Unable to get Authentication code

Unable to get Authentication code

Hi Team,

We're currently sending a request to the endpoint (/oauth/v2/auth) via Postman, but we're encountering an issue: we're receiving an HTML response and struggling to extract the authorization code from it. Is there a method to retrieve the code in JSON format by incorporating additional header parameters, or perhaps another alternative approach we could explore?
​
Kindly help with the resolution of this query ASAP.
