List episodes

get

https://{subdomain}.supercast.com/api/v1/episodes

Lists the current channel's episodes, newest first by insertion order.

A channel must be in scope: use a channel token, or a network token plus
channel_subdomain.

Supplying user resolves a subscriber and populates each episode's audio_url with that
subscriber's personalised media URL. Without it, audio_url is null.

Required scope: public.

Query Params

channel_subdomain

string

Selects which channel or network the request acts on.

This applies to every endpoint in this API, not only GET /episodes. Its requirement
depends on what the access token's resource owner is:

Channel token — ignored. The token already identifies the channel.
Network token — optional. Omit it to act on the network itself; supply the subdomain
of one of the network's channels to act on that channel instead. An unrecognised subdomain
returns 400.
User or superapp token — required. The token is not bound to an entity, so the
target must be named on every request. Omitting it returns 400; naming an entity the user
does not manage returns 403.

The X-CHANNEL-SUBDOMAIN header takes precedence over this parameter. A legacy subdomain
query parameter is also still accepted as a fallback.

updated_since

date-time

Only return records updated at or after this time — an ISO 8601 timestamp.

The comparison is inclusive (>=), so a consumer polling for changes can pass the newest
updated_at it has already seen without missing records written in the same second. Expect
to see the boundary record returned again and deduplicate on id.

On endpoints whose payload is assembled from more than one table, the filter matches a change
to any of those tables — see the individual endpoint description for which.

A value that is not valid ISO 8601 returns 400. A blank value is treated as absent.

page

integer

≥ 1

Defaults to 1

1-based page number. Pagination metadata is returned in the Link, X-Total, X-Per-Page and X-Page response headers.

per_page

integer

≥ 1

Defaults to 30

Number of records per page.

sort

string

enum

Defaults to id

Column to order the page by. Ties are broken by id, so paging through the collection is stable and a record cannot appear on two pages or be skipped between them. A value outside the list falls back to the default rather than returning 400.

Allowed:

direction

string

enum

Direction to read sort in — asc or desc.

The default is per endpoint: it is whatever ordering that collection already returned before
it became sortable, and the endpoint's own sort parameter names it. Anything other than
asc or desc falls back to that default rather than returning 400.

It applies to the id tiebreaker as well as to sort, so reversing the direction reverses
the whole page rather than only its first key.

Allowed:

user

string

A subscriber's e-mail address or Supercast uuid. Used to personalise the response for that listener. When omitted or unresolvable, the per-viewer fields are returned empty rather than erroring.

Headers

X-CHANNEL-SUBDOMAIN

string

Header form of channel_subdomain, and the preferred one — it takes precedence over both the channel_subdomain and legacy subdomain query parameters. See channel_subdomain for when a value is required.

Responses

200A page of episodes.

400The request was malformed — a required body key was missing, or a supplied channel_subdomain did not resolve to an entity, or a filter parameter such as updated_since was not parseable.

401No access token was supplied, or the token is invalid, expired, or revoked. Also returned when the token lacks the scope the endpoint requires.

403The token is valid but not permitted to act here — the requesting user does not manage the named entity, or the caller's IP address is on the channel's block list.

404No record matched, or the record exists but does not belong to the entity in scope.

422No channel is in scope. This endpoint operates on a single podcast, so it requires either a channel access token or a network access token together with channel_subdomain.

500An unexpected error occurred. The failure is reported to Supercast automatically.
