Get Channel History
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.
Why this helps
Catching up on a busy channel can mean scrolling through messages without knowing where to start.
- Retrieve message history when requested through a webhook.
- Ask Notis to summarize the returned messages for a focused catch-up.
- Use the action's history parameters to define the requested window where supported.
Setup
Build it in a few focused steps.
- 1Connect Ably once in Notis.
- 2Create an automation in plain language or in Automations, New Automation.
- 3In one instruction, describe the channel history to retrieve and how to summarize returned messages.
- 4Pick the Notis webhook trigger and choose where run reports go.
- 5Test with one real request for a channel with messages.

Create Ably Channel
Creates a new channel or retrieves an existing channel in ably. this tool allows you to programmatically create and initialize channels for real-time messaging. since ably creates channels implicitly when first used, this action publishes an empty initialization message to create/activate the channel.
Delete Channel Subscription
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.
Get Channel Details
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.
Get Channel History
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.
Get Channel Presence History
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.
Get Ably Service Time
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.
