Struct ComposioClient 

pub struct ComposioClient { /* private fields */ }

Main client for interacting with Composio API

The client manages HTTP connections and configuration for all API requests. It includes automatic retry logic for transient failures and proper error handling.

Example

use composio_sdk::client::ComposioClient;

let client = ComposioClient::builder()
    .api_key("your_api_key")
    .build()?;

Implementations

impl ComposioClient

pub fn builder() -> ComposioClientBuilder

Create a new client builder

Returns a ComposioClientBuilder that can be used to configure and build a ComposioClient instance.

Example

use composio_sdk::client::ComposioClient;

let client = ComposioClient::builder()
    .api_key("your_api_key")
    .build()?;

pub fn http_client(&self) -> &Client

Get a reference to the HTTP client

This is useful for advanced use cases where you need direct access to the underlying reqwest client.

pub fn config(&self) -> &ComposioConfig

Get a reference to the configuration

Returns the configuration used by this client.

pub fn create_session(&self, user_id: impl Into<String>) -> SessionBuilder<'_>

Create a new session for a user

Returns a SessionBuilder that can be used to configure and create a Tool Router session for the specified user.

Arguments

• user_id - User identifier for session isolation

Example

use composio_sdk::client::ComposioClient;

let client = ComposioClient::builder()
    .api_key("your_api_key")
    .build()?;

let session = client
    .create_session("user_123")
    .toolkits(vec!["github", "gmail"])
    .send()
    .await?;

pub async fn get_session( &self, session_id: impl Into<String>, ) -> Result<Session, ComposioError>

Get an existing session by ID

Retrieves session details for a previously created Tool Router session. This is useful for inspecting session configuration and available tools.

Arguments

• session_id - The session ID to retrieve

Errors

Returns an error if:

• Session not found (404)
• Network error occurs
• API returns an error response

Example

use composio_sdk::client::ComposioClient;

let client = ComposioClient::builder()
    .api_key("your_api_key")
    .build()?;

let session = client.get_session("sess_abc123").await?;
println!("Session ID: {}", session.session_id());
