Authorization code flow with PKCE

[Bolero23]

Hi all/Johan Haleby

I have a question if anyone has any experience with the Authorization code with PKCE flow as I need help on how to do this via Rest Assured.

These are the parameters which I send and which works for me when I use via Postman but I don't know how to work through Rest Assured:

Grant Type: Authorization Code (With PKCE) 

Callback URL: https://example-app/swagger-ui/oauth2-redirect.html

Auth URL: https://auth-example.com/connect/authorize Access Token URL: https://auth-example.com/connect/token

Client ID: provided by development

Client Secret: provided by development

Scope: provided by development

Code Challenge Method: SHA-256

Client Authentication: Send as Basic Auth header

If you have a solution or experience feel free to suggest

Thanks,
Bosko
