About Connect API
Webull Connect API provides a standardized set of APIs that enables third-party platforms to connect with a growing base of Webull brokerage accounts.
The Connect API uses OAuth 2.0 for authentication. OAuth 2.0 is a standardized and widely adopted authorization framework that allows third-party platforms to securely and seamlessly integrate with Webull’s OAuth endpoints.
For detailed instructions on how to connect your application to Webull using OAuth 2.0, please refer to the OAuth Integration Guide.
The Main Function: Supported instruments include U.S. stocks, futures, and crypto.
- Authorization: Authentication and authorization using the OAuth 2.0 protocol.
- Account: Query account info.
- Assets: Query account balance, positions.
