Check connection readiness from a Slack DM

Find out whether the apps a request depends on are ready before it turns into another follow-up loop.

Trigger

Direct Message Received

Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.

Action

Check multiple active connections

Check active connection status for multiple toolkits or specific connected account ids. returns connection details if active, or required parameters for establishing connection if none exists. active connections enable agent actions on toolkits.

Why this helps

You begin a task only to discover that an app connection is missing, forcing a context switch and a restart.

  • Identify connection gaps at the start of a request.
  • Avoid retrying work against disconnected apps.
  • Give the requester a clear readiness update.

Setup

Build it in a few focused steps.

  • 1Connect Slack and Composio to Notis once in the portal.
  • 2Create an automation in the portal with a plain-language instruction to check relevant Composio connections when a DM requests cross-app work.
  • 3Select Slack Direct Message Received as the trigger and choose a channel for run reports.
  • 4Test by sending a real DM request that depends on a connected app.

Questions about this workflow

Does a connection check authorize an app?

No. It reports connection status. Complete any required authentication through the normal connection flow.

Can it inspect all DMs?

The Slack trigger catches direct messages across DM channels. It does not use channel messages.

Supported Triggers and Actions

Notis builds workflows that link Slack to Composio. A trigger fires from one place; an action lands in another.

Slack triggers

Composio actions

Recurring trigger

Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.

Ask Oracle

Static helper that returns a comprehensive system prompt describing how to plan and execute tasks using the available composio tools and workflows. no inputs required; simply call to retrieve the prompt. always call this after the search tool is executed -- it will provide the best context on how to proceed, chain tools, and execute the task end-to-end. relevant tools referenced by the prompt: 1. composio search tools 2. composio multi execute tool 3. composio execute code 4. composio manage connections 5. composio bash tool

Webhook trigger

Notis starts this workflow when an external tool or custom backend sends an HTTP request.

Check active connection (deprecated)

Deprecated: use check active connections instead for bulk operations. check active connection status for a toolkit or specific connected account id. returns connection details if active, or required parameters for establishing connection if none exists. active connections enable agent actions on the toolkit.

New Channel Created Trigger

Triggered when a new channel is created in Slack.

TriggerInstant

Check multiple active connections

Check active connection status for multiple toolkits or specific connected account ids. returns connection details if active, or required parameters for establishing connection if none exists. active connections enable agent actions on toolkits.

Channel Message Received

Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.

Create Plan

This is a workflow builder that ensures the LLM produces a complete, step-by-step plan for any use case. WHEN TO CALL: - Call this tool based on COMPOSIO_SEARCH_TOOLS output. If search tools response indicates create_plan should be called and the usecase is not easy, call it. - Use this tool after COMPOSIO_SEARCH_TOOLS or COMPOSIO_MANAGE_CONNECTIONS to generate an execution plan for the user's use case. - USE for medium or hard tasks — skip it for easy ones. - If the user switches to a new use case in the same chat and COMPOSIO_SEARCH_TOOLS again instructs you to call the planner, you MUST call this tool again for that new use case. Memory Integration: - You can choose to add the memory received from the search tool into the known_fields parameter of the plan function to enhance planning with discovered relationships and information. Outputs a complete plan with sections such as "workflow_steps", "complexity_assessment", "decision_matrix", "failure_handling" "output_format", and more as needed. If you skip this step for non-easy tasks, workflows will likely be incomplete, or fail during execution for complex tasks. Calling it guarantees reliable, accurate, and end-to-end workflows aligned with the available tools and connections.

Message Reaction Added

Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.

TriggerInstant

Execute agent

Execute complex workflows using ai agent reasoning between multiple tool calls. use this for: complex multi-step workflows requiring reasoning, error handling and retry logic. use composio multi execute tool instead for: simple parallel operations, batch operations on similar data (e.g., fetch 5 emails, get 10 sent messages, retrieve multiple user profiles), independent tool calls that don't need each other's results, or bulk operations where all parameters are known upfront. performance: agent calls add ~2-3 seconds overhead. use for workflows >3 tools or requiring conditional logic. avoid for simple parameter passing.

ActionInstant

Message Reaction Removed

Triggered when a reaction is removed from a message in Slack. Supports optional filtering by channel and emoji name.

TriggerInstant

Execute Composio Tool

Execute a tool using the composio api.

Reaction Added Trigger

DEPRECATED: use `SLACK_MESSAGE_REACTION_ADDED` instead. Triggered when a reaction is added to a message in Slack.

TriggerInstant

Get Tool Dependency Graph

Get the dependency graph for a given tool, showing related parent tools that might be useful. this action calls the composio labs dependency graph api to retrieve tools that are commonly used together with or before the specified tool. this helps discover related tools and understand common workflows.
