Inquiry About API for Stock Closing Price Data

Generating an auth code and obtaining access tokens using that auth code is a three-step process. The first two steps must be done in a web browser:

  1. Perform Authentication: Follow the detailed instructions at Perform Authentication.
  2. Receive Auth Code: To complete this step, visit Receive Auth Code.
  3. Generate Access Token: Finally, refer to Generate Access Token to generate the access token.

You’ll receive the auth code on the Redirect URL during the second step, which you’ll need to use in the process of generating an access token in the third step.

I recommend reviewing the documentation to understand better the process: Authentication Documentation.
