write, e.g. en (default: the site’s default locale).

Example:

"fr"
