OpenAI Providers

The OpenAI Provider is the default provider for the Composio SDK. It transforms Composio tools into a format compatible with OpenAI’s function calling capabilities through both the Responses and Chat Completion APIs.

Setup

By default, the OpenAI Provider is installed when you install the Composio SDK. You can also install it manually:

$
pip install composio_openai==0.8.0

The OpenAI Provider is used by default when you initialize the Composio SDK but you can explicitly specify it.

1
from openai import OpenAI
2
from composio import Composio
3
from composio_openai import OpenAIProvider
4
5
# Initialize Composio client with OpenAI Provider
6
composio = Composio(provider=OpenAIProvider())
7
openai = OpenAI()

Chat Completion API

Chat Completion API is the industry standard for building LLM-powered applications. Chat completions are also adopted and used by many other LLM providers apart from OpenAI.

1
user_id = "user@acme.org"
2
tools = composio.tools.get(user_id=user_id, toolkits=["HACKERNEWS"])
3
4
response = openai.chat.completions.create(
5
    model="gpt-4.1",
6
    tools=tools,
7
    messages=[
8
        {"role": "user", "content": "What's the latest Hackernews post about?"},
9
    ],
10
)
11
12
# Execute the function calls.
13
result = composio.provider.handle_tool_calls(response=response, user_id=user_id)
14
print(result)
15
# will return the raw response from the HACKERNEWS API.

Modifiers

Modifiers are functions that can be used to intercept and optionally modify the schema, the tool call request and the response from the tool call.

OpenAI provider modifiers are the standard framework modifiers. Read more here: Modifying tool schemas
