Example Use Cases
These are example ways Snow can use Ably when building apps with you. This list is meant to show examples, not document every possible capability. Connecting an account does not make Snow run these automatically on its own.
Tool to batch publish messages to multiple channels in parallel. Use when you need to send the same set of messages to multiple channels simultaneously for efficient broadcasting.
Tool to batch publish push notifications directly to specific recipients. Use when you need to send multiple push notifications efficiently in a single request. Supports up to 10,000 notifications per batch.
This tool allows you to unsubscribe devices or clients from push notifications for specific channels. The operation is asynchronous, so immediate requests after deletion may briefly still return the subscription.
This tool retrieves the current server time from Ably's service in milliseconds since the epoch. It is particularly useful for time synchronization and generating valid TokenRequest timestamps to prevent replay attacks. The endpoint supports multiple content types, handles HTTP errors, network issues, and is a fundamental tool for ensuring accurate timing in Ably applications.
This tool retrieves your application's usage statistics from Ably. The stats endpoint returns a paginated list of your application's usage statistics by minute, hour, day, or month. It supports optional parameters such as start, end, direction, limit, and unit to filter and format the returned data. The stats include metrics for: - Message counts and data transferred - Connection counts - Channel usage - API request counts - Push notification metrics - Token request counts
This tool retrieves metadata and details for a specific channel in Ably. It returns a ChannelDetails object containing information about the channel's status, occupancy, and other metadata. The endpoint provides visibility into channel activity, including metrics such as connections, presence, publishers, and subscribers, and requires appropriate permissions.
This tool retrieves the message history for a specified Ably channel. It uses the GET /channels/{channelId}/messages endpoint to return a paginated list of messages in chronological order, subject to parameters such as 'channelId', 'limit', 'direction', 'start', and 'end'. The tool is useful for auditing, recovering missed messages, analyzing channel activity, and debugging message flows. Authentication is required via basic or token authentication.
Tool to obtain the set of members currently present for a channel. Use when you need to check which clients are currently connected and active on a specific Ably channel.
This tool retrieves the history of presence messages for a specified channel in Ably. It allows you to query presence events on a channel within a given time period.
Tool to retrieve all historical versions of a specific message from an Ably channel. Use when you need to track message history, including the original message and all subsequent updates or delete operations. Each version includes metadata such as timestamp, action type, and client ID.
