Connect

Connect Codex to any app using the Composio CLI. Stop generating text about what you could do - actually do it from the shell.

When to Use This Skill

Use this skill when you need Codex to:
  • Send that email instead of drafting it
  • Create that issue instead of describing it
  • Post that message instead of suggesting it
  • Update that database instead of explaining how

What Changes

Without ConnectWith Connect
"Here's a draft email..."Sends the email
"You should create an issue..."Creates the issue
"Post this to Slack..."Posts it
"Add this to Notion..."Adds it

Supported Apps

1000+ integrations including:
  • Email: Gmail, Outlook, SendGrid
  • Chat: Slack, Discord, Teams, Telegram
  • Dev: GitHub, GitLab, Jira, Linear
  • Docs: Notion, Google Docs, Confluence
  • Data: Sheets, Airtable, PostgreSQL
  • CRM: HubSpot, Salesforce, Pipedrive
  • Storage: Drive, Dropbox, S3
  • Social: Twitter, LinkedIn, Reddit

Setup

1. Install the Composio CLI

bash
curl -fsSL https://composio.dev/install | bash

2. Log In

bash
composio login
composio whoami
This opens a browser for authentication and lets you pick your default org and project. Use 
-y
to skip prompts in automated flows.

3. Link the Toolkits You Need

bash
composio link github
composio link gmail
composio link slack
Each command walks through OAuth once, then the connection persists.
Done. Codex can now drive any connected app from the shell.

Core Workflow

  1. Know the tool slug? → 
    composio execute
  2. Don't know the slug? → 
    composio search
  3. Need clarification on inputs? → 
    composio execute --get-schema
    or 
    --dry-run
  4. Toolkit not connected? → 
    composio link <toolkit>
    and retry
  5. Multiple steps needed? → 
    composio run
    for workflows, 
    composio proxy
    for raw API calls

Examples

Discover a Tool

bash
composio search "create a github issue"
composio search "send an email" --toolkits gmail

Inspect Inputs Before Calling

bash
composio tools info GITHUB_CREATE_ISSUE
composio execute GITHUB_CREATE_ISSUE --get-schema
composio execute GITHUB_CREATE_ISSUE --dry-run -d '{"owner":"acme","repo":"app","title":"Bug"}'

Send an Email

bash
composio execute GMAIL_SEND_EMAIL -d '{
  "recipient_email": "sarah@acme.com",
  "subject": "Shipped!",
  "body": "v2.0 is live, let me know if issues"
}'

Create a GitHub Issue

bash
composio execute GITHUB_CREATE_ISSUE -d '{
  "owner": "my-org",
  "repo": "repo",
  "title": "Mobile timeout bug",
  "labels": ["bug"]
}'

Post to Slack

bash
composio execute SLACK_SEND_MESSAGE -d '{
  "channel": "engineering",
  "text": "Deploy complete - v2.4.0 live"
}'

Run Calls in Parallel

bash
composio execute --parallel \
  GMAIL_FETCH_EMAILS -d '{"max_results": 2}' \
  GITHUB_GET_THE_AUTHENTICATED_USER -d '{}'

Chain Actions with 
composio run

bash
composio run '
  const issues = await search("github issues labeled bug this week");
  const summary = issues.map(i => `- ${i.title}`).join("\n");
  await execute("SLACK_SEND_MESSAGE", {
    channel: "bugs",
    text: `This week’s bugs:\n${summary}`
  });
'
Load reusable workflows from a file:
bash
composio run --file ./workflow.ts -- --repo composiohq/composio

Raw API Access (
proxy
)

When no dedicated tool exists, hit the authenticated API directly:
bash
composio proxy https://gmail.googleapis.com/gmail/v1/users/me/profile \
  --toolkit gmail

composio proxy https://gmail.googleapis.com/gmail/v1/users/me/drafts \
  --toolkit gmail -X POST -H 'content-type: application/json' \
  -d '{"message":{"raw":"..."}}'

How It Works

  1. You ask Codex to do something
  2. Codex picks a slug via 
    composio search
    or prior knowledge
  3. CLI checks connection, prompts 
    composio link
    if missing
  4. Action executes against the real API and returns JSON to stdout

Configuration

Global flags:
  • --log-level <all|trace|debug|info|warning|error|fatal|none>
  • --help
    for per-command docs
Environment variables:
  • COMPOSIO_API_KEY
    - auth credential (set for non-interactive use)
  • COMPOSIO_BASE_URL
    - custom API endpoint
  • COMPOSIO_SESSION_DIR
    - override artifact storage
  • COMPOSIO_DISABLE_TELEMETRY=true
    - opt out of telemetry

Type-Safe SDK (Optional)

Generate typed client code when you want to call tools from an app rather than the shell:
bash
composio generate ts    # TypeScript types
composio generate py    # Python types
Flags: 
-o <dir>
, 
--toolkits <list>
, 
--compact
, 
--transpiled
, 
--type-tools
.

Troubleshooting

  • Not logged in
     → run 
    composio login
  • Connection required for <toolkit>
     → run 
    composio link <toolkit>
  • Unknown slug → 
    composio search "<what you want>"
    or 
    composio tools list <toolkit>
  • Bad inputs → 
    composio execute <SLUG> --get-schema
    then 
    --dry-run
  • Action failed → check permissions in the target app
