Publish, subscribe, and act on realtime channel events at scale

CommunicationDeveloperAutomationCloud & InfrastructureMonitoring & Alerts

Ably is the realtime messaging infrastructure platform that powers pub/sub channels, presence, message history, and push notifications at global scale. Connect it to Actionist and your agents can publish structured events to any channel within about a minute of a trigger firing, retrieve message history for audits and incident post-mortems, query which clients are currently online, push device notifications when users are offline, and monitor application-wide usage statistics — all without a custom WebSocket server or bespoke notification backend.

Deployment signals reach every subscriber within a minute of release

When a new release tag is pushed to GitHub, the agent publishes a structured deployment event to the Ably ops channel so all subscribed monitoring clients update within about a minute, pushes a notification to on-call devices via push-admin, posts a summary to Slack, and logs the release in Notion — all before the first user notices the change.

    Agent attaches channel history as structured context to tickets

    When a high-severity ticket opens, the agent fetches session channel history and attaches it to the ticket — the escalation engineer sees the full event timeline without asking the customer to explain again.

  • Human Resources
    40 min / week
    Manual policy email blast

    HR composes and sends an email blast for every policy update, then manually tracks open rates to confirm acknowledgement — a 30-45 minute process per policy change.

    Human Resources Agent
    0 min
    Agent publishes policy updates to employee portals within a minute

    When a policy document is published, the agent broadcasts the update to the Ably HR channel and employee portals prompt a read-acknowledgement within about a minute — replacing the manual email blast.

  • Finance
    35 min / week
    Manual dashboard monitoring

    Finance leads manually check budget tracking spreadsheets multiple times per week to spot threshold breaches — delays of hours before the alert reaches the CFO.

    Finance Agent
    0 min
    Agent publishes live budget signals to finance dashboards automatically

    When a budget threshold is breached, the agent publishes the alert to the Ably finance channel and CFO's device within about a minute — no manual dashboard check required.

  • Operations
    75 min / week
    Manual channel and integration audit

    Ops manually visits the Ably dashboard to review active channels, checks integration logs for errors, and compiles the findings into a spreadsheet — a 60-90 minute process each week.

    Operations Agent
    0 min
    Agent audits active channels and integration health weekly

    The agent lists all active channels, checks that each integration target is reachable, and flags anomalies in the ops Slack channel — a full audit delivered before the Monday stand-up without any manual tool visits.

  • Legal
    20 min / week
    Manual access revocation

    Legal or IT manually tracks contractor offboarding dates, opens the Ably dashboard to revoke tokens, and records the action in a compliance spreadsheet — often delayed by hours or days.

    Legal Agent
    0 min
    Agent revokes tokens and logs the action automatically on offboarding

    When a contractor offboards, the agent immediately revokes their Ably tokens and logs the revocation with a timestamp to the compliance audit trail — evidence of timely access removal delivered automatically.

FAQs

Questions about Ably + Actionist

How does Actionist connect to Ably?
Go to the Apps tab, find Ably, and click Connect. The recommended path is an API key: navigate to your Ably dashboard, open your app, go to API Keys, copy the key (format: AppID.KeyID:secret), and paste it into Actionist's API key field. Actionist runs a test call to GET /time to confirm the handshake before any agent actions run.
What Ably API key capabilities does the agent need?
For publishing messages and managing channels the agent needs an API key with the 'publish' and 'history' capabilities enabled on the relevant channel namespaces. For presence operations it needs 'presence'. For push-notification admin operations (registering devices, publishing to device targets) it needs the 'push-admin' capability. You configure capabilities per-key in the Ably dashboard under API Keys — scope them to the channel namespaces the agent will use rather than granting a wildcard key.
Can I connect Ably to other apps in the same Actionist workflow?
Yes. Ably integrates naturally with monitoring, alerting, and data-pipeline tools. Common combinations: publish events from a database change trigger (Postgres, Supabase) to an Ably channel so connected clients update within about a minute; forward Ably channel messages to Slack or a webhook for team notifications; pull message history into Google Sheets for audit logging; or use Ably's queue rules to fan out channel messages to external systems like RabbitMQ or Amazon Kinesis — all orchestrated by the agent without custom server code.
What are the most common things agents do with Ably?
The four patterns that come up most often: (1) fanout alerting — publishing a message to a channel whenever a critical event occurs in another system (threshold breach, deployment, incident); (2) presence monitoring — querying which clients are currently connected to a channel to know if an agent, device, or user is online; (3) message history audit — retrieving the last N messages from a channel to reconstruct what happened during an outage or compliance review; (4) push notification dispatch — using push-admin to push device notifications when a channel event should reach users even when the app is in the background.
How far back can the agent retrieve Ably message history?
Ably retains channel message history for up to 72 hours depending on the persistence setting configured for that channel namespace (persistence must be enabled in the channel rule in your Ably dashboard). The agent uses the Get Channel History action to retrieve messages with optional direction (forwards/backwards), limit (up to 1,000 per call), and time-range parameters. For longer-term retention you should forward messages to an external store (Google Sheets, a database) via the agent or Ably's queue/webhook integrations.
Can the agent publish messages to Ably channels from other app events?
Yes. Actionist's agent can call the Publish Message to Channel action to broadcast a message to any Ably channel — that message is delivered to all currently subscribed clients within about a minute. You can publish from any trigger: a schedule, a webhook, a database change, or an event from another app. The message payload is a JSON object you compose in the agent step, so you can include any structured data your subscribers need.
How do Ably channel namespaces affect how I use the agent?
Ably channel namespaces let you apply rules — persistence, push-notification routing, access control — to all channels that share a prefix (e.g. 'alerts:*'). In Actionist you don't manage namespace rules through the agent (that's a dashboard configuration task); instead, you design your channel naming scheme before connecting, then target channels by name in the agent's actions. If your channels follow a naming convention like 'team:engineering:deploys', the agent can dynamically construct the channel name from upstream data and publish or subscribe to the right channel without hardcoding.
What is the difference between publishing to a channel and using Ably push-admin?
Ably Push Admin lets the agent push notifications to registered mobile devices and browsers even when those clients are not connected to an Ably channel. The workflow is: devices register a push token with Ably (via the Ably SDK in your mobile app), subscribe to a channel or a device target, then the agent calls Publish Push Notification via Admin to dispatch a notification to that target. This is distinct from channel pub/sub — the notification goes to the device's OS notification system, not to an open WebSocket connection. You need the 'push-admin' capability on your API key.
