After enabling it under **APIs & Services**, wait a few minutes and retry. **Choose managed or customer-owned OAuth.** Use Composio-managed OAuth for the standard connection flow. Use a custom Google OAuth app when you need control over scopes, consent-screen branding, or Google Cloud project policy. For custom OAuth, configure the app name and branding in that project and use the redirect URL shown by Composio's current auth-config flow. ## Troubleshoot Google Tasks OAuth and tool calls [#troubleshoot-google-tasks-oauth-and-tool-calls] **Remove unverified scopes when Google reports “App is blocked.”** This error usually means the OAuth client is requesting scopes that Google has not verified for that client. Remove additional scopes beyond the defaults, or use a custom OAuth app and submit the scopes for verification. **Validate scopes when OAuth returns `Error 400: invalid_scope`.** Verify the requested scopes and their formatting against the [Google OAuth scopes documentation](https://developers.google.com/identity/protocols/oauth2). **Reconnect when tool calls return 401.** A 401 usually means the access token is no longer valid. Re-authenticate the connected account and retry. --- 📚 **More documentation:** [View all docs](https://docs.composio.dev/llms.txt) | [Changelog](https://docs.composio.dev/docs/changelog.md) | [Glossary](https://docs.composio.dev/llms.mdx/reference/glossary) | [Examples](https://docs.composio.dev/llms.mdx/examples) | [API Reference](https://docs.composio.dev/llms.mdx/reference) --- # 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 Composio supports two integration modes: **Native Tools** (with a provider package) and **MCP** (no provider package needed). ### Native Tools ```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 // ✅ 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 ``` For other providers, pass the provider explicitly. Provider packages follow the naming convention: `composio_` for Python, `@composio/` 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.
