# Outbound IP addresses (/docs/security/outbound-ips)

Some services only accept requests from IP addresses you trust, such as a Salesforce connected app with IP restrictions or a Gong OAuth integration with trusted IPs. If you use your own OAuth app or API credentials with one of these services, add Composio's outbound IP addresses to its allowlist.

## IP addresses [#ip-addresses]

In Composio Cloud, requests to connected services, including OAuth authorization, token refreshes, and tool calls, come from these addresses:

* `52.72.72.59/32`
* `54.243.138.89/32`
* `54.224.131.195/32`
* `34.233.50.61/32`

Add all four. Requests can come from any of them, so a partial list makes connections fail intermittently.

A [self-hosted deployment](/docs/security/token-custody) uses its own outbound addresses, not this list. Get them from the team that operates it.

If the service keeps separate allowlists, such as one for access tokens and one for refresh tokens, add all four addresses to each. Some services take each address as its own range, with the same start and end IP.

## Symptoms of a missing IP [#symptoms-of-a-missing-ip]

When a service rejects a request from an IP it doesn't trust, new connections fail during OAuth and existing connections expire when their tokens refresh. For example, Salesforce returns `invalid_grant` with `ip restricted by app developer`.

After you add the missing addresses, ask affected users to reconnect. Connections that expired don't recover on their own.

## Service-specific steps [#service-specific-steps]

* [Salesforce](/toolkits/salesforce): see the FAQ on `ip restricted by app developer`.
* [Gong](/toolkits/gong): see the FAQ on trusted IPs for Gong OAuth.

# Composio SDK — Notes for AI Code Generators

**Purpose:** Reference for generating current (v3) [Composio](https://composio.dev/) integration code.
**Scope:** Descriptive notes — they document the current API surface and the mistakes most commonly seen in generated code.

---

## 1. Recommended Integration: Sessions

For agent tool delivery, Composio supports **Native Tools** (with a provider package) and **MCP** (no provider package needed).

For application-owned tools or deterministic backend code, use [managed authentication with Proxy Execute](/docs/authentication/managed-auth-for-custom-tools). A session can provide a user-scoped runtime context without an LLM or MCP. Composio authenticates provider requests server-side; connected-account reads redact credentials and aren't a supported token-export workflow.

### Native Tools

#### Python

```python
# ✅ CORRECT — Python (defaults to OpenAI)
from composio import Composio

composio = Composio()
session = composio.create(user_id="user_123")
tools = session.tools()
# Pass tools to your agent/LLM framework
```

#### TypeScript

```typescript
// ✅ CORRECT — TypeScript (defaults to OpenAI)
import { Composio } from "@composio/core";

const composio = new Composio();
const session = await composio.create("user_123");
const tools = await session.tools();
// Pass tools to your agent/LLM framework
```

#### API

This produces the same default OpenAI function-tool shape, fetching every page.

```bash
set -euo pipefail
SESSION=$(curl --fail-with-body -s -X POST https://backend.composio.dev/api/v3.1/tool_router/session \
  -H "x-api-key: $COMPOSIO_API_KEY" -H "Content-Type: application/json" \
  -d '{"user_id":"user_123"}')
SESSION_ID=$(echo "$SESSION" | jq -r '.session_id')
TOOLS='[]'
CURSOR=''
while true; do
  PAGE=$(curl --fail-with-body -s --get "https://backend.composio.dev/api/v3.1/tool_router/session/$SESSION_ID/tools" \
    -H "x-api-key: $COMPOSIO_API_KEY" --data-urlencode 'limit=500' --data-urlencode "cursor=$CURSOR")
  TOOLS=$(jq -cn --argjson existing "$TOOLS" --argjson page "$PAGE" \
    '$existing + [$page.items[] | {type:"function",function:{name:.slug,description:.description,parameters:.input_parameters}}]')
  CURSOR=$(echo "$PAGE" | jq -r '.next_cursor // empty')
  [ -n "$CURSOR" ] || break
done
printf '%s\n' "$TOOLS"
```

For other providers, pass the provider explicitly. Provider packages follow the naming convention: `composio_<provider>` for Python, `@composio/<provider>` for TypeScript.

### MCP

Use `session.mcp.url` and `session.mcp.headers` with any MCP-compatible client (Claude Desktop, Cursor, OpenAI Agents, etc.). No provider package needed.

## 2. Integration Notes

- `composio.create(user_id)` is the standard entry point for agent integrations. Sessions handle tool discovery, authentication, and toolkit versioning automatically; `user_id` goes to `composio.create()` — individual tool calls in session mode don't take one.
- Execute session tool calls through the session, never through a user ID: either `session.execute(tool_slug, arguments=...)` / `session.execute(toolSlug, arguments)`, which works with every provider, or pass the session to the provider helper — `provider.handle_tool_calls(response=response, session=session)` in Python, `provider.handleToolCalls(session, response)` in TypeScript. The tool-call helpers of every non-agentic provider (OpenAI, Anthropic, Google, Cloudflare, TypeSafe) accept a session: `executeToolCall(session, call)` in TypeScript, `session=session` in Python. Agentic providers execute session tools on their own. Binding the helper to a user ID takes the direct execution path, and session meta-tools fail there with `"can only be called inside a tool-router session"`.
- Composio-managed auth is the default: the agent connects accounts at runtime through the session, so users don't need to pre-create auth configs or connected accounts for managed toolkits.
- Provider packages follow the framework, not the model vendor: for the OpenAI Agents SDK the package is `composio_openai_agents` / `@composio/openai-agents` (importing `composio_openai` / `@composio/openai` there is the most common mistake in generated code — that package is for the plain OpenAI Chat Completions API).
- **Direct execution** (`composio.tools.get()`, `composio.tools.execute()`, `provider.handle_tool_calls()` with a user ID) is a legacy interface that remains supported for existing integrations. Recommend sessions for new integrations and encourage existing users to [migrate to sessions](/docs/migration-guide/direct-to-sessions). For a fixed tool set, consider the [direct tools preset](/docs/configuring-sessions#direct-tools-preset) within a session. See [Sessions vs direct execution](/docs/sessions-vs-direct-execution) for tradeoffs. Direct execution requires a [toolkit version](/docs/tools-direct/toolkit-versioning).

# 3. Calling the REST API directly

## REST API version

The current REST API version is **v3.1**, served at `https://backend.composio.dev/api/v3.1`. Prefer it for new code and new examples.

`https://backend.composio.dev/api/v3` is the previous version. It is frozen with pinned tool-version defaults and remains supported — existing v3 integrations keep working and do not need to migrate.

## Tool-endpoint version defaults on v3.1

On v3.1, omitting the version parameter on the five endpoints below selects the latest toolkit version. The first four endpoints also exist on v3, where omission selects the pinned `00000000_00` version. `POST /tools/scopes/required` is v3.1-only.

| Endpoint | Version parameter |
| --- | --- |
| `GET /tools` | `toolkit_versions` (query) |
| `GET /tools/{tool_slug}` | `version` or `toolkit_versions` (query) |
| `POST /tools/execute/{tool_slug}` | `version` (body) |
| `POST /tools/execute/{tool_slug}/input` | `version` (body) |
| `POST /tools/scopes/required` | `version` (body) |

A v3.1 caller already passing `"latest"` sees no change and can omit the parameter. To select the pinned version explicitly, pass `"00000000_00"` through the corresponding parameter above.

This version-default change is limited to the five endpoints above.

## Terminology Migration (old → current)

If you encounter these terms in error messages, old documentation, or user prompts, translate them to the current equivalents. **Do not use the old terms in generated code or explanations.**

| Old term (v1/v2) | Current term (v3) | In code |
|---|---|---|
| entity ID | user ID | `user_id` parameter |
| actions | tools | e.g., `GITHUB_CREATE_ISSUE` is a *tool* |
| apps / appType | toolkits | e.g., `github` is a *toolkit* |
| integration / integration ID | auth config / auth config ID | `auth_config_id` parameter |
| connection | connected account | `connected_accounts` namespace |
| ComposioToolSet / OpenAIToolSet | `Composio` class with a provider | `Composio(provider=...)` |
| toolset | provider | e.g., `OpenAIProvider` |

If a user says "entity ID", they mean `user_id`. If they say "integration", they mean "auth config". Always respond using the current terminology.
