Headers

• Commune-Version string(date)

  The contract version this request is written against, as a release date (YYYY-MM-DD). 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. An unknown value answers 400 with invalid_version.

Path parameters

• sender string(uuid) Required

  The sending address's id. It has no short id.

Query parameters

• 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.

  One accepted path is not a relationship. ?expand=content on GET /articles/{article} adds the Markdown rendition of the body beside the HTML one. It is the same trade the parameter always offers, a fuller response for a larger one, over a property that has more than one representation rather than over a reference.

• 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.

  A trimmed body is a subset of the schema this operation declares, and a property that schema marks required is absent when it was not asked for. That is the point of the parameter, so a client that validates responses against the schema either sends no fields or relaxes required.

        Cover image. When the creator set none, Commune stamps the first image in the body at send time, so this is usually populated for a sent issue.

      • external_url string(uri) | null

        The issue's canonical URL on the newsletter's own provider, for an imported article. Null for a natively published one.

      • status string Required

        Where an issue is in its life. Only sent is ever visible to a public key. An imported article is always sent, since Commune sees it after the provider delivered it.

  • verification_status string Required

    How far along the address is. Only verified can send. provisioning means Commune is still setting it up and the creator has nothing to do yet.

    Values are provisioning, pending, verified, or failed.

  • verification_records array[object]

    Hide verification_records attributes Show verification_records attributes object

    A record the creator has to publish in their own DNS before Commune can send from an address or serve a domain. These are public by nature: they end up in a zone anyone can query.

    • type string Required

      The record type.

    • name string Required

      The host the record goes on.

    • value string Required

    • priority integer | null

  • verification_error string | null

  • is_default boolean Required

  • verified_at string(date-time) | null

    When the address was first verified. Null if it never was.

  • last_checked_at string(date-time) | null

    When Commune last looked at the DNS. Verification is re checked on a schedule, so this moves without the creator doing anything.

  • created_at string(date-time) Required

    When the address was added.

  • updated_at string(date-time)

    When the row last changed.

• 400 application/json

    • code string Required

      The stable, machine readable reason a request failed. New codes may be added in a minor version, so treat an unrecognised code as a generic failure of its HTTP status class.

      Values are bad_request, invalid_version, unauthorized, forbidden, insufficient_scope, payment_required, not_found, conflict, unprocessable, rate_limited, or internal_error.

    • message string Required

      A human readable sentence describing what went wrong. Written for a developer reading a log, not for an end user. Do not branch on it, branch on code.

    • param string

      The query, path or body parameter the error is attributed to, when the error is attributable to exactly one. Absent otherwise.

    • allowed_values array[string]

      Everything param would have accepted, when what it accepts is a finite set. Absent when it is not: a cursor, an identifier or a numeric range has nothing to enumerate, and an empty array would read as "nothing is allowed".

      It is deliberately redundant with message, which names the same values in prose. The array is what a program branches on and the sentence is what a model reads, and a caller correcting a request has to be able to do it from this one response without opening a reference page.

      On an unknown parameter name rather than an unknown value, this carries the parameter names the operation does accept, since that is the set the caller has to pick from.

      On an insufficient_scope failure there is no parameter at fault and param is absent, and this carries the scopes that would have been accepted instead.

    • request_id string

      Identifier for this request, echoed in the Commune-Request-Id response header. Quote it in support requests.

    • docs_url string(uri)

      Link to the reference page for this error code.

• 401 application/json

  No API key was presented, or the key is unknown, revoked or expired.

  All four answer identically, down to the wording. Saying that a key was revoked rather than never issued confirms to whoever is holding the string that it was once real, which a legitimate caller does not need and a thief should not get.

      On an unknown parameter name rather than an unknown value, this carries the parameter names the operation does accept, since that is the set the caller has to pick from.

      On an insufficient_scope failure there is no parameter at fault and param is absent, and this carries the scopes that would have been accepted instead.

    • request_id string

      Identifier for this request, echoed in the Commune-Request-Id response header. Quote it in support requests.

    • docs_url string(uri)

      Link to the reference page for this error code.

• 403 application/json

  The key is valid but is not allowed to read this. Either it carries public scope and the operation needs creator scope, or it is bound to a different newsletter than the one addressed.

    • code string Required

      The stable, machine readable reason a request failed. New codes may be added in a minor version, so treat an unrecognised code as a generic failure of its HTTP status class.

      Values are bad_request, invalid_version, unauthorized, forbidden, insufficient_scope, payment_required, not_found, conflict, unprocessable, rate_limited, or internal_error.

    • message string Required

      A human readable sentence describing what went wrong. Written for a developer reading a log, not for an end user. Do not branch on it, branch on code.

    • param string

      The query, path or body parameter the error is attributed to, when the error is attributable to exactly one. Absent otherwise.

    • allowed_values array[string]

      Everything param would have accepted, when what it accepts is a finite set. Absent when it is not: a cursor, an identifier or a numeric range has nothing to enumerate, and an empty array would read as "nothing is allowed".

      It is deliberately redundant with message, which names the same values in prose. The array is what a program branches on and the sentence is what a model reads, and a caller correcting a request has to be able to do it from this one response without opening a reference page.

• 404 application/json

  No such resource, or the key is not allowed to know that it exists. Commune answers 404 rather than 403 where distinguishing the two would leak the existence of private content.
