# Toolkit Versioning (/docs/tools-direct/toolkit-versioning)

> If you're building an agent, we recommend using [sessions](/docs/configuring-sessions) instead. Sessions handle toolkit versions automatically so you don't have to manage them yourself.

Toolkit versioning ensures your tools behave consistently across deployments. You can pin specific versions in production, test new releases in development, and roll back when needed.

To view available versions, go to [Dashboard](https://platform.composio.dev) > **All Toolkits** > select a toolkit. The version dropdown shows the latest and all available versions:

<img alt="Toolkit version selector on the Composio dashboard" src={__img0} placeholder="blur" />

You can also find the latest version for each toolkit on the [Toolkits](/toolkits) page in the docs. Select a toolkit to see its current version and available tools.

> Starting from Python SDK v0.9.0 and TypeScript SDK v0.2.0, specifying versions is required for manual tool execution.

# Configuration methods

Configure toolkit versions using one of three methods:

## SDK initialization

**Python:**

```python
from composio import Composio

# Pin specific versions for each toolkit
composio = Composio(
    api_key="YOUR_API_KEY",
    toolkit_versions={
        "github": "20251027_00",
        "slack": "20251027_00",
        "gmail": "20251027_00"

)
```

**TypeScript:**

```typescript
import { Composio } from "@composio/core";

// Pin specific versions for each toolkit
const composio = new Composio({
    apiKey: "YOUR_API_KEY",
    toolkitVersions: {
        github: "20251027_00",
        slack: "20251027_00",
        gmail: "20251027_00"

});
```

## Environment variables

```bash
# Set versions for specific toolkits
export COMPOSIO_TOOLKIT_VERSION_GITHUB="20251027_00"
export COMPOSIO_TOOLKIT_VERSION_SLACK="20251027_00"
export COMPOSIO_TOOLKIT_VERSION_GMAIL="20251027_00"
```

## Per-execution override

**Python:**

```python
from composio import Composio

composio = Composio(api_key="YOUR_API_KEY")

# Specify version directly in execute call
result = composio.tools.execute(
    "GITHUB_LIST_STARGAZERS",
    arguments={
        "owner": "ComposioHQ",
        "repo": "composio"
    },
    user_id="user-k7334",
    version="20251027_00"  # Override version for this execution
)
print(result)
```

**TypeScript:**

```typescript
import { Composio } from "@composio/core";

const composio = new Composio({ apiKey: "YOUR_API_KEY" });

// Specify version directly in execute call
const result = await composio.tools.execute("GITHUB_LIST_STARGAZERS", {
    userId: "user-k7334",
    arguments: {
        owner: "ComposioHQ",
        repo: "composio"
    },
    version: "20251027_00"  // Override version for this execution
});
console.log(result);
```

# Version format

Versions follow the format `YYYYMMDD_NN`:

* `YYYYMMDD`: Release date
* `NN`: Sequential release number

```python
# Production
toolkit_versions = {"github": "20251027_00"}

# Development
toolkit_versions = {"github": "latest"}
```

> Never use `latest` in production. It can introduce breaking changes.

# Version resolution order

1. Per-execution version (highest priority)
2. SDK initialization version
3. Environment variable (toolkit-specific)

# Managing versions

Check available versions using:

**Python:**

```python
# Get toolkit information including available versions
toolkit = composio.toolkits.get(slug="github")

# Extract and print version information
print(f"Toolkit: {toolkit.name}")
print(f"Current Version: {toolkit.meta.version}")
print(f"Available Versions: {toolkit.meta.available_versions}")
```

**TypeScript:**

```typescript
import { Composio } from '@composio/core';
const composio = new Composio({ apiKey: 'your_api_key' });
// Get toolkit information including available versions
const toolkit = await composio.toolkits.get("github");

// Extract and print version information
console.log("Toolkit:", toolkit.name);
console.log("Available Versions:", toolkit.meta.availableVersions);
console.log("Latest Version:", toolkit.meta.availableVersions?.[0]);
```

# Composio SDK — Instructions for AI Code Generators

**Context:** This page documents the **direct tool execution API**. For most applications, the session-based pattern (`composio.create(user_id)` + `session.tools()`) is simpler — but if the user is here, they likely want direct execution.

---

## Key Patterns

### Authenticating Users

Create an **Auth Config** on [platform.composio.dev](https://platform.composio.dev), then use the auth config ID to generate a hosted auth URL:

```python
from composio import Composio

composio = Composio()
connection = composio.connected_accounts.link(
    user_id="user_123",
    auth_config_id="ac_...",  # from platform dashboard
)
print(connection.redirect_url)  # send user here to authenticate
```

```typescript
import { Composio } from "@composio/core";

const composio = new Composio();
const connection = await composio.connectedAccounts.link("user_123", "ac_...", {
    callbackUrl: "https://your-app.com/callback",
});
console.log(connection.redirectUrl); // send user here to authenticate
```

### Executing Tools

```python
tools = composio.tools.get("user_123", tools=["GITHUB_CREATE_ISSUE"])

result = composio.tools.execute(
    "GITHUB_CREATE_ISSUE",
    {"owner": "org", "repo": "repo", "title": "Bug report"},
    user_id="user_123",
)
```

```typescript
const tools = await composio.tools.get("user_123", { tools: ["GITHUB_CREATE_ISSUE"] });

const result = await composio.tools.execute("GITHUB_CREATE_ISSUE", {
    userId: "user_123",
    arguments: { owner: "org", repo: "repo", title: "Bug report" },
});
```

## Rules

1. **`user_id` is required** — pass it to `tools.get()`, `tools.execute()`, and `provider.handle_tool_calls()`.
2. **`tools.execute()` signature** — Python: `execute(slug, arguments_dict, *, user_id=...)` (arguments is the second positional param). TypeScript: `execute(slug, { userId, arguments })`.
3. **Provider at init** — `Composio(provider=OpenAIProvider())` in Python, `new Composio({ provider: new OpenAIProvider() })` in TypeScript. Defaults to OpenAI if omitted.
4. **Correct provider imports** — `composio_<provider>` for Python, `@composio/<provider>` for TypeScript. For OpenAI Agents SDK use `composio_openai_agents` / `@composio/openai-agents`.
