# List the articles this account liked **GET /liked-articles** The articles this person liked, most recently liked first. The same page as `GET /saved-articles`: the same gates, the same `?expand=article` gated the same way, the same silence when an entry is gated away. Read that operation for every rule this one also obeys. **A like is not a save.** A save is a private list a person keeps; a like is a signal they gave the newsletter, and the newsletter can read it. Do not treat the two as interchangeable. **This is the reader's half of a like, not the newsletter's.** The tally is `article.stats.likes`, which any credential reads. Who is behind it is readable by the newsletter the like was aimed at, as engagement records on `GET /newsletters/{newsletter}/events?event_type=like` and as the `article.liked` topic. This operation is scoped to a person instead: one person's own likes across every newsletter they read. **Needs `account: read`**, which either an API key or an OAuth token can carry. ## Servers - Production. There is no separate sandbox host. : https://api.usecommune.com (Production. There is no separate sandbox host. ) ## Authentication methods - Api key - Oauth2 ## Parameters ### Headers - **Commune-Version** (string) 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 answers `400` with `invalid_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. ### Query parameters - **cursor** (string) The `pagination.next_cursor` value from the previous page. Omit it to read the first page. A cursor is opaque, is only valid for the same operation with the same filters, and is not a durable identifier. - **limit** (integer) How many items to return in this page. This is a page size, not an offset. Fewer items than requested may come back and that does not mean the collection is exhausted, only an absent `next_cursor` does. - **expand** (string) Comma-separated list of relationship paths to inline in the response. Unexpanded relationships are returned as a reference object carrying only `id` and `object`. Each operation documents the paths it accepts, and an unknown path answers `400`. Nested paths use a dot, for example `article.newsletter`. - **fields** (string) 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. `id` and `object` are always returned. An unknown property name answers `400`. Properties omitted by an operation, such as `content` on any article list, cannot be brought back with `fields`. ## Responses ### 200 A page of liked articles, most recently liked first. #### Body: application/json (object) - **object** (string) Always `list`, so a response is self describing. - **pagination** (object) Cursor pagination state. Commune never exposes an offset or a page number: a collection is a moving window, and an offset silently skips or repeats items when the window shifts between two requests. - **data** (array[object]) The articles this account liked, most recently liked first. Same gates as the saved list: an entry is present only while this person may still read the article, so a page can be shorter than the number of likes they left and an entry can disappear on its own. This is one person's own likes across every newsletter they read, never a roster of who liked one article. Each `article` is a reference unless `?expand=article` asks for the summary. ### 400 The request was malformed, and the same request will fail the same way until it is changed. `param` names the parameter or header at fault when there is exactly one, and `allowed_values` lists what it accepts when that is a finite set. The code is `bad_request` for 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 `expand` path or `fields` name, an identifier that is not a UUID), or a required one left out, such as `q` on a search or `newsletter` when 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. `param` is absent here, since the body is not a parameter, and the message names the property. * **The `Idempotency-Key` header**, 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. #### Body: application/json (object) - **error** (object) ### 401 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. #### Headers - **WWW-Authenticate** (string) The authentication scheme this API accepts, and where to find out how to get a credential for it. Always `Bearer realm="Commune API", resource_metadata="https://api.usecommune.com/.well-known/oauth-protected-resource"`. `resource_metadata` is the RFC 9728 pointer to this API's protected resource metadata, which names the authorization server an OAuth client should send its user to. A client holding an API key can ignore it. The header carries no `error` parameter, not even `error="invalid_token"`, because it describes what this API accepts rather than what was wrong with the credential sent, and the reasons above are deliberately indistinguishable. There is no second scheme and no query-parameter fallback, because a credential that can travel in a URL ends up in access logs and referer headers. #### Body: application/json (object) - **error** (object) ### 403 The credential is valid but is not allowed to do this. Two codes answer with this status, and `error.code` says which. **`insufficient_scope`: it does not hold the permission.** The operation needs, say, `audience: read` on the newsletter addressed, and this credential holds less than that there. `allowed_values` carries 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 `read` permissions may not use, or an `expand` path whose rows need a permission the operation does not. `param` names the parameter, and `allowed_values` carries 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; `param` is `newsletter`, and `GET /newsletters` lists the ones it does reach. Or, on `DELETE /api-keys/{key}`, the credential named belongs to somebody else. Neither carries `allowed_values`, because there is no value to send instead. #### Body: application/json (object) - **error** (object) ### 429 Too many requests. Back off and retry after the interval named by the `Retry-After` response header. One of the budgets in `RateLimit-Policy` ran out, and the `RateLimit-*` headers on this response say which and when it resets. #### Headers - **Retry-After** (integer) Seconds to wait before retrying. #### Body: application/json (object) - **error** (object) ### 500 Something failed inside Commune. The request may be retried. #### Body: application/json (object) - **error** (object) [Powered by Bump.sh](https://bump.sh)
