Create Client Token

POST 
/openapi/auth/client/token/create

Generates an access token and refresh token pair for end-user applications to directly access Webull services. This endpoint must be called from your institution's backend service with valid AK/SK credentials. The access token authorizes API calls, while the refresh token enables token renewal. Creating a new token pair for an existing customer immediately invalidates any previously issued tokens for that customer.
• Access token expires in approximately 2 hours (may vary slightly)
• Refresh token expires in 15 days
• Frequency limit: Rate limit 600 requests per minute
• Note: This access_token is used to access Market Data API
