Retrieve one article's performance Run in API Explorer
How one article did on both sides at once: what the email did, and what the community did with it afterwards. No email provider can return the right hand column, because the reading, highlighting and arguing happened on Commune.
email is present only for an article Commune sent itself. For an article
imported from an outside provider it is null, because that provider
mailed it and never handed Commune the per recipient outcome. It is
null for an article that has not been sent yet as well.
community is computed at read time and keeps counting long after the
send, so two reads a week apart legitimately disagree.
Needs insights: read. The public tallies on an article, likes,
comments and highlights, live on the article itself and need only
content: read.
Which articles a key can measure depends on whether it acts for the
newsletter, which a key does when it holds write in any family. Such a
key can measure any of the newsletter's articles, including a draft or
one scheduled for later. A key that holds only read permissions can
measure exactly the articles getArticle would return to it: sent,
already published and not restricted to a tag. Any other article
answers 404, the same answer as an id that does not exist, so this
operation never confirms that an unpublished article exists. For an
article both kinds of key can read, the numbers are the same.
Headers
-
The contract version this request is written against. Every version published so far is a release date (
YYYY-MM-DD), which is why the examples look like one, but the value is an opaque identifier: match it against the versions this API publishes rather than parsing it, because a future one may not be only a date. An unknown value answers400withinvalid_version.Omitting the header pins the request to the version that was current when the API key was issued, so an integration keeps working when a newer version ships.
Minimum length is
1.
Path parameters
-
The article's
id(a UUID) or itsshort_id, an eight character base62 string that is unique across Commune. Theslugis not accepted here because it is unique only within a newsletter.
Query parameters
-
Comma-separated list of relationship paths to inline in the response. Unexpanded relationships are returned as a reference object carrying only
idandobject. Each operation documents the paths it accepts, and an unknown path answers400. Nested paths use a dot, for examplearticle.newsletter. -
Comma-separated allow-list of top level properties to return on each object, so a client can trim a response it does not need in full.
idandobjectare always returned. An unknown property name answers400. Properties omitted by an operation, such ascontenton any article list, cannot be brought back withfields.

The request was malformed, and the same request will fail the same way until it is changed.
paramnames the parameter or header at fault when there is exactly one, andallowed_valueslists what it accepts when that is a finite set. The code isbad_requestfor every case below except the last.- A query parameter: one the operation does not have, a value
outside its set, range or format (an unparseable cursor, an unknown
expandpath orfieldsname, an identifier that is not a UUID), or a required one left out, such asqon a search ornewsletterwhen the credential reaches more than one. - The request body: not JSON, not the shape the operation reads,
a property it does not write, or a value of the wrong type, length
or format.
paramis absent here, since the body is not a parameter, and the message names the property. - The
Idempotency-Keyheader, on an operation that changes something: missing, or a value this API will not store. - An unrecognised
Commune-Version, which answers with its own code,invalid_version, because it is never fixed by changing the body.
- A query parameter: one the operation does not have, a value
outside its set, range or format (an unparseable cursor, an unknown
-
No credential was presented, or it is malformed, unknown, revoked or expired, or it is an access token minted for a different audience.
Every one of these answers identically, down to the wording and the headers, so a refusal never confirms that a string was once real.
-
The credential is valid but is not allowed to do this. Two codes answer with this status, and
error.codesays which.insufficient_scope: it does not hold the permission. The operation needs, say,audience: readon the newsletter addressed, and this credential holds less than that there.allowed_valuescarries the permission that was needed, and the message says what the credential does hold on that newsletter, because a credential granted the wrong family and a credential belonging to somebody whose standing on the team has narrowed look identical without it. The answer can differ per newsletter: the same credential may be allowed here and refused on the next one it reaches.The same code answers an operation that needs the account permission from a credential that does not carry it. That permission is about the person a credential belongs to rather than about any newsletter, so nothing granted on a newsletter adds up to it. It is granted on the credential itself, when a key is minted or when an authorization asks for
account:read.And it answers a parameter the credential may send, but not with the value it sent: a filter a credential holding only
readpermissions may not use, or anexpandpath whose rows need a permission the operation does not.paramnames the parameter, andallowed_valuescarries what this credential may send instead, or is absent when it may send nothing there at all.forbidden: it may not act here at all. Either the credential does not reach the newsletter addressed, because it was never granted it or because the person it belongs to can no longer act on it, or it reaches no newsletter at all;paramisnewsletter, andGET /newsletterslists the ones it does reach. Or, onDELETE /api-keys/{key}, the credential named belongs to somebody else. Neither carriesallowed_values, because there is no value to send instead. -
No such resource, or the key is not allowed to know that it exists. Commune answers
404rather than403where distinguishing the two would leak the existence of private content. -
Too many requests. Back off and retry after the interval named by the
Retry-Afterresponse header.One of the budgets in
RateLimit-Policyran out, and theRateLimit-*headers on this response say which and when it resets. -
Something failed inside Commune. The request may be retried.
