TLDR

This PR adds Chat scheduled messages to the SDK. send_message (on both the client and Channel) now takes scheduled_at. When it is set, the message is not posted to the channel; the response carries scheduled_message instead. Four new chat methods manage pending scheduled messages: query_scheduled_messages, update_scheduled_message, send_scheduled_message_now and delete_scheduled_message.

The change is a plain regeneration from the backend spec plus one integration test. This SDK was behind chat master, so the regeneration also brings in other API changes, listed below. It includes a few small breaking changes, so the title uses feat!:, as earlier regenerations with removals did (#283). If the reviewer judges them non-breaking in practice, drop the !.

Risk: merge only after backend CHA-5924 is deployed. Older backends ignore scheduled_at and send the message immediately.

Ticket

Summary

Generated from chat master 39c07c8b1ce1a145a754e883721796c66467f313 (not yet a protocol release); merge after backend CHA-5924 is deployed — older backends ignore scheduled_at and send immediately.

How it was generated:

  • The spec came from make openapi in a chat worktree at that commit.
  • build/openapi generate-client --language python --spec releases/v2/serverside-api.yaml and generate-webhook-fixtures --time-format=unix-ns ran from the same tree, then ruff check --fix and ruff format ran with the locked ruff (UV_FROZEN=1). These are the same steps as generate.sh.
  • The generator emits Optional[X] / List[X], but the committed generated files use X | None / list[X] since feat: [CHA-4947] regenerate from latest OpenAPI #282 (CHA-4947). So I also ran ruff check --fix --select UP006,UP007,UP045,UP037 on the 17 generated files only. This keeps the existing style; without it the diff would include about 13k lines of annotation churn. No hand-written file was touched.

Scheduled messages (CHA-5924 backend: GetStream/chat#18596, #18597, #18655, #18656)

  • send_message(..., scheduled_at=...) on ChatRestClient and Channel, and SendMessageResponse.scheduled_message.
  • chat.query_scheduled_messages(user_id=..., filter=ScheduledMessagesFilter(cid=..., status=[...]), sort=..., limit=..., next=...). Server-side calls need user_id.
  • chat.update_scheduled_message(id, scheduled_at=None, message=None).
  • chat.send_scheduled_message_now(id).
  • chat.delete_scheduled_message(id).
  • ChannelStateResponse.scheduled_messages, the ScheduledMessage* models, and the scheduled_message.sent / scheduled_message.failed webhook events (now parsed by getstream.webhook).

The feature is off by default for each app; Stream enables it. The new tests/test_chat_scheduled_messages.py (marked integration) schedules a message, then queries, updates, sends now and deletes it. Each test skips itself in two cases: the app returns error 114 (feature disabled), or the backend ignores scheduled_at. I ran it locally against a chat master server with the feature on, and all 4 tests passed.

Unrelated changes picked up from chat master

Breaking:

  • AIVideoConfig.provider was removed.
  • ChannelMemberResponse.user_id and OwnUserResponse.blocked_user_ids are now required. The server always sent them, but code that builds these dataclasses without them now fails.
  • New optional keyword arguments are inserted in alphabetical order, as the generator always does. Callers that pass optional arguments by position may shift, for example scheduled_at now sits between pending and skip_enrich_url in send_message.

Additive:

  • Chat:
    • New: query_channel_bans (client and Channel) and its ChannelBan* models.
    • New arguments: sort on grouped_query_channels, synchronous on channel_batch_update, expires_at on create_reminder / update_reminder.
    • App and request defaults: AppDefaults, QueryChannelsDefaults, GetOrCreateChannelDefaults.
  • Polls: config_key / config_team on poll writes, team on create_poll, user_id on get_poll_option, and the poll webhook events (poll.closed, poll.updated, poll.vote_*, …).
  • Common: check_gcp_pub_sub, and the import.success / import.error and export.label_results.* webhook events.
  • Video:
    • New: query_call_ring_attempts, the call.ring_settled event and LifecycleSettings*.
    • New argument: custom on ring_call / Call.ring.
  • Feeds:
    • New endpoints: retention policy (feeds_get/set/delete_retention_policy, feeds_get_retention_policy_runs), user interests (upsert_user_interests / delete_user_interests), and comment_feedback with its event.
    • New arguments: skip_existing on add_activity / upsert_activities, _async on the batch follow/unfollow methods, include_group_counts on query_follows, discard_actors on get_or_create_feed, hard_delete on delete_collections, the include_* flags on get_activity / query_activities / query_comments / query_pinned_activities.
  • Moderation:
    • New: intent config (intent_config on upsert_config, IntentConfig*, IntentTopic*, IntentRuleParameters) and new rule parameter types.
    • New arguments: country_code on check / analyze, channel_cid on appeal, ban_from_future_channels / delete_reactions on ban, and the delete_poll* actions on submit_action.

Notes for review

  • Generated upload methods call _upload_multipart(..., json=json). That is a new generator output (GetStream/chat#17967), and it doesn't match BaseClient._upload_multipart(path, data_type, file_path, ...). The affected methods are upload_file, upload_image, upload_channel_file and upload_channel_image on the generated *RestClient classes. Users never reach these generated bodies: the hand-written CommonClient / AsyncCommonClient / ChatClient / AsyncChatClient override all four, and Stream, AsyncStream and Channel go through those overrides. Before this PR the generated bodies were self.post(..., json=json) and were shadowed the same way. The generator template should still be fixed in chat; that is out of scope here.
  • Positional-argument shifts (flagged by CodeRabbit): the generator always sorts optional arguments, and every earlier regeneration had the same effect. They are listed under Breaking above.
  • follow_batch(_async=...): the spec's FollowBatchRequest has an async field, but its own description says FollowBatch rejects it. That is a feeds spec issue, outside this PR.

Checklist

  • make lint passes
  • make typecheck gives the same 61 video/rtc diagnostics as main locally (local environment lacks the webrtc extras)
  • Unit lane pytest -m "not integration" passes: 495 passed
  • New integration test passes against chat master locally
  • CI green (integration tests run only in the daily job)

Note

Medium Risk
Large generated surface area with a few documented breaking model/positional-arg changes; scheduled messages and upload helper changes depend on correct backend deployment and hand-written client overrides remaining in place.

Overview
Regenerates the Python SDK from an updated OpenAPI spec, with scheduled messages as the headline capability: send_message accepts scheduled_at, and the client exposes query, update, send now, and delete for scheduled messages (plus related models and webhooks).

The regeneration also wires up channel ban queries (query_channel_bans on the REST client and Channel), extends chat (reminder expires_at, batch channel update synchronous, grouped channel query sort), polls (config_key / config_team, team), and common (GCP Pub/Sub check). Feeds gains retention-policy APIs, user-interest upsert/delete, comment feedback, and many new query/include flags; video ring accepts custom.

Across clients, build_query_param calls are refactored to pass explicit dicts (generator style), and generated file/image uploads now call _upload_multipart instead of post (still overridden by hand-written clients in practice). Webhook tests expand for new event types (scheduled messages, polls, imports, etc.).

Breaking (per PR): removed AIVideoConfig.provider; ChannelMemberResponse.user_id and OwnUserResponse.blocked_user_ids are required; optional kwargs are alphabetically reordered (positional callers to methods like send_message may break). Requires backend with scheduled-messages support deployed.

Merge Risk: 🟡 Moderate · up to 31895

This release adds scheduled messages and many new API options. As written, file and image uploads may fail outright, and one new follow option may be rejected by the server. Existing code that passes optional arguments by position can silently send the wrong values, for example a moderator ID being treated as a ban flag. Resolve the upload calls and confirm the positional-argument behavior before merging.

- Around line 1137-1139: Update all four upload calls to match the multipart
helper contract: pass the file as file_path and encode user data as form fields

- Around line 709-710: Restore positional compatibility by moving the newly
added configuration parameters after all pre-existing parameters in the poll
methods. In getstream/common/async_rest_client.py:709-710, 750-751, 836-837,

description continue to bind as before.

Review comments at @getstream/feeds/rest_client.py:
- Line 1469: In the public signatures of the REST client method and its wrapper,
move discard_actors after the existing parameters so data retains its original
positional index. Update both getstream/feeds/rest_client.py at line 1469 and
getstream/feeds/feeds.py at line 43; keep the option available without shifting
existing positional arguments.
- Line 2248: Remove the _async parameter and its request forwarding from
follow_batch because FollowBatchRequest does not support that option. Keep
_async available on get_or_create_follows.

Review comments at @getstream/moderation/async_rest_client.py:

clients: in getstream/moderation/async_rest_client.py at line 284, move the new

Generated upload methods pass wrong args to _upload_multipart

Medium Severity

The generated upload_channel_file, upload_channel_image, upload_file, and upload_image methods in ChatRestClient and CommonRestClient (sync and async) were changed from self.post(...) to self._upload_multipart(...), but the arguments don't match. _upload_multipart in base.py requires file_path as a positional third argument and does not accept a json keyword — yet the generated code omits file_path and passes json=json. This causes a TypeError at runtime. The ChatClient and CommonClient subclasses override these methods correctly, masking the issue for normal SDK usage, but the base class methods are now broken if called directly.

Verified: the generated *RestClient upload bodies call _upload_multipart(..., json=json), which doesn't match BaseClient._upload_multipart(path, data_type, file_path, *, ...), so calling them directly would raise TypeError. Users can't reach them, though. The hand-written ChatClient, AsyncChatClient, CommonClient and AsyncCommonClient override all four (upload_file, upload_image, upload_channel_file, upload_channel_image) with correct file_path + form_fields calls, and Stream / AsyncStream / Channel only go through those subclasses. Before this PR the generated bodies were self.post(..., json=json), which wasn't a working upload either and was shadowed the same way. This is new generator output from GetStream/chat#17967, so the fix belongs in the chat Python template, not in hand-edited generated files the next regen would overwrite. It's noted in the PR body under Notes for review.
