  3. Scheduled messages (3/4): State Layer API #4358 State Layer API
  4. Scheduled messages (4/4): Scheduled Messages Demo App #4365 Scheduled Messages Demo App

🎯 Goal

Generate the OpenAPI models and endpoints of scheduled messages, so the next PRs can build the SDK support on them.

📝 Summary

  • Endpoints: queryScheduledMessages, updateScheduledMessage, sendScheduledMessageNow and deleteScheduledMessage.
  • SendMessageRequest.scheduledAt, and SendMessageResponsePayload.scheduledMessage in its response.
  • includeScheduledMessages on ChannelGetOrCreateRequest and QueryChannelsRequest, with ChannelStateResponse.scheduledMessages.
  • The schedule-message channel capability.
  • The ScheduledMessageServerStatus, ScheduledMessageQueryStatus and ScheduledMessageFailureReason enums of the status, the status filter and the failure reason.

🛠 Implementation

  • Generated with Scripts/openapi_generate.sh. The properties the SDK does not read are removed in the "Unread by the SDK" block. The generated ScheduledMessageStatus is renamed to ScheduledMessageServerStatus, since ScheduledMessageStatus is the SDK's status that merges the local and server states.
  • The offline queue does not queue the new endpoints, so its switch over the generated endpoints stays exhaustive.
  • The scheduled_message.* events are generated in the next PR, because turning them into domain events needs the ScheduledMessage model.
  • No behavior change: nothing calls the new endpoints yet.

🧪 Manual Testing Notes

Nothing to test manually. It builds, and the existing tests pass.

☑️ Contributor Checklist

  • I have signed the Stream CLA (required)
  • This change should be manually QAed
  • Changelog is updated with client-facing changes
  • Changelog is updated with new localization keys
  • New code is covered by unit tests
  • Documentation has been updated in the docs-content repo

Summary by CodeRabbit

  • New Features
    • API support now includes scheduled-message operations and their associated request and response types.
  • Behavior Changes
    • Deleting, querying, sending immediately, or updating a scheduled message while offline will no longer queue the action for later; these actions require a network connection.
  • API Changes
    • OpenAPI definitions no longer include html, mml, or sharedLocation in scheduled-message content, cooldownRemainingMs in channel state, or includeActiveMemberCount in channel queries.

Add the scheduled messages endpoints and models from the backend spec, with the include_scheduled_messages option of the channel queries and the scheduled_at of SendMessage.

Walkthrough

The OpenAPI generation rules now retain scheduled-message endpoints and models, classify request and response models, and remove selected properties. Four scheduled-message endpoints are excluded from offline queuing. The SDK Size workflow now specifies four pull request activity types.

Changes: Scheduled Message API Support

Layer / File(s) Summary
Retain scheduled-message endpoints and models
Scripts/openapi_generate.sh
The generation script includes scheduled-message endpoints and models, and classifies request and response models by encoding direction.
Adjust generated model names and properties
Scripts/openapi_generate.sh
The script renames the generated status model to ScheduledMessageServerStatus and removes selected properties from generated request and response models.
Exclude scheduled-message endpoints from offline queuing
Sources/StreamChat/APIClient/Endpoints/EndpointPath+OfflineRequest.swift
The delete, query, send-now, and update scheduled-message endpoint paths return false from shouldBeQueuedOffline.

SDK Size Workflow

Layer / File(s) Summary
Set pull request activity types
.github/workflows/sdk-size-metrics.yml
The workflow’s pull request trigger now runs for opened, synchronize, reopened, and ready_for_review events.

Scheduled messages containing shared locations may lose that content when decoded; retain the location payload before merging.

Interesting that these (failureReason and status) are not defined as enum in the backend. Followed up on Slack.

LGTM

The job is skipped for draft PRs, and a PR marked as ready for review had no run until its next push.
The backend now names the status, query status and failure reason enums of the scheduled messages. The status is generated as ScheduledMessageServerStatus, since ScheduledMessageStatus is the SDK's merged status.

Retain sharedLocation for scheduled-message content.

ScheduledMessageContentResponse is a decoded API model. The API schema includes shared_location with a dedicated ScheduledMessageLocation payload. This removal silently drops location data from scheduled messages that contain it. Keep sharedLocation and retain/classify ScheduledMessageLocation. (raw.githubusercontent.com)
